Remote code execution and privilege escalation in Cisco Identity Services Engine allows authenticated attackers with Read Only Admin privileges to execute arbitrary operating system commands via crafted HTTP requests, resulting in full root access. The vulnerability, rated 9.9 (Critical), impacts multiple ISE versions; in single-node deployments, the affected device may become unavailable, causing denial of service. No active exploitation (KEV) or public exploit code has been identified, and the EPSS score of 0.21% indicates low likelihood of widespread attacks.

DescriptionCVE.org
A vulnerability in Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have at least Read Only Admin credentials.
This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain user-level access to the underlying operating system and then elevate privileges to root. In single-node ISE deployments, successful exploitation of these vulnerabilities could cause the affected ISE node to become unavailable, resulting in a denial of service (DoS) condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored.

Attack Technique
Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
