Jenkins Remote Code Execution Vulnerability

Jenkins contains a remote code execution vulnerability. This vulnerability that could allowed attackers to transfer a serialized Java SignedObject object to the remoting-based Jenkins CLI, that would be deserialized using a new ObjectInputStream, bypassing the existing blocklist-based protection mechanism.

Added to KEV: 2025-10-02Federal patch deadline: 2025-10-23
Required Action (CISA)

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Risk Analysis

This Jenkins vulnerability allows remote code execution by bypassing existing security mechanisms through deserialization of a Java SignedObject. With an EPSS score of 0.94508, there is a very high likelihood of this vulnerability being exploited, demanding immediate action.

This vulnerability is actively exploited in the wild and is part of CISA's KEV catalog, confirming its use by attackers.

Recommended Action

To mitigate this remote code execution flaw, ensure Jenkins is updated to a patched version, and review configurations related to the Jenkins CLI and remoting.

Technical Analysis

CVE-2017-1000353 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2017-1000353 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
