How to fix?

Upgrade Debian:unstable trafficserver to version 9.2.5+ds-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream trafficserver package and not the trafficserver package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Apache Traffic Server forwards malformed HTTP chunked trailer section to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable.

This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4.

Users can set a new setting (proxy.config.http.drop_chunked_trailers) not to forward chunked trailer section. Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
