Name of the Vulnerable Software and Affected Versions Jenkins AbsInt a³ Plugin versions 1.1.0 and earlier

Description The issue arises from the plugin not configuring its XML parser to prevent XML external entity (XXE) attacks. This allows attackers who can control the Project File (APX) contents to have Jenkins parse a crafted XML document, potentially leading to the extraction of secrets from the Jenkins controller or server-side request forgery.

Recommendations For Jenkins AbsInt a³ Plugin versions 1.1.0 and earlier, consider disabling the XML parser functionality until a patch is available to prevent XXE attacks. Restrict access to the Project File (APX) to minimize the risk of exploitation. Avoid using external entities in XML documents until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
