Design/Logic Flaw

A vulnerability was found in all versions of Keycloak Gatekeeper, where on using lower case HTTP headers via cURL an attacker can bypass our Gatekeeper. Lower case headers are also accepted by some webservers e.g. Jetty. This means there is no protection when we put a Gatekeeper in front of a Jet...

Operation on a Resource after Expiration or Release in Jetty Server

In Eclipse Jetty, versions 9.4.27.v20200227 to 9.4.29.v20200521, in case of too large response headers, Jetty throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this doub...

Information Disclosure

jetty-server is vulnerable to information disclosure. An HTTP 431 error occurs when large response headers are received, causing the HTTP response headers to be released to ByteBufferPool twice. This results in a double release and memory corruption and causes confidential information to be...

Authorization Bypass

jetty-server is vulnerable to authorization bypass. The vulnerability exists as a buffer corruption could occur when the response buffer is too large, allowing the header buffer to be released, but not nulled, causing the server to send incorrect responses to different clients...

jetty: error path information disclosure

In Eclipse Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older, the server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches...

jetty: full server path revealed when using the default Error Handling

In Eclipse Jetty Server, all 9.x versions, on webapps deployed using default Error Handling, when an intentionally bad query arrives that doesn't match a dynamic url-pattern, and is eventually handled by the DefaultServlet's static file serving, the bad characters can trigger a...

Cross-Site Scripting (XSS)

jetty-server is vulnerable to cross-site scripting. The server response containing the default error message from stacktraces is not sanitized and escaped before being displayed, which would allow a remote attacker to inject arbitrary Javascript into a victim's browser...

DEBIAN-CVE-2019-10247

In Eclipse Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older, the server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches...

UBUNTU-CVE-2018-12545

In Eclipse Jetty version 9.3.x and 9.4.x, the server is vulnerable to Denial of Service conditions if a remote client sends either large SETTINGs frames container containing many settings, or many small SETTINGs frames. The vulnerability is due to the additional CPU and memory allocations require...

CRLF Injection

Jetty Server is vulnerable to CRLF injection. A remote attacker is able to inject arbitrary HTTP headers into the server response to perform response splitting attacks via the reason string in AbstractGenerator.java...

GHSA-6X9X-8QW9-9PP6 Jetty vulnerable to authorization bypass due to inconsistent HTTP request handling (HTTP Request Smuggling)

Eclipse Jetty Server versions 9.2.x and older, 9.3.x all non HTTP/1.x configurations, and 9.4.x all HTTP/1.x configurations, are vulnerable to HTTP Request Smuggling when presented with two content-lengths headers, allowing authorization bypass. When presented with a content-length and a chunked...
