The XML parser used in ConeXware PowerArchiver before 20.10.02 allows processing of external entities, which might lead to exfiltration of local files over the network (via an XXE attack).

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.
