CVE-2024-6235Public exploit

Unauthenticated session-secret disclosure via trusted internal headers

Published Jul 10, 2024 · Updated Apr 23, 2025

Improper authentication in NetScaler Console 14.1 before 14.1-25.53 allows remote attackers to read session secrets over the management network. The internal mps_secret endpoint trusts caller-supplied internal-request, tenant, and user headers and returns the ADM_SESSIONID secret. Access to the Console IP is the only reported gate; exposed session and administrative credentials permit unauthorized console access.
