Description

Improper input validation in Mort Bay Jetty

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.
