Multiple vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow a remote attacker to access or manipulate data, obtain sensitive information, or cause a reload of certificate and key material on an affected device. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. 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 ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-notice-jfxK98ZP"]. In addition, for further documentation of improvements and fixes in Cisco Identity Services Engine, see Cisco Identity Services Engine Security Hardening Release: September 2026 ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-hardening-ise-XU5EwX5T"].

A vulnerability in an internal service of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to retrieve sensitive configuration information from an affected device. This vulnerability is due to missing authentication on the Policy Runtime Repository Table (PRRT) service. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to obtain sensitive configuration information from the affected device.

Ein Angreifer kann mehrere Schwachstellen in Cisco Identity Services Engine (ISE) und ISE-PIC ausnutzen, um beliebigen Code auszuführen – sogar mit Root-Rechten –, Sicherheitsmaßnahmen zu umgehen, Berechtigungen zu erweitern, SQL-Injection-Angriffe durchzuführen, Sitzungen zu übernehmen, sensible Informationen oder Anmeldedaten offenzulegen, Daten zu manipulieren, einen Denial-of-Service-Zustand auszulösen und Cross-Site-Scripting-Angriffe durchzuführen.
