CVE-2021-25122 - Information Exposure vulnerability

Severity: Medium2021-04-13

Security Advisories

Abstract

When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request.

The tomcat-coyote package is vulnerable to Information Exposure. The process method in AbstractProtocol.class does not properly handle HTTP/2 Cleartext (h2c) connections between multiple clients, responding with the request headers and partial body of one connection to another. An attacker can exploit this to gain access to sensitive information meant for a different client.

The Oxygen Feedback product incorporates the Apache Tomcat as a third-party library. This advisory was opened to address the potential impact of this third-party library vulnerability.
