Apache Tomcat 7.0.x < 7.0.75 NIO HTTP Connector Information Disclosure

medium Nessus Network Monitor Plugin ID 700671

Synopsis

The remote Apache Tomcat server is affected by an information disclosure vulnerability.

Description

According to its self-reported version number, the Apache Tomcat service running on the remote host is 7.0.x prior to 7.0.75. It is therefore, affected by an information disclosure vulnerability in error handling during send file processing by the NIO HTTP connector, in which an error can cause the current Processor object to be added to the Processor cache multiple times. This allows the same Processor to be used for concurrent requests. An unauthenticated, remote attacker can exploit this issue, via a shared Processor, to disclose sensitive information, such as session IDs, response bodies related to another request, etc.

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

Solution

Upgrade to Apache Tomcat version 7.0.75 or later.
