CVE-2023-36479Network attack vector

Command execution via malformed CGI path quoting

Published Sep 15, 2023 · Updated Jun 18, 2025

Command injection in Eclipse Jetty CgiServlet allows remote authenticated users to execute an unintended server-side binary via a crafted path. The servlet wraps a space-containing path in quotes and passes the string to Runtime.exec, letting an embedded quote-space sequence split it into multiple tokens. The CgiServlet must be deployed; disabling useFullPath removes its existence check and expands the directory layouts that expose the behavior.
