Synopsis

The remote Apache Tomcat server is affected by multiple vulnerabilities

Description

The version of Tomcat installed on the remote host is prior to 9.0.43. It is, therefore, affected by multiple vulnerabilities as referenced in the vendor advisory.

- An information disclosure vulnerability exists when responding to new h2c connection requests, Apache Tomcat versions 9.0.0.M1 to 9.0.41 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. (CVE-2021-25122)

- when using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. (CVE-2021-25329)

- A remote code execution vulnerability via deserialization exists when using Apache Tomcat 9.0.0.M1 to 9.0.41 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. (CVE-2021-25329)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Tomcat version 9.0.43 or later.
