CVE-2026-76448
Cisco Identity Services Engine SQL Injection Vulnerability
Description
A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct an SQL or HQL injection attack on an affected device. This vulnerability is due to insufficient validation of user-supplied input to the affected APIs before it is used to build database queries. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to execute arbitrary SQL or HQL queries against the underlying database, which could allow the attacker to view or modify data that they are not authorized to access. To exploit this vulnerability, the attacker must have valid administrative credentials.
