tomcat: Apache Tomcat: Access control bypass due to off-by-one error in RewriteValve [N] flag processing

A flaw was found in Apache Tomcat. An off-by-one error in the RewriteValve's N flag processing causes rewrite rules to restart at the second rule instead of the first. This vulnerability may allow an attacker to bypass intended access controls...

tomcat: Apache Tomcat: Security constraint bypass due to improper access control

A flaw was found in Apache Tomcat. This improper access control and incorrect authorization vulnerability allows an attacker to bypass security constraints. This occurs when a security constraint for a longer path is specified before a more restrictive constraint for a shorter sub-path, potential...

tomcat: Apache Tomcat: Denial of Service via WebSocket chat example

A flaw was found in Apache Tomcat. This uncontrolled resource consumption vulnerability, located in the WebSocket chat example, allows a remote attacker to cause a Denial of Service DoS by exhausting system resources. This can lead to the affected system becoming unresponsive or crashing...

tomcat: Apache Tomcat: Local information disclosure via Unix domain socket TOCTOU race condition

A flaw was found in Apache Tomcat. A Time-of-check Time-of-use TOCTOU race condition exists when creating Unix domain sockets. This vulnerability allows an unauthorized local user to exploit the timing window to gain access to the Unix domain socket. This could lead to information disclosure or...

tomcat: Apache Tomcat: Authentication bypass via limited replay attack in DIGEST authenticator

A flaw was found in Apache Tomcat. This vulnerability, an authentication bypass by capture-replay, affects the DIGEST authenticator. A remote attacker can exploit this by making a specially crafted DIGEST authenticated request with a nonceCount at the upper boundary of the replay window. This...
