A vulnerability in the web framework of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system.
The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary commands and execute the affected function. An exploit could allow the attacker to run arbitrary commands on the affected system with the privilege of the root user.
Cisco confirmed the vulnerability in a security advisory and released software updates.
Indicators of Compromise
Cisco ISE versions prior to 18.104.22.1685-5, 22.214.171.1248-7, 126.96.36.199-10, 1.1.3, 1.1.4, or 188.8.131.529-2 are vulnerable.
The vulnerability is due to improper input validation on input to functions used by the Cisco ISE web framework.
An authenticated, remote attacker could exploit the vulnerability by sending malicious input to a vulnerable function. The processing of the malicious input could trigger the execution of arbitrary commands on the system with the privileges of the root user.
Users must authenticate to the affected system to exploit the vulnerability, greatly reducing the source of exploitation.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to access local systems.
Administrators are advised to monitor affected systems.
