-
Anonymous users can access some administration pages
Several administrative web pages of the Cisco Show and Share can be accessed without prior user authentication. These include pages for accessing Encoders and Pull Configurations, Push Configurations, Video Encoding Formats, and Transcoding. Note: The web server runs as a non-root user. Details regarding the impact of accessing each one of these administrative pages are included in the Impact section of this Cisco Security Advisory.
Vulnerability Scoring Details
Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss
- CSCto73758 - Anonymous users can access some administration pages
CVSS Base Score - 7.5 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - Partial
CVSS Temporal Score - 6.2 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed
- CSCto69857 - Cisco Show and Share arbitrary code execution

CVSS Temporal Score - 5.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed
Impact
These vulnerabilities have the following impact on Cisco Show and Share:
-
CSCto73758: Anonymous users can access some administration pages Several administrative web pages of the Cisco Show and Share can be accessed without prior user authentication. The impact of the different administrative web pages include:
Encoders Configurations +---------------------- The Encoders Configuration pages have a direct impact on live events. If all of the encoders from the encoders' configurations are removed, then a live event cannot be created. An encoder or a push configuration is required in order for a live event to be created. This page also reveals information about the encoders, such as Encoder IP Address and associated username.
Push Configurations +------------------ The Push Configurations and Encoders Configuration pages have a direct impact on live events. If all of the encoders of push configurations are removed, then a live event cannot be created. An encoder or a push configuration is required in order for a live event to be created.
Video Encoding Formats +--------------------- Video encoding formats have a direct impact on the encoders. Even with an encoder or a push configuration configured, if no video format is specified then the encoder cannot encode the video stream for the live event.
Transcoding +---------- This page does not have a direct impact on live events or the encoders. This page will only set a task to be executed for transcoding. Transcoding is a process of deriving digital media files that use one codec from digital media files that use a different codec; the source file is not changed or destroyed. If all tasks are removed the set task for transcoding will not be executed.
Software Versions and Fixes
When considering software upgrades, also consult: http://www.cisco.com/go/psirt And any subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.
Each row of the software table (below) names a Cisco SnS release train. If a given release train is vulnerable, then the earliest possible releases that contains the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table.

Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at:\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\nhttp://intellishield.cisco.com/security/alertmanager/cvss \n\n\n\n* CSCto73758 - Anonymous users can access some administration pages \n\nCVSS Base Score - 7.5\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - Partial\n Integrity Impact - Partial\n Availability Impact - Partial\n\nCVSS Temporal Score - 6.2\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\n\n* CSCto69857 - Cisco Show and Share arbitrary code execution \n\nCVSS Base Score - 6.5\n Access Vector - Network\n Access Complexity - Low\n Authentication - Single\n Confidentiality Impact - Partial\n Integrity Impact - Partial\n Availability Impact - Partial\n\nCVSS Temporal Score - 5.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\nImpact\n======\n\nThese vulnerabilities have the following impact on Cisco Show and\nShare:\n\n * CSCto73758: Anonymous users can access some administration pages\n Several administrative web pages of the Cisco Show and Share can\n be accessed without prior user authentication. The impact of the\n different administrative web pages include:\n\n Encoders Configurations\n +----------------------\n The Encoders Configuration pages have a direct impact on live\n events. If all of the encoders from the encoders\u0027 configurations\n are removed, then a live event cannot be created. An encoder or a\n push configuration is required in order for a live event to be\n created. This page also reveals information about the encoders,\n such as Encoder IP Address and associated username. \n\n Push Configurations\n +------------------\n The Push Configurations and Encoders Configuration pages have a\n direct impact on live events. If all of the encoders of push\n configurations are removed, then a live event cannot be created. \n An encoder or a push configuration is required in order for a\n live event to be created. \n\n Video Encoding Formats\n +---------------------\n Video encoding formats have a direct impact on the encoders. Even\n with an encoder or a push configuration configured, if no video\n format is specified then the encoder cannot encode the video\n stream for the live event. \n\n\n Transcoding\n +----------\n This page does not have a direct impact on live events or the\n encoders. This page will only set a task to be executed for\n transcoding. Transcoding is a process of deriving digital media\n files that use one codec from digital media files that use a\n different codec; the source file is not changed or destroyed. If\n all tasks are removed the set task for transcoding will not be\n executed. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult:\nhttp://www.cisco.com/go/psirt \nAnd any subsequent advisories to determine exposure and a complete\nupgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nEach row of the software table (below) names a Cisco SnS release\ntrain. If a given release train is vulnerable, then the earliest\npossible releases that contains the fix (along with the anticipated\ndate of availability for each, if applicable) are listed in the\n\"First Fixed Release\" column of the table. The \"Recommended Release\"\ncolumn indicates the releases which have fixes for all the published\nvulnerabilities at the time of this Advisory. A device running a\nrelease in the given train that is earlier than the release in a\nspecific column (less than the First Fixed Release) is known to be\nvulnerable. Cisco recommends upgrading to a release equal to or later\nthan the release in the \"Recommended Releases\" column of the table. \n\nEach row of the software table (below) names a Cisco Show and Share\nrelease train. If a given release train is vulnerable, then the\nearliest possible releases that contains the fix are listed in the\n\"First Fixed Release\" column of the table. A device running a release\nin the given train that is earlier than the \"First Fixed Release\" is\nknown to be vulnerable. Cisco recommends upgrading to a release equal\nto or later than the release in the \"First Fixed Release\" column of\nthe table. \n\nWARNING: Please read the release notes on Cisco Show and Share\nversion 5.2(3) regarding MCS Server Appliance support. \n\nThe following MCS Server Appliances are not supported in Cisco Show\nand Share version 5.2(3), and administrators should use a recommended\nrelease of 5.2(2.1) or later:\n\n * MCS 7825-H2\n * MCS 7825-H3\n * MCS 7835-H1\n * MCS 7835-H2\n\nFor further information for support MCS Server Appliances consult the\nrelease notes for Cisco Digital Media Suite 5.2.x at the following\nlink: \nhttp://www.cisco.com/en/US/docs/video/digital_media_systems/5_x/5_2/dms/release/notes/dms52rn.html#wp232018\n\n+-------------------------------------------------------------------+\n| Cisco Show and Share Release | First Fixed Release |\n|-------------------------------+-----------------------------------|\n| 5(2) | Vulnerable; migrate to 5.2(2.1) |\n|-------------------------------+-----------------------------------|\n| 5.2(1) | Vulnerable; migrate to 5.2(2.1) |\n|-------------------------------+-----------------------------------|\n| 5.2(2) | 5.2(2.1) |\n|-------------------------------+-----------------------------------|\n| 5.2(3) | Not Vulnerable |\n+-------------------------------------------------------------------+\n\nNote: Read the WARNING provided above regarding Cisco Show and Share\nversion 5.2(3). \n\nCisco Show and Share software upgrades, can be download from: \nhttp://www.cisco.com/cisco/software/type.html?mdfid=280171242\u0026catid=268438145\n\nWorkarounds\n===========\n\nThere are no workarounds for these vulnerabilities. \n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
