CVE-2022-45395: 
Java vulnerability analysis and mitigation

CCCC Plugin 0.6 and earlier contains a vulnerability identified as CVE-2022-45395, discovered and disclosed on November 15, 2022. The vulnerability affects the Jenkins CCCC Plugin, which is used for generating code metrics reports. This security issue was reported by CC Bomber from Kitri BoB (Jenkins Advisory, OSS Security).

The vulnerability is an XML External Entity (XXE) attack vulnerability that occurs because the plugin does not properly configure its XML parser to prevent XXE attacks. The severity is rated as Medium according to the CVSS scoring system. The vulnerability specifically affects the 'Publish CCCC Report' post-build step functionality (Jenkins Advisory).

This vulnerability allows attackers who can control the contents of the report file for the 'Publish CCCC Report' post-build step to have agent processes parse a crafted file that uses external entities. This can lead to extraction of secrets from the Jenkins agent or enable server-side request forgery attacks. However, the real impact is limited to narrow circumstances where attackers can control XML files but cannot modify build steps, Jenkinsfiles, or test code executed on the agents (Jenkins Advisory).

As of the advisory's publication date, there is no official fix available for this vulnerability in the CCCC Plugin. The latest affected version is 0.6, and users should monitor for updates (Jenkins Advisory).
