What is CVE-2024-6162?
CVE-2024-6162 is a high-severity vulnerability in Red Hat EAP 8.0.1, published on 20 Jun 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A vulnerability was found in Undertow, where URL-encoded request paths can be mishandled during concurrent requests on the AJP listener. This issue arises because the same buffer is used to decode the paths for multiple requests simultaneously, leading to incorrect path information being processed. As a result, the server may attempt to access the wrong path, causing errors such as "404 Not Found" or other application failures. This flaw can potentially lead to a denial of service, as legitimate resources become inaccessible due to the path mix-up.
