Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. To exploit these vulnerabilities, the attacker must have valid device credentials, but does not need Administrator privileges. These vulnerabilities are due to insufficient validation of user-supplied input for certain configuration options. An attacker could exploit these vulnerabilities by using crafted input within the device configuration GUI. A successful exploit could allow the attacker to execute arbitrary commands on the device, including on the underlying operating system, which could also affect the availability of the device.

Detection & IOCsextracted from sources · hover to see the quote

  • Exploit requires authenticated access to the web-based management interface GUI; monitor for crafted/anomalous input submitted to device configuration pages by non-Administrator authenticated users
  • Attacker does not need Administrator privileges — alert on OS-level command execution originating from the FMC web management process, especially from lower-privileged authenticated sessions
  • Successful exploitation may impact device availability; monitor for unexpected process spawning or system instability on FMC hosts as a post-exploitation indicator
  • Track Cisco Bug IDs CSCwf63210 and CSCwf63215 for patch status and vendor-released indicators associated with this vulnerability
  • ·Vulnerability class includes both path traversal (CWE-22) and OS command injection (CWE-78); insufficient validation of user-supplied input in configuration options is the root cause
  • ·No workarounds are available; the only remediation is applying Cisco-released software updates
