Deserialization Sap

Description

SAP NetWeaver Enterprise Portal Federated Portal Network is vulnerable when a privileged user can upload untrusted or malicious content which, when deserialized, could potentially lead to a compromise of confidentiality, integrity, and availability of the host system.

Analysis

SAP NetWeaver Enterprise Portal Federated Portal Network is vulnerable when a privileged user can upload untrusted or malicious content which, when deserialized, could potentially lead to a compromise of confidentiality, integrity, and availability of the host system.

Technical Context

Insecure deserialization occurs when untrusted data is used to reconstruct objects, allowing attackers to manipulate serialized data to execute arbitrary code. This vulnerability is classified as Deserialization of Untrusted Data (CWE-502).

Remediation

Avoid deserializing untrusted data. Use safe serialization formats (JSON instead of native serialization). Implement integrity checks on serialized data.
