Vulnerability Data

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and quoting handling to prevent injection flaws.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect quote-injection but does not itself implement the fix.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and output encoding that directly prevent quote-injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for neutralization of special characters such as quotes.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific quoting-neutralization technique.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper escaping or parameterization, directly eliminating CWE-149.
