Summary

CVE-2023-35143 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Maven Repository Server. Its CVSS base score is 5.4 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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 Maven Repository Server Plugin 1.10 and earlier contains a stored cross-site scripting vulnerability because it fails to escape build artifact versions displayed on the Build Artifacts As Maven Repository page. The affected component is the Jenkins plugin that renders Maven repository views from project build data.

Attackers who can control Maven project versions inside a pom.xml file can inject arbitrary script content that executes in the browsers of other users who view the affected page. Successful exploitation allows the attacker to perform actions as the victim user within the Jenkins instance, with impact limited to confidentiality and integrity exposure under the reported CVSS vector.

The Jenkins security advisory SECURITY-3156 and the associated OpenWall disclosure provide the official details and recommended actions for this issue. The EPSS score has remained flat at 0.0756 with no material increase after disclosure.

Adversaries may try to gather information about registered local system services.
T1011 Exfiltration Over Other Network Medium Exfiltration
Adversaries may attempt to exfiltrate data over a different network medium than the command and control channel.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).

PR.PS-02 partial match
blocks

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
