Invensys » Wonderware Intouch : Security Vulnerabilities, CVEs,

Invensys Wonderware InTouch HMI 2012 R2 and earlier allows remote attackers to read arbitrary files, send HTTP requests to intranet servers, or cause a denial of service (CPU and memory consumption) via an XML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

Invensys Wonderware InTouch 2012 R2 and earlier and Siemens ProcessSuite use a weak encryption algorithm for data in Ps_security.ini, which makes it easier for local users to discover passwords by reading this file.
