Name of the Vulnerable Software and Affected Versions Jenkins Buckminster Plugin versions 1.1.1 and earlier

Description The issue is related to insufficient authorization procedures in the Jenkins Buckminster Plugin, allowing remote attackers with Overall/Read permission to gain unauthorized access to protected information. This can be exploited to check for the existence of an attacker-specified file path on the Jenkins controller file system. A sequence of requests can be used to effectively list the Jenkins controller file system.

Recommendations For Jenkins Buckminster Plugin versions 1.1.1 and earlier, as a temporary workaround, consider disabling the form validation method until a patch is available. Restrict access to the plugin to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
