CVE-2023-2195: 
Java vulnerability analysis and mitigation

CVE-2023-2195 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Code Dx Plugin for Jenkins. The vulnerability was discovered in versions 3.1.0 and earlier of the plugin, and was publicly disclosed on May 16, 2023. This security issue affects the Jenkins continuous integration and deployment platform, specifically the Code Dx Plugin component (Jenkins Advisory).

The vulnerability stems from the plugin's failure to perform proper permission checks in several HTTP endpoints and not requiring POST requests for these endpoints. The issue has been assigned a Medium severity rating. The vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified URL through the plugin's HTTP endpoints (Jenkins Advisory, GitHub Lab).

The vulnerability enables attackers to perform Server-Side Request Forgery (SSRF) attacks, allowing them to send requests to arbitrary hosts. While the attacker cannot read the response, they can potentially use this vulnerability to scan internal networks and potentially access sensitive internal services (GitHub Lab).

The vulnerability has been fixed in Code Dx Plugin version 4.0.0. The updated version requires POST requests and implements appropriate permission checks for the affected HTTP endpoints. Users are advised to upgrade to this version to mitigate the vulnerability (Jenkins Advisory).
