Description
A critical vulnerability in SAP NetWeaver Application server for Java Log Viewer enables authenticated administrator users to exploit unsafe Java object deserialization. Successful exploitation can lead to full operating system compromise, granting attackers complete control over the affected system. This results in a severe impact on the confidentiality, integrity, and availability of the application and host environment.
Analysis
A critical vulnerability in SAP NetWeaver Application server for Java Log Viewer enables authenticated administrator users to exploit unsafe Java object deserialization. Successful exploitation can lead to full operating system compromise, granting attackers complete control over the affected system. This results in a severe impact on the confidentiality, integrity, and availability of the application and host environment.
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).
Affected Products
Affected: SAP NetWeaver Application server for Java Log Viewer enables authenticated administrator users to exploit unsafe Java object deserialization
Remediation
Avoid deserializing untrusted data. Use safe serialization formats (JSON instead of native serialization). Implement integrity checks on serialized data.
