漏洞描述
Alt-n/MDaemon Security Gateway through 8.5.0 is susceptible to XML injection via SecurityGateway.dll?view=login. An attacker can inject an arbitrary XML argument by adding a new parameter in the HTTP request URL. As a result, the XML parser fails the validation process and discloses information such as protection used (2FA), admin email, and product registration keys.
