CVE-2023-3223: Red Hat JBoss Enterprise Application Platform

High severity, CVSS 7.5. EPSS: 2.7% chance of exploitation in the next 30 days.

A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null.
