An Improper XML Parser Configuration issue was discovered in Schneider Electric Wonderware Historian Client 2014 R2 SP1 and prior. An improperly restricted XML parser (with improper restriction of XML external entity reference, or XXE) may allow an attacker to enter malicious input through the application which could cause a denial of service or disclose file contents from a server or connected network.
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.
