AnalysisAI

The REST Plugin in Apache Struts 2.1.1 through 2.3.x before 2.3.34 and 2.5.x before 2.5.13 uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Actively exploited in the wild (cisa kev) and public exploit code available.

Technical ContextAI

This vulnerability is classified as Deserialization of Untrusted Data (CWE-502), which allows attackers to execute arbitrary code through malicious serialized objects. The REST Plugin in Apache Struts 2.1.1 through 2.3.x before 2.3.34 and 2.5.x before 2.5.13 uses an XStreamHandler with an instance of XStream for deserialization without any type filtering, which can lead to Remote Code Execution when deserializing XML payloads. Affected products include: Apache Struts, Cisco Digital Media Manager, Cisco Hosted Collaboration Solution, Cisco Media Experience Engine, Cisco Network Performance Analysis. Version information: through 2.3..

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Avoid deserializing untrusted data. Use safe serialization formats (JSON). Implement integrity checks and type allowlists.
