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 · unedited
Heap-based buffer overflow in Cisco TelePresence TC Software 4.x through 6.x before 6.0.1 and TE Software 4.x and 6.0.x before 6.0.2 allows remote attackers to execute arbitrary code via crafted SIP packets, aka Bug ID CSCud81796.

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 confidence

Heap-based buffer overflow vulnerability in Cisco TelePresence TC and TE software allows remote attackers to execute arbitrary code via crafted SIP packets. The overflow occurs in heap memory, enabling attackers to overwrite adjacent memory structures and achieve code execution.

MitigationUpgrade Cisco TelePresence TC Software to version 6.0.1 or later, and TE Software to version 6.0.2 or later. If immediate patching is not possible, consider restricting SIP traffic at network boundaries or disabling SIP processing if not required.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the TelePresence product
    Determine whether the system is running Cisco TelePresence TC Software or TE Software. This is typically visible in the system administration interface, firmware filename, or product documentation.
    Affected if The product is Cisco TelePresence TC or TE software.
  2. Check the installed software version
    Access the TelePresence admin interface or use the system status command (such as 'show system' or 'xstatus') to retrieve the exact firmware version number.
    Affected if The version matches one of the affected versions: TE = 4.1.0, 4.1.1, 4.1.2, 4.1.3, 6.0, 6.0.1; TC = 4.0.0, 4.0.1, 4.0.4, 4.1.1, 4.1.2, 4.2.0, 4.2.1, 4.2.2, 4.2.3, 4.2.4, 5.0.0, 5.0.1.
  3. Verify SIP is enabled
    Check the SIP configuration in the TelePresence admin interface under Network or SIP settings, or use the command line to display SIP status (such as 'show sip' or 'configuration sip').
    Affected if SIP processing is enabled and the device is reachable via SIP traffic.
  4. Review network exposure to SIP
    Inspect firewall rules or access control lists to determine if the TelePresence device is exposed to untrusted SIP traffic from external networks.
    Affected if The SIP port (typically 5060) is open to untrusted or external networks.

You are affected if the device runs Cisco TelePresence TC or TE software version 4.0.0 through 6.0.1 (specific to the listed versions) and has SIP enabled and exposed to network traffic.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Cisco TelePresence TC Software to version 6.0.1 or later, and TE Software to version 6.0.2 or later. If immediate patching is not possible, consider restricting SIP traffic at network boundaries or disabling SIP processing if not required.

Recommended fix High confidence

TelePresence TC Software: upgrade to 6.0.1 or later; TelePresence TE Software: upgrade to 6.0.2 or later

  1. 1. Identify the current TelePresence software version by accessing the admin interface or running 'show version' command
  2. 2. Determine if the system is running TC Software or TE Software from the version number
  3. 3. For TelePresence TC Software: Upgrade to version 6.0.1 or later (or latest stable 6.x release)
  4. 4. For TelePresence TE Software: Upgrade to version 6.0.2 or later (or latest stable 6.0.x release)
  5. 5. Download the appropriate firmware from Cisco's software download center (tools.cisco.com) using valid Cisco service contract credentials
  6. 6. Upload the new software image to the TelePresence device via the admin web interface or SCP
  7. 7. Initiate the software upgrade via the web interface or CLI command 'software upgrade'
  8. 8. After upgrade completes, verify the new version is running with 'show version' command
Caveat Review Cisco release notes for migration path if upgrading across major version jumps; ensure compatibility with any integrated systems before upgrading in production
