Undertow Ajp-Listener Vulnerability: URL-Encoded Request Path Information Can Be Broken

CVE-2024-6162

What is CVE-2024-6162?

A vulnerability in Undertow affects the processing of URL-encoded request paths on the AJP listener when handling concurrent requests. The issue stems from the sharing of a buffer used for decoding paths across multiple requests, which may result in the server misinterpreting the path, leading to errors like '404 Not Found' or other application failures. This flaw can hinder access to legitimate resources, potentially resulting in a denial of service. Organizations relying on Undertow for handling AJP traffic should assess their systems for exposure to this vulnerability.
