CVE-2022-1319 2 Netapp, Redhat 7 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 4 more 2022-11-07 N/A 7.5 HIGH
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.
CVE-2022-1259 2 Netapp, Redhat 10 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 7 more 2022-11-07 N/A 7.5 HIGH
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.
CVE-2021-3690 1 Redhat 8 Enterprise Linux, Fuse, Integration Camel K and 5 more 2022-08-26 N/A 7.5 HIGH
A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability.
CVE-2022-2053 1 Redhat 3 Integration Camel K, Jboss Fuse, Undertow 2022-08-11 N/A 7.5 HIGH
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.
CVE-2019-19343 2 Netapp, Redhat 4 Active Iq Unified Manager, Jboss-remoting, Jboss Enterprise Application Platform and 1 more 2022-05-03 5.0 MEDIUM 7.5 HIGH
A flaw was found in Undertow when using Remoting as shipped in Red Hat Jboss EAP before version 7.2.4. A memory leak in HttpOpenListener due to holding remote connections indefinitely may lead to denial of service. Versions before undertow 2.0.25.SP1 and jboss-remoting 5.0.14.SP1 are believed to be vulnerable.
CVE-2019-14888 2 Netapp, Redhat 6 Active Iq Unified Manager, Jboss Data Grid, Jboss Enterprise Application Platform and 3 more 2022-04-01 5.0 MEDIUM 7.5 HIGH
A vulnerability was found in the Undertow HTTP server in versions before 2.0.28.SP1 when listening on HTTPS. An attacker can target the HTTPS port to carry out a Denial Of Service (DOS) to make the service unavailable on SSL.
