|---|---|---|---|---|---|---|---|
| CVE-2020-27782 | — | >= 2.1.0, < 2.1.5 | 2.1.5 | Feb 23, 2021 | A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availa | ||
| CVE-2021-20220 | — | >= 2.1.0, < 2.1.6 | 2.1.6 | Feb 23, 2021 | A flaw was found in Undertow. A regression in the fix for CVE-2020-10687 was found. HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, | ||
| CVE-2020-10687 | — | < 2.2.0.Final | 2.2.0.Final | Sep 23, 2020 | A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache | ||

| CVE-2017-2666 | — | < 1.3.31 | 1.3.31 | Jul 27, 2018 | 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. | ||
| CVE-2017-12196 | — | >= 2.0.0.Alpha1, < 2.0.2.FInal | 2.0.2.FInal | Apr 18, 2018 | 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 | ||
| CVE-2017-7559 | — | >= 1.4.0, < 1.4.17.Final | 1.4.17.Final | Jan 10, 2018 | In Undertow 2.x before 2.0.0.Alpha2, 1.4.x before 1.4.17.Final, and 1.3.x before 1.3.31.Final, it was found that the fix for CVE-2017-2666 was incomplete and invalid characters are still allowed in the query string and path parameters. This could be exploited, in conjunction with | ||
