An issue was discovered in the 3CX Phone system (web) management console 12.5.44178.1002 through 12.5 SP2. The Content.MainForm.wgx component is affected by XXE via a crafted XML document in POST data. There is potential to use this for SSRF (reading local files, outbound HTTP, and outbound DNS).
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.
