CVE-2020-2184: 
Java vulnerability analysis and mitigation

A cross-site request forgery (CSRF) vulnerability was discovered in Jenkins CVS Plugin versions 2.15 and earlier. The vulnerability was identified as CVE-2020-2184 and was disclosed on May 6, 2020. The affected component is the Jenkins CVS Plugin, which is used for CVS source code management integration in Jenkins (Jenkins Advisory, NVD).

The vulnerability stems from the plugin's failure to require POST requests in several HTTP endpoints. This security flaw is classified as a CSRF vulnerability with a CVSS v3.1 base score of 4.3 (Medium), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N. The vulnerability is tracked as CWE-352 (Cross-Site Request Forgery) (NVD).

The vulnerability allows attackers to create and manipulate tags in the CVS repository and connect to attacker-specified URLs through cross-site request forgery attacks. This could potentially lead to unauthorized repository modifications and malicious connections (Jenkins Advisory).

The vulnerability requires user interaction to be exploited, as indicated by the CVSS metrics. An attacker would need to trick an authenticated user into performing specific actions through CSRF attacks (NVD).

The vulnerability has been fixed in Jenkins CVS Plugin version 2.16, which now requires POST requests for the affected HTTP endpoints. Users are advised to upgrade to this version or later to address the security issue (Jenkins Advisory).

The vulnerability was reported by Oleg Nenashev from CloudBees, Inc., who discovered and reported the issue along with other Jenkins plugin vulnerabilities. The Jenkins project acknowledged the contribution in their security advisory (Jenkins Advisory).
