CVE-2016-8672
The integrated web server on Siemens SIMATIC CP 343-1 Advanced before 3.0.53, SIMATIC CP 443-1 Advanced, SIMATIC S7-300 CPU, and SIMATIC S7-400 CPU devices does not set the secure flag for unspecified cookies in an https session, which makes it easier for remote attackers to capture these cookies by intercepting their transmission within an http session.
