high Tenable Cloud Security Plugin ID 435881

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without
 triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients
 to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol
 bug, this highlights a common implementation weakness that can be exploited to cause a denial of service
 (DoS). (CVE-2025-9784)

Solution

Update the io.undertow:undertow-core library and its related packages to version 2.2.38.Final or later.
