A flaw was found in Undertow. Denial of service can be achieved as Undertow server waits for the LAST_CHUNK forever for EJB invocations. Se ha encontrado un fallo en Undertow. Puede producirse una denegación de servicio ya que el servidor de Undertow espera eternamente el LAST_CHUNK para las invocaciones EJB A flaw was found in Undertow with EJB invocations. This flaw allows an attacker to generate a valid HTTP request and send it to the server on an established connection after removing the LAST_CHUNK from the bytes, causing a denial of service. • https://bugzilla.redhat.com/show_bug.cgi?id=2117506 https://security.netapp.com/advisory/ntap-20221014-0006 https://access.redhat.com/security/cve/CVE-2022-2764 • CWE-400: Uncontrolled Resource Consumption •

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-2053 – undertow: Large AJP request may cause DoS
https://notcve.org/view.php?id=CVE-2022-2053
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 server state. So, in the worst case, it can result in "All workers are in error state" and mod_cluster responds "503 Service Unavailable" for a while (up to 10 seconds). In mod_proxy_balancer, it does not forward requests to the worker until the "retry" timeout passes. • https://bugzilla.redhat.com/show_bug.cgi?id=2095862&comment#0 https://issues.redhat.com/browse/UNDERTOW-2133 https://access.redhat.com/security/cve/CVE-2022-2053 https://bugzilla.redhat.com/show_bug.cgi?id=2095862 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-1319
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. Para una respuesta AJP 400, EAP 7 envía inapropiadamente el flag de reúso habilitado aunque JBoss EAP cierra la conexión. es producido un fallo cuando la conexión es reusada después de un 400 por CPING ya que lee en el segundo paquete de respuesta SEND_HEADERS en lugar de un CPONG • https://access.redhat.com/security/cve/CVE-2022-1319 https://bugzilla.redhat.com/show_bug.cgi?id=2073890 https://github.com/undertow-io/undertow/commit/1443a1a2bbb8e32e56788109d8285db250d55c8b https://github.com/undertow-io/undertow/commit/7c5b3ab885b5638fd3f1e8a935d5063d68aa2df3 https://issues.redhat.com/browse/UNDERTOW-2060 https://security.netapp.com/advisory/ntap-20221014-0006 • CWE-252: Unchecked Return Value •
