CVE-2025-24503

Session hijacking via crafted session-fixation link

Published Jan 30, 2025 · Updated Feb 5, 2025

Session fixation in Symantec Privileged Access Management 3.4.6, 4.1.0 through 4.1.8, and 4.2.0 allows attackers to hijack a user's session. A specially crafted link causes the PAM server to fix the targeted user's session, but Broadcom has not disclosed the affected request handler or session-token operation. Exploitation requires an unauthenticated attacker in an adjacent network position to induce an active PAM user to open the link, exposing that user's privileged session.
