CVE-2026-76449: Cisco Identity Services Engine SQL Injection Vulnerability
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.

Frequently Asked Questions
Who can exploit this issue?
An attacker must be able to reach the affected APIs remotely and possess valid administrative credentials. Unauthenticated users cannot exploit it based on the available information.
What could a successful attacker do?
A successful exploit allows arbitrary SQL or HQL queries against the underlying database. This could let the attacker view or modify data they are not authorized to access.
What is the immediate mitigation if patching cannot be performed?
The available information identifies valid administrative credentials as a prerequisite. Restricting administrative access and protecting or revoking potentially exposed administrative credentials can reduce exposure, though no vendor-specific workaround is provided.
