DescriptionNVD

AnalysisAI

Pippo through 1.11.0 allows remote code execution via a command to java.lang.ProcessBuilder because the XstreamEngine component does not use XStream's available protection mechanisms to restrict. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch 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. Pippo through 1.11.0 allows remote code execution via a command to java.lang.ProcessBuilder because the XstreamEngine component does not use XStream's available protection mechanisms to restrict unmarshalling. Affected products include: Pippo. Version information: through 1.11.0.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid deserializing untrusted data. Use safe serialization formats (JSON). Implement integrity checks and type allowlists.
