Insecure Deserialization in SAP NetWeaver Enterprise Portal Federated Portal Network
CVE-2025-42980 is a critical insecure deserialization vulnerability in SAP NetWeaver Enterprise Portal, specifically in the Federated Portal Network (FPN) functionality. According to the provided content, the issue arises when a privileged user can upload untrusted or malicious content that is later deserialized without sufficient validation. The supporting material indicates that malicious serialized objects may be embedded in portal metadata, including XML-based configuration or role data, and processed through FPN-related features such as Remote Role Assignment (RRA) and Web Services for Remote Portlets (WSRP). When the malicious content is deserialized, it can lead to arbitrary code execution and full compromise of confidentiality, integrity, and availability of the underlying host system.
