Apache Tomcat 9.0.0.M11 < 9.0.0.M17 nextRequest Information Disclosure

high Nessus Plugin ID 99362

Synopsis

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

Description

The version of Apache Tomcat installed on the remote host is 9.0.0.M11 or later but prior to 9.0.0.M17. It is, therefore, affected by an information disclosure vulnerability in the nextRequest() function in Http11InputBuffer.java due to improper limits of a ByteBuffer being set. An unauthenticated, remote attacker can exploit this to disclose ByteBuffer data associated with a different request.

Note that Nessus 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 9.0.0.M17 or later.

Note that the vulnerability was also fixed in version 9.0.0.M16;
however, this version was never publicly released.
