Apache Tomcat 7.0.x < 7.0.8 NIO Connector DoS

medium Nessus Network Monitor Plugin ID 5795


The remote web server is affected by a denial of service vulnerability.


According to its self-reported version number, the instance of Apache Tomcat listening on the remote host is prior to 7.0.8. It is, therefore, affected by a denial of service vulnerability. An error, involving the NIO HTTP connector, exists such that the limit 'maxHttpHeaderSize' is not enforced thereby allowing a denial of service condition when memory is exhausted.

Note that Nessus Network Monitor has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to Apache Tomcat 7.0.8 or later.
