| HP JetDirect J3111A Module Denial of Service |
Reported November 19, 1999 by Tobias Haustein
The HP JetDirect J3111A module with firmware G.05.35 suffers from a buffer overflow in it"s internal web server that can lead to a crash, and thus, a denial of service.
By entering the following URL in a Web browser, the printer prints a diagnostics page showing the contents of all registers and the following 64 bytes of all memory addresses that address registers point to.
http://my-printer"s-IP/very-long-rubbish (256 bytes or so)
Tobias did not notify HP of this problem, however, the vendor has been made aware through other channels.
