Cisco Identity Search Engine SXP REST API SQL Injection Vulnerability

CVSS 3.1 9.1 CRITICALCheck source for fixed versionsKEV status unknown

cve-program · CVE-2026-20284

Published

A vulnerability in the SXP REST API of Cisco ISE could allow an authenticated, remote attacker to conduct SQL injection attacks. This vulnerability is due to insufficient validation of user-supplied input in REST API calls. An attacker could exploit this vulnerability by sending crafted input to an affected device. A successful exploit could allow the attacker to view or modify data on the underlying database for the affected device. In single-node deployments, successful exploitation of this vulnerability could cause the affected ISE node to become unavailable, resulting in a DoS condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored. To exploit this vulnerability, the attacker must have valid administrative credentials, have the SXP service enabled, and have at least one SXP connection configured.
