CVE-2023-5379 – Undertow: ajp request closes connection exceeding maxrequestsize
https://notcve.org/view.php?id=CVE-2023-5379
12 Dec 2023 — 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 ... • https://access.redhat.com/errata/RHSA-2023:4509 • CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2022-2053 – undertow: Large AJP request may cause DoS
https://notcve.org/view.php?id=CVE-2022-2053
05 Aug 2022 — When a POST request comes through AJP and the request exceeds the max-post-size limit (maxEntitySize), Undertow's AjpServerRequestConduit implementation closes a connection without sending any response to the client/proxy. This behavior results in that a front-end proxy marking the backend worker (application server) as an error state and not forward requests to the worker for a while. In mod_cluster, this continues until the next STATUS request (10 seconds intervals) from the application server updates the... • https://bugzilla.redhat.com/show_bug.cgi?id=2095862&comment#0 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-1319
07 Jun 2022 — A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet instead of a CPONG. Se ha encontrado un fallo en Undertow.
