A vulnerability in the web-based management interface of Cisco Identity Services Engine could allow an authenticated, remote attacker to inject arbitrary commands on the underlying operating system. This vulnerability is due to improper validation of user input within requests as part of the web-based management interface. An attacker could exploit this vulnerability by manipulating requests to the web-based management interface to contain operating system commands. A successful exploit could allow the attacker to execute arbitrary operating system commands on the underlying operating system with the privileges of the web services user. Cisco has not yet released software updates that address this vulnerability.

Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability exists in the web-based management interface of Cisco ISE; monitor for anomalous or crafted HTTP requests to the management interface that contain OS command injection payloads (CWE-78).
  • Successful exploitation results in OS command execution under the privileges of the web services user; monitor for unexpected process spawning from web service processes on Cisco ISE nodes.
  • Track Cisco Bug IDs CSCwc98823, CSCwc98828, and CSCwc98831 for patch availability and additional technical details related to this command injection vulnerability.
  • ·Exploitation requires the attacker to be authenticated; ensure monitoring covers authenticated sessions to the Cisco ISE web-based management interface, not just unauthenticated access attempts.
  • ·The vulnerability is due to improper validation of user input within requests; WAF or input-validation rules targeting the ISE management interface should focus on OS command metacharacters in request parameters.
