CVE-2024-1459 1 Redhat 1 Undertow 2024-02-27 N/A 5.3 MEDIUM
A path traversal vulnerability was found in Undertow. This issue may allow a remote attacker to append a specially-crafted sequence to an HTTP request for an application deployed to JBoss EAP, which may permit access to privileged or restricted files and directories.
CVE-2020-1745 1 Redhat 1 Undertow 2024-02-16 7.5 HIGH 9.8 CRITICAL
A file inclusion vulnerability was found in the AJP connector enabled with a default AJP configuration port of 8009 in Undertow version 2.0.29.Final and before and was fixed in 2.0.30.Final. A remote, unauthenticated attacker could exploit this vulnerability to read web application files from a vulnerable server. In instances where the vulnerable server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types and trigger this vulnerability to gain remote code execution.
CVE-2023-5379 1 Redhat 3 Jboss Enterprise Application Platform, Single Sign-on, Undertow 2023-12-20 N/A 7.5 HIGH
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 malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS).
CVE-2023-1108 2 Netapp, Redhat 17 Oncommand Workflow Automation, Build Of Quarkus, Decision Manager and 14 more 2023-12-10 N/A 7.5 HIGH
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.
CVE-2023-3223 1 Redhat 8 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Text-only Advisories and 5 more 2023-12-10 N/A 7.5 HIGH
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.
CVE-2022-4492 1 Redhat 10 Build Of Quarkus, Integration Camel For Spring Boot, Integration Camel K and 7 more 2023-12-10 N/A 7.5 HIGH
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.
CVE-2022-2053 1 Redhat 3 Integration Camel K, Jboss Fuse, Undertow 2023-12-10 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-2022-1259 2 Netapp, Redhat 10 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 7 more 2023-12-10 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-2022-2764 2 Netapp, Redhat 9 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 6 more 2023-12-10 N/A 4.9 MEDIUM
A flaw was found in Undertow. Denial of service can be achieved as Undertow server waits for the LAST_CHUNK forever for EJB invocations.
CVE-2021-3690 1 Redhat 8 Enterprise Linux, Fuse, Integration Camel K and 5 more 2023-12-10 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-2022-1319 2 Netapp, Redhat 7 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 4 more 2023-12-10 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-2021-3859 2 Netapp, Redhat 6 Cloud Secure Agent, Oncommand Insight, Oncommand Workflow Automation and 3 more 2023-12-10 N/A 7.5 HIGH
