How to fix?

Upgrade RHEL:7 jws5-tomcat-servlet-4.0-api to version 0:9.0.43-11.redhat_00011.1.el7jws or higher.
This issue was patched in RHSA-2021:2561.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jws5-tomcat-servlet-4.0-api package and not the jws5-tomcat-servlet-4.0-api package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The fix for CVE-2020-9484 was incomplete. 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.
