Summary

Multiple vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct SQL or HQL injection attacks on an affected device.

These vulnerabilities are due to insufficient validation of user-supplied input to the affected APIs before it is used to build database queries. An attacker could exploit these vulnerabilities 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 these vulnerabilities, the attacker must have valid administrative credentials.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

This advisory is part of a group of advisories. For a complete list of the advisories and links to them, see Cisco Advance Notification for Publication of September 16, 2026, Security Advisories.
