A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.
This vulnerability is potentially used
```
org.owasp.webgoat.lessons.csrf.CSRFGetFlag (Application)
-> io.undertow.servlet.spec.HttpServletRequestImpl (Extension)
-> io.undertow.servlet.core.ServletUpgradeListener (Extension)
-> ❌ org.xnio.StreamConnection (Vulnerable Component)
```
### Vulnerability Details
A flaw was found in XNIO, specifically in the notifyReadClosed method. The issue revealed this method was logging a message to another expected end. This flaw allows an attacker to send flawed requests to a server, possibly causing log contention-related performance concerns or an unwanted disk fill-up.
This vulnerability is potentially used
```

-> org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration$1 (Extension)

-> io.undertow.server.protocol.ajp.AjpReadListener (Extension)
-> ❌ io.undertow.server.protocol.ajp.AjpServerRequestConduit (Vulnerable Component)
```
### Vulnerability Details
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. However, luckily, mod_proxy_balancer has "forcerecovery" setting (On by default; this parameter can force the immediate recovery of all workers without considering the retry parameter of the workers if all workers of a balancer are in error state.). So, unlike mod_cluster, mod_proxy_balancer does not result in responding "503 Service Unavailable". An attacker could use this behavior to send a malicious request and trigger server errors, resulting in DoS (denial of service). This flaw was fixed in Undertow 2.2.19.Final, Undertow 2.3.0.Alpha2.
This vulnerability is potentially used
```
org.owasp.webgoat.lessons.csrf.CSRFGetFlag (Application)

...
-> io.undertow.servlet.core.ServletContainerImpl (Extension)
-> io.undertow.servlet.core.DeploymentManagerImpl (Extension)
-> ❌ io.undertow.security.impl.ClientCertAuthenticationMechanism (Vulnerable Component)
```
### Vulnerability Details
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
This vulnerability is potentially used
```
org.owasp.webgoat.lessons.hijacksession.HijackSessionAssignment (Application)
-> io.undertow.servlet.spec.HttpServletResponseImpl (Extension)
-> ❌ io.undertow.servlet.spec.ServletPrintWriter (Vulnerable Component)
```
### Vulnerability Details
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.
This vulnerability is potentially used
```
org.owasp.webgoat.container.WebSecurityConfig (Application)
-> org.springframework.security.config.annotation.web.configuration.EnableWebSecurity (Extension)

```
### Vulnerability Details
A flaw was found in Undertow. A potential security issue in flow control handling by the browser over HTTP/2 may cause overhead or a denial of service in the server. This flaw exists because of an incomplete fix for CVE-2021-3629.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
