Description Tomas Hoger 2009-11-03 08:03:03 EST
ush.it reported multiple flaws affecting jetty 6.x and 7.x:


Issues reported include:

 E) "Cookie Dump Servlet" escape sequence injection
    (Affected versions: Any)

 F) Http Content-Length header escape sequence injection
    (Affected versions: Any)

An attacker-supplied input containing special characters may be copied to stack traces printed to jetty log when exception is raised due to some problem with parsing user input (non-numeric Max-Age value in case of demo Cookie servlet (E) or non-numeric Content-Length HTTP header value (F)).  When log file is later viewed in a terminal that understands special escape sequences (most graphical terminal emulators), those escape sequences may cause terminal to run an arbitrary command.
