SRS Policy Manager 6.X is affected by an XML External Entity Injection (XXE) vulnerability due to a misconfigured XML parser that processes user-supplied DTD input without sufficient validation. A remote unauthenticated attacker can potentially exploit this vulnerability to read system files as a non-root user and may be able to temporarily disrupt the ESRS service.

Weakness

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.
