CVE-2015-5537: Siemens ruggedcom rox ii firmware cleartext storage of sensitive data vulnerability

Siemens · Ruggedcom Rox Ii Firmware

The SSL layer of the HTTPS service in Siemens RuggedCom ROS before 4.2.0 and ROX II does not properly implement CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a different vulnerability than CVE-2014-3566.
