"It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2394 advisory.
- Eclipse Jetty Canonical Repository is the canonical repository for the Jetty project. Users of the
CgiServlet with a very specific command structure may have the wrong command executed. 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. This issue was patched in version 9.4.52, 10.0.16, 11.0.16 and 12.0.0-beta2.
