CVE-2021-27492: (0Day) Siemens Solid Edge Viewer 3DXML File Parsing XML External Entity Processing Information Disclosure Vulnerability
First published: Thu May 27 2021(Updated: )
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Siemens Solid Edge Viewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of 3DXML files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process.
