CVE-2025-42980 is a critical insecure deserialization vulnerability in SAP NetWeaver Enterprise Portal Federated Portal Network. The vulnerable condition arises when a privileged user is able to upload untrusted or malicious serialized content that is later deserialized without sufficient validation. Available reporting indicates the issue affects Federated Portal Network functionality in SAP NetWeaver Enterprise Portal, including scenarios involving remote portal content exchange and metadata synchronization. Deserialization of attacker-controlled objects can result in execution of unintended logic and potentially arbitrary code execution on the underlying host, leading to compromise of confidentiality, integrity, and availability.
