A vulnerability in the Cisco IOx application hosting environment could allow an authenticated, remote attacker to execute arbitrary commands as root on the underlying host operating system. This vulnerability is due to incomplete sanitization of parameters that are passed in for activation of an application. An attacker could exploit this vulnerability by deploying and activating an application in the Cisco IOx application hosting environment with a crafted activation payload file. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying host operating system.

Detection & IOCsextracted from sources · hover to see the quote

  • Exploit requires deploying and activating an application in the Cisco IOx application hosting environment with a crafted activation payload file containing unsanitized parameters
  • Monitor Cisco IOx application activation events for anomalous or malformed parameters in activation payload files, particularly those that may contain command injection sequences
  • Successful exploitation results in arbitrary command execution as root on the underlying host OS — monitor for unexpected root-level process spawning from IOx hosting processes
  • ·Attacker must be authenticated to exploit this vulnerability; prioritize monitoring for authenticated IOx users deploying or activating applications
  • ·Cisco Bug IDs CSCwc66882 and CSCwc67015 are associated with this vulnerability and can be used to track affected software versions in Cisco's bug search tool
  • ·No workarounds are available; detection must rely on behavioral monitoring and patching
