Newell Brands DYMO ID 1.5.1.71 parses job files using XmlDocument.Load() without disabling DTD processing. The PC Job Files view automatically parses every recognized job file extension on folder browse. A crafted file on any browsed network share can perform SSRF, capture NTLMv2 credentials, read local files, or crash the process. Fixed in 1.6.0.
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.
