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.

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 •

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 •
