CVE-2024-36456

Unauthenticated command execution via crafted upgrade upload

Published Jul 15, 2024 · Updated Aug 2, 2024

Code injection in Symantec Privileged Access Management 4.1.0 through 4.1.7 and 3.4.6 allows remote attackers to execute commands through an upgrade upload. The PAM upgrade endpoint accepts a specially crafted upgrade file for command execution; Broadcom has not published the underlying parsing or validation defect. No authentication or user interaction is required, but the attacker must reach the appliance from an adjacent network; exploitation grants command execution on the PAM system.
