Detailsinfo

A vulnerability classified as problematic has been found in Schweizerische Steuerkonferenz Library taxstatement.jar 2.2.2/2.2.4 on Windows. Affected is the function DocumentBuilder of the component PDF Handler. The manipulation with an unknown input leads to a xml external entity reference vulnerability. CWE is classifying the issue as CWE-611. The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

When the XML is read from the codes in the PDF and parsed using a DocumentBuilder, the default settings of the DocumentBuilder allow for an XXE (XML External Entity) attack.
