QID 730662: Apache Tomcat Request mix-up with h2c Vulnerability (CVE-2021-25122)

Apache Tomcat is an open source web server and servlet container developed by the Apache Software Foundation.

The fix for CVE-2020-9484 was incomplete. When using a highly unlikely configuration edge case, the Tomcat instance was still vulnerable to CVE-2020-9484. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published non-upgrade mitigations for CVE-2020-9484 also apply to this issue.

Affected versions:
Apache Tomcat 8.5.0 to 8.5.61

QID Detection Logic (Unauthenticated):
This QID sends a HTTP GET request to an invalid URL and based on the response confirms the vulnerable instance of Apache Tomcat running on the host.

Successful exploitation of this vulnerability could reveal sensitive information to an unauthorized attacker.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
