VCID-9xw3-4a4u-hbbb Aliases: CVE-2023-26049 GHSA-p26g-97m4-6q7c	Exposure of Sensitive Information to an Unauthorized Actor 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. So, a cookie header such as: `DISPLAY_LANGUAGE="b; JSESSIONID=1337; c=d"` will be parsed as one cookie, with the name DISPLAY_LANGUAGE and a value of b; JSESSIONID=1337; c=d instead of 3 separate cookies. This has security implications because if, say, JSESSIONID is an HttpOnly cookie, and the DISPLAY_LANGUAGE cookie value is rendered on the page, an attacker can smuggle the JSESSIONID cookie into the DISPLAY_LANGUAGE cookie and thereby exfiltrate it. This is significant when an intermediary is enacting some policy based on cookies, so a smuggled cookie can bypass that policy yet still be seen by the Jetty server or its logging system. This issue has been addressed in versions 9.4.51, 10.0.14, 11.0.14, and 12.0.0.beta0 and users are advised to upgrade. There are no known workarounds for this issue.	There are no reported fixed by versions.
VCID-q3k2-1x5q-buhy Aliases: CVE-2023-40167 GHSA-hmr7-m48g-48f6	Improper Handling of Length Parameter Inconsistency Jetty is a Java based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepts the `+` character proceeding the content-length value in a HTTP/1 header field. This is more permissive than allowed by the RFC and other servers routinely reject such requests with 400 responses. There is no known exploit scenario, but it is conceivable that request smuggling could result if jetty is used in combination with a server that does not close the connection after sending such a 400 response. Versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1 contain a patch for this issue. There is no workaround as there is no known exploit scenario.	There are no reported fixed by versions.
VCID-thpu-76e5-j3d3 Aliases: CVE-2023-36479 GHSA-3gh6-v5v9-6v9j	Jetty vulnerable to errant command quoting in CGI Servlet If a user sends a request to a `org.eclipse.jetty.servlets.CGI` Servlet for a binary with a space in its name, the servlet will escape the command by wrapping it in quotation marks. This wrapped command, plus an optional command prefix, will then be executed through a call to Runtime.exec. If the original binary name provided by the user contains a quotation mark followed by a space, the resulting command line will contain multiple tokens instead of one. For example, if a request references a binary called file” name “here, the escaping algorithm will generate the command line string “file” name “here”, which will invoke the binary named file, not the one that the user requested. ```java if (execCmd.length() > 0 && execCmd.charAt(0) != '"' && execCmd.contains(" ")) execCmd = "\"" + execCmd + "\""; ```	There are no reported fixed by versions.
