Lifecycle Timeline
2DescriptionCVE.org
A vulnerability in Cisco ISE and ISE-PIC 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 valid administrative 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 deployments, successful exploitation of this vulnerability 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.
AnalysisAI
Authenticated remote command execution in Cisco Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC) allows administrators to run arbitrary OS commands and escalate to root via a crafted HTTP request. The flaw, tracked as CVE-2026-20181 and reported by Cisco with a CVSS 3.1 score of 9.1 (scope-changed), can also crash single-node deployments and deny network access to unauthenticated endpoints. There is no public exploit identified at time of analysis.
