Apache Tomcat 7.0.x < 7.0.88 Denial of Service

high Nessus Plugin ID 121121

Synopsis

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

Description

According to its self-reported version number, the Apache Tomcat instance listening on the remote host is 7.0.x prior to 7.0.88.
It is, therefore, affected by the following vulnerability:

- A denial of service (DoS) vulnerability exists in Tomcat due to improper overflow handling in the UTF-8 decoder. An unauthenticated, remote attacker can exploit this issue to cause an infinite loop in the decoder, leading to a denial of service condition.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 7.0.88 or later.
