Synopsis

Apache Tomcat 9.0.0.M1 < 9.0.38 Information Disclosure

Description

The version of Apache Tomcat installed on the remote host is 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57. It is, therefore, affected by a vulnerability. If an HTTP/2 client exceeds the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it is possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This can lead to users seeing responses for unexpected resources.

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.38 or later.
