Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability targets the web-based management interface of Cisco IP Phone 6800, 7800, and 8800 Series; monitor for unauthenticated remote requests to the web UI of these devices that may indicate command injection or stack overflow exploitation attempts.
  • Track Cisco bug IDs CSCwc78400, CSCwd39132, and CSCwd40494 for patch status and associated indicators on affected Cisco IP Phone firmware versions.
  • CWE-78 (OS Command Injection) and CWE-121 (Stack-based Buffer Overflow) are the vulnerability classes; detection rules should look for anomalous input patterns in HTTP requests to the phone web management interface consistent with command injection payloads.
  • ·No workarounds are available for these vulnerabilities; only vendor-supplied software updates remediate the issue.
