CVE-2016-2201
The CVE concerns the Siemens SIMATIC S7-1500 CPU family (before firmware version 1.8.3) where specially crafted packets on TCP port 102 can bypass the device’s replay protection. The issue stems from insufficient replay protection/control flow management, enabling remote attackers to bypass prote...

tomcat: three DIGEST authentication implementation issues
The replay-countermeasure functionality in the HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 tracks cnonce aka client nonce values instead of nonce aka server nonce and nc aka nonce-count values, which makes it easi...

tomcat: Multiple weaknesses in HTTP DIGEST authentication
The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the...
