CVE-2023-5309Network attack vector

Authenticated identity takeover via fixed SAML sessions

Published Nov 7, 2023 · Updated Sep 4, 2024

Session fixation in Puppet Enterprise before 2021.7.6 or 2023.5 allows remote authenticated users to assume another SAML identity. Perforce has not disclosed the affected SAML session-handling locus or the exact operation that preserves an attacker-controlled session identifier. Exploitation requires an existing low-privilege account and a SAML-enabled deployment; success exposes and permits modification of data available to the impersonated user.
