CVE-2015-4329
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe administrator web interface in Cisco TelePresence Video Communication Server (VCS) X8.5.2 allows remote authenticated users to execute arbitrary OS commands via crafted HTTP requests, aka Bug ID CSCuv11796.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Cisco TelePresence Video Communication Server (VCS) X8.5.2 contains a command injection vulnerability in its administrator web interface. Authenticated remote attackers can execute arbitrary operating system commands by sending specially crafted HTTP requests to the web interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed VCS software versionAccess the administrator web interface and navigate to the version information page, or use the CLI command 'xCommand SystemUnitSoftwareVersion' to retrieve the exact software version running on the deviceAffected if The installed version is exactly X8.5.2 (no other versions are listed as affected)
-
Confirm the administrator web interface is enabledCheck the VCS configuration via CLI using 'xConfiguration HTTP Proxy' or through the web interface under Administration > System settings to verify if the admin web service is activeAffected if The web interface is accessible on the default ports (HTTP port 80 or HTTPS port 443) and responds to authentication requests
-
Verify administrative user accountsReview the list of administrative users configured on the VCS through the web interface under Users > Administrator users, or use the CLI command 'xCommand UserList' to enumerate accountsAffected if Unexpected or unauthorized administrator accounts exist that were not created by your organization
-
Examine web server access logs for injection attemptsRetrieve and review web interface access logs from the VCS. Look for HTTP requests containing suspicious patterns such as shell metacharacters (e.g., |, ;, &, $ , `) in parameters, especially to endpoints that accept user inputAffected if Logs contain requests with command injection patterns or unexpected system commands in HTTP parameters
-
Check for signs of remote code executionReview system logs and examine the VCS filesystem for unexpected files, scripts, or processes. Look for new cron jobs or startup scripts that were not authored by your administratorsAffected if Unexpected files, processes, or scheduled tasks are present on the system that correspond to attacker-executed commands
A user is affected only if the installed Cisco TelePresence VCS software is exactly version X8.5.2 AND the administrator web interface is enabled and accessible, regardless of whether authentication has been compromised.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Cisco patch for bug ID CSCuv11796 to upgrade beyond X8.5.2, or upgrade to a patched version of the VCS software. Restrict administrative interface access to trusted networks and users.
