CVE-2024-46983Network attack vector

Remote code execution via denylist bypass

Published Sep 19, 2024 · Updated Sep 20, 2024

Deserialization in SOFA-Hessian before 3.5.5 allows remote attackers to execute arbitrary code through a crafted Hessian stream. During Hessian deserialization, the class filter consults an incomplete bundled security/serialize.blacklist and permits gadget classes needed by the chain. A reachable application must pass attacker-controlled Hessian data to the library; successful exploitation runs code in that application's process.
