HP NNM CGI webappmon.exe OvJavaLocale Buffer Overflow

This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53. By sending a request continaing a cookie longer than 5120 bytes, an attacker can overflow a stack buffer and execute arbitrary code. The vulnerable code is within the OvWwwDebug function. The static-sized stack buffer is declared within this function. When the vulnerability is triggered, the stack trace looks like the following: #0 ... #1 sprintf_new(local_stack_buf, fmt, cooke); #2 OvWwwDebug(" HTTP_COOKIE=%s\n", cookie); #3 ?OvWwwInit@@YAXAAHQAPADPBD@Z(x, x, x); #4 sub_405ee0("nnm", "webappmon"); No validation is done on the cookie argument. There are no stack cookies, so exploitation is easily achieved by overwriting the saved return address or SEH frame. The original advisory detailed an attack vector using the "OvJavaLocale" cookie being passed in a request ot "webappmon.exe". Further research shows that several different cookie values, as well as several different CGI applications, can be used. '
