CVE-2026-20309

A vulnerability in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) allows an authenticated remote attacker to conduct an SQL or HQL injection attack. It is caused by insufficient validation of user-supplied input to the affected APIs before it is used to build database queries. An attacker with valid administrative credentials could execute arbitrary SQL or HQL queries and access data they are not authorized to view or modify.

A vulnerability in the Online Certificate Status Protocol (OCSP) responder of Cisco ISE and Cisco ISE-PIC allows an unauthenticated remote attacker to cause an administrative reload of the OCSP responder certificate and key material. It is caused by missing authentication on a function of the OCSP responder. An attacker could send a crafted request to trigger the reload of certificate and key material on demand.

A vulnerability in an API of Cisco ISE and Cisco ISE-PIC allows an authenticated remote attacker to read specific files on the underlying operating system of an affected device. It is caused by improper restriction of XML external entity references (XXE). An attacker could send a crafted request to read files that the underlying process has permission to access.

An internal security review by Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) engineering teams revealed multiple vulnerabilities related to improper privilege management (CWE-269). A software hardening release addressing these internally discovered issues has been made available.

Lack of server-side validation of Administrator permissions in the web-based management interface of Cisco Identity Services Engine (ISE) allows an authenticated remote attacker to modify parts of the configuration. The attacker submits a crafted HTTP request to modify descriptions of files on a specific page.

Insufficient validation of user-supplied input in IPsec Open API calls in Cisco ISE allows an authenticated remote attacker to inject arbitrary commands on the underlying operating system. Exploitation requires valid administrative credentials and a node with more than one network interface, one of which is an active IPsec tunnel.
