QID 730830: Apache Tomcat Information disclosure Vulnerability (CVE-2023-34981)

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

The fix for bug 66512 introduced a regression that was fixed as bug 66591. The regression meant that, if a response did not have any HTTP headers set, no AJP SEND_HEADERS message would be sent which in turn meant that at least one AJP based proxy (mod_proxy_ajp) would use the response headers from the previous request for the current request leading to an information leak.

Affected versions:
Apache Tomcat 10.1.8

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 - 5.4 severity.

Solution

Customers are advised to upgrade Apache Tomcat to the new version to remediate this vulnerability. For more information please refer to Apache Tomcat Security Advisory.
