Hi,
The following vulnerability was published for undertow.
CVE-2023-5379[0]:
| A flaw was found in Undertow. When an AJP request is sent that
| exceeds the max-header-size attribute in ajp-listener, JBoss EAP is
| marked in an error state by mod_cluster in httpd, causing JBoss EAP
| to close the TCP connection without returning an AJP response. This
| happens because mod_proxy_cluster marks the JBoss EAP instance as an
| error worker when the TCP connection is closed from the backend
| after sending the AJP request without receiving an AJP response, and
| stops forwarding. This issue could allow a malicious user could to
| repeatedly send requests that exceed the max-header-size, causing a
| Denial of Service (DoS).
