Detailsinfo

A vulnerability classified as critical was found in Apache Batik up to 1.8. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a xml external entity reference vulnerability. The CWE definition for the vulnerability is 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.

In Apache Batik before 1.9, files lying on the filesystem of the server which uses batik can be revealed to arbitrary users who send maliciously formed SVG files. The file types that can be shown depend on the user context in which the exploitable application is running. If the user is root a full compromise of the server - including confidential or sensitive files - would be possible. XXE can also be used to attack the availability of the server via denial of service as the references within a xml document can trivially trigger an amplification attack.
