Synopsis

The remote Apache Tomcat server is affected by a vulnerability

Description

The version of Apache Tomcat installed on the remote host is 9.x prior to 9.0.62.

 - The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug in Apache Tomcat 10.1.0 to 10.1.0-M12, 10.0.0-M1 to 10.0.18, 9.0.0-M1 to 9.0.60 and 8.5.0 to 8.5.77 that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client. (CVE-2021-43980)

Solution

Upgrade to Apache Tomcat version 9.0.62 or later.
