NVD Description

Note: Versions mentioned in the description apply only to the upstream eap8-activemq-artemis-dto package and not the eap8-activemq-artemis-dto package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending \r\r\r as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests.
