CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-43044 is a high-severity Improper Check for Unusual or Exceptional Conditions (CWE-754) vulnerability in Jenkins Jenkins. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Service Stop (T1489); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Jenkins 2.470 and earlier, along with LTS 2.452.3 and earlier, contain a vulnerability in the Remoting library that permits agent processes to invoke the ClassLoaderProxy#fetchJar method and thereby read arbitrary files from the Jenkins controller file system. The flaw is tracked as CVE-2024-43044 and carries a CVSS 3.1 base score of 8.8.
An attacker who can run or control a Jenkins agent process can exploit the issue over the network with low attack complexity and without user interaction. Successful exploitation grants the agent read access to any file on the controller, resulting in high impact to confidentiality, integrity, and availability.
The Jenkins security advisory published on 7 August 2024 at https://www.jenkins.io/security/advisory/2024-08-07/#SECURITY-3430 addresses the issue. The associated EPSS score has remained at 0.6590 from disclosure through the present measurement, indicating steady but not sharply increasing exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation explicitly exercises unusual conditions to find missing or incorrect checks.
Input validation directly requires checking for unexpected or malformed conditions before they propagate.
Security engineering principles include structured handling of edge cases and exceptions during design.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure development practices directly require proper checks and handling for exceptional conditions throughout the SDLC.
Runtime monitoring of software and environments can detect adverse events triggered by unhandled exceptional conditions.
Generating logs of exceptions and errors enables detection of improper handling of unusual conditions.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development and acceptance verifies handling of error and exceptional conditions.
Logging can record unhandled exceptions but does not prevent the weakness itself.
Monitoring may detect symptoms of unhandled conditions but does not eliminate the root weakness.
Secure development life cycle mandates exception handling and input validation that directly prevent missing checks for unusual conditions.
Application security requirements explicitly call for handling of exceptional conditions and error paths.
Secure system architecture and engineering principles require robust error and exception handling mechanisms.
