Versions before undertow 2.0.25.SP1 and jboss-remoting 5.0.14.SP1 are believed to be vulnerable.

CVE-2022-1319 [HIGH] CWE-252 CVE-2022-1319: A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response pack 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-2022-4492 [HIGH] CWE-918 CVE-2022-4492: The undertow client is not checking the server identity presented by the server certificate in https The undertow client is not checking the server identity presented by the server certificate in https connections.

CVE-2021-3690 [HIGH] CWE-400 CVE-2021-3690: A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memor 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-2022-1259 [HIGH] CVE-2022-1259: A flaw was found in Undertow. A potential security issue in flow control handling by the browser ove 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-2017-12196 [MEDIUM] CWE-287 CVE-2017-12196: undertow before versions 1.4.18.SP1, 2.0.2.Final, 1.4.24.Final was found vulnerable when using Diges undertow before versions 1.4.18.SP1, 2.0.2.Final, 1.4.24.Final was found vulnerable when using Digest authentication, the server does not ensure that the value of URI in the Authorization header matches the URI in HTTP request line. This allows the attacker to cause a MITM attack and access the desired content on the server.

CVE-2020-10719 [MEDIUM] CWE-444 CVE-2020-10719: A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTT A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTTP requests with large chunk sizes. This flaw allows an attacker to take advantage of HTTP request smuggling.

CVE-2020-10705 [HIGH] CWE-770 CVE-2020-10705: A flaw was discovered in Undertow in versions before Undertow 2.1.1.Final where certain requests to A flaw was discovered in Undertow in versions before Undertow 2.1.1.Final where certain requests to the "Expect: 100-continue" header may cause an out of memory error. This flaw may potentially lead to a denial of service.

CVE-2017-2666 [MEDIUM] CVE-2017-2666: It was discovered in Undertow that the code that parsed the HTTP request line permitted invalid characters It was discovered in Undertow that the code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, pe

CVE-2018-1114 [MEDIUM] CVE-2018-1114: It was found that URLResource It was found that URLResource.getLastModified() in Undertow closes the file descriptors only when they are finalized which can cause file descriptors to exhaust. This leads to a file handler leak.

CVE-2024-1459 [MEDIUM] CVE-2024-1459: A path traversal vulnerability was found in Undertow 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-2018-1067 [MEDIUM] CVE-2018-1067: In Undertow before versions 7.1.2.CR1, 7.1.2.GA it was found that the fix for CVE-2016-4993 was inco In Undertow before versions 7.1.2.CR1, 7.1.2.GA it was found that the fix for CVE-2016-4993 was incomplete and Undertow web server is vulnerable to the injection of arbitrary HTTP headers, and also response splitting, due to insufficient sanitization and validation of user input before the input is used as part of an HTTP header value.

CVE-2024-3653 [MEDIUM] CVE-2024-3653: A vulnerability was found in Undertow A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request.
