Cisco ISE und ISE-PIC: Mehrere Schwachstellen
WID-SEC-2026-3425 · first 17.09.2026 · updated 17.09.2026 · CVSS 10,0
What it is about
Die Cisco Identity Services Engine (ISE) bietet eine attributbasierte Zugangs-Kontroll-Lösung. 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.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Code auszuführen – sogar mit Root-Rechten –
