A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with read-only privileges to perform command injection attacks on an affected system and execute arbitrary commands as the root user. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted commands to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.

Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability exists in the web-based management interface of Cisco IMC; monitor for crafted/anomalous commands sent to the IMC web management interface by authenticated users, especially those with read-only privileges attempting privileged operations.
  • Successful exploitation results in command execution as root on the underlying OS; monitor for unexpected root-level process spawning originating from the Cisco IMC web management process.
  • Track Cisco bug IDs CSCwr60021, CSCwr60889, CSCwr60894 for patch and indicator updates from Cisco PSIRT.
  • CWE-77 (Command Injection) and CWE-787 (Out-of-bounds Write) are the weakness types; inspect HTTP requests to the IMC management interface for shell metacharacters or oversized input payloads indicative of injection or buffer manipulation attempts.
  • ·Exploitation requires authentication; attacker must hold at least read-only privileges on the Cisco IMC web interface. Unauthenticated access alone is insufficient to trigger this vulnerability.
