Code execution via intercepted serialized objects
Published Jun 10, 2026 · Updated Jun 10, 2026
Insecure deserialization in Broadcom Layer7 API Gateway Policy Manager 11.2.1 allows man-in-the-middle attackers to execute code. Policy Manager deserializes arbitrary objects from attacker-modified client-to-gateway traffic; the published record does not identify the exact routine or serialization format. Exploitation requires low-privileged Policy Manager access and a traffic-interception position, and successful exploitation breaks security expectations or executes code.
