Mort Bay Jetty 6.x through 6.1.22 and 7.0.0 writes backtrace data without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator, related to (1) a string value in the Age parameter to the default URI for the Cookie Dump Servlet in test-jetty-webapp/src/main/java/com/acme/CookieDump.java under cookie/, (2) an alphabetic value in the A parameter to jsp/expr.jsp, or (3) an alphabetic value in the Content-Length HTTP header to an arbitrary application.

Security readout for executives and security teams

This old Jetty issue can let a remote request place terminal escape characters into error backtraces. The business risk is operational compromise through unsafe log or console viewing, not normal web content execution. Evidence in the bundle does not show active exploitation. Exposure is likely limited to legacy Jetty 6.x through 6.1.22 or 7.0.0 deployments, especially test webapp endpoints or applications that emit request parsing backtraces to logs or consoles viewed in terminal emulators. Treat as a legacy cleanup and operational hardening item unless affected Jetty versions remain internet-facing. Prioritize remediation for production systems where administrators inspect raw logs in terminals. Mitigation focus: Identify any Mort Bay Jetty 6.x through 6.1.22 or 7.0.0 deployments.; Check Jetty or vendor guidance for fixed releases and supported upgrade paths.; Remove or restrict bundled test webapps and diagnostic JSPs from production..
