Jetty is a java based web server and servlet engine. Nonstandard cookie parsing in Jetty may allow an attacker to smuggle cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie parsing mechanism. If Jetty sees a cookie VALUE that starts with " (double quote), it will continue to read the cookie string until it sees a closing quote – even if a semicolon is encountered. …

Jetty is a java based web server and servlet engine. In affected versions servlets with multipart support (e.g. annotated with @MultipartConfig) that call HttpServletRequest.getParameter() or HttpServletRequest.getParts() may cause OutOfMemoryError when the client sends a multipart request with a part that has a name but no filename and very large content. This happens even with the default settings of fileSizeThreshold=0 which should stream the whole part content to disk. An attacker …

In Eclipse Jetty to alpha0 to alpha0 to, CPU usage can reach % upon receiving a large invalid TLS frame.

In Eclipse Jetty v20210219 to v20210224, the default compliance mode allows requests with URIs that contain %2e o`` %2e%2esegments to access protected resources within the WEB-INF directory. For example a request to/context/%2e/WEB-INF/web.xmlcan retrieve theweb.xml` file. This can reveal sensitive information regarding the implementation of a web application.

In Eclipse Jetty to beta2 to beta2 to, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory.

When Jetty handles a request containing multiple Accept headers with a large number of quality (i.e., q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values.

In Eclipse Jetty on Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including …

Transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. A large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to …
