'Name' => 'NFR Agent Heap Overflow Vulnerability',
'Description' => %q{
This module exploits a heap overflow in NFRAgent.exe, a component of Novell
File Reporter (NFR). The vulnerability occurs when handling requests of name "SRS",
where NFRAgent.exe fails to generate a response in a secure way, copying user
controlled data into a fixed-length buffer in the heap without bounds checking.
This module has been tested against NFR Agent 1.0.4.3 (File Reporter 1.0.2).

* Static analysis
1) Handling of "SRS" records happens in handle_SRS_sub_4048D0:
.text:00404BE9 add esp, 0Ch
.text:00404BEC push 14h ; length_arg_C
.text:00404BEE lea eax, [ebp+record_name_var_28]

.text:00404C15 push eax ; char *
.text:00404C16 call _strcmp ; compares the contents of the "NAME" element in the xml message from the request with the "SRS" string.
.text:00404C1B add esp, 8
.text:00404C1E test eax, eax
.text:00404C20 jnz short loc_404C38 ; if not "SRS" name check others, if yes, handle it...

2) In this function memory is allocated to store the response which will be build:

3) The SRS record used in this module is handled by:
.text:004082E0 ; int __stdcall SRS_7_4_sub_4082E0(char *xml_message_arg_0, char
*result_response_arg_4)
4) The handling function allow to overflow the heap buffer when a big number of VOL elements are processed:
for ( vol_object_var_254 = v25; vol_object_var_254; vol_object_var_254 = *(_DWORD
*)(vol_object_var_254 + 12) )
{
parse_tag_sub_40A760((void *)v15, *(const char **)vol_object_var_254, (int)"VOL",
&vol_name_var_20c, 0x1F4u); // get VOL element
volume_fspace_vol_35C = handle_volume_sub_4081E0(&vol_name_var_20c); // Retrieve Volume
Free Space
volume_fscape_var_358 = v2;
vol_name_html_encode_var_494 = html_encode_sub_40B490(&vol_name_var_20c); // HTML Encode
the volume name (user controlled data)
if ( vol_name_html_encode_var_494 )
{ // If the volume name has been HTML Encoded
v3 = volume_fscape_var_358;
v4 = volume_fspace_vol_35C;
v5 = vol_name_html_encode_var_494;
v6 = strlen(result_response_arg_4);
sprintf(&result_response_arg_4[v6], "<VOL><NAME>%s</NAME><FSPACE>%I64d</FSPACE></VOL>",
v5, v4, v3); // Vulnerability!!! sprintf user controlled data (volume name) to the end of the
fix-length buffer in the heap without bound checking
free(vol_name_html_encode_var_494);
vol_name_html_encode_var_494 = 0;
}
else
{ // If the volume name hasn’t been HTML Encoded
v7 = volume_fscape_var_358;
v8 = volume_fspace_vol_35C;
v9 = strlen(result_response_arg_4);
sprintf(
&result_response_arg_4[v9], // Vulnerability!!! sprintf user controlled data (volume
name) to the end of the fix-length buffer in the heap without bound checking
"<VOL><NAME>%s</NAME><FSPACE>%I64d</FSPACE></VOL>",
&vol_name_var_20c,
v8,
v7);
}
}
The results for every volume (VOL element) are attached to the fixed-length heap buffer via the sprintf at 004085C5:
