Executive Summary

The vulnerability exists in the Jenkins Script Security Plugin version 1402.v94c9ce464861 and earlier. It occurs because the plugin does not properly intercept implicit type casts applied to elements in typed for-each loops within sandboxed Groovy scripts. This flaw allows attackers who can provide such scripts to invoke arbitrary constructors, effectively bypassing the sandbox protection.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code by bypassing the sandbox restrictions in Jenkins. As a result, an attacker could potentially run unauthorized operations, compromise the Jenkins environment, access sensitive data, or disrupt automated build and deployment processes.
