# TrendMicro InterScan Web Security Virtul Appliance  
# ==================================================  
# InterScan Web Security is a software virtual appliance that   
# dynamically protects against the ever-growing flood of web   
# threats at the Internet gateway exclusively designed to secure   
# you against traditional and emerging web threats at the Internet   
# gateway. The appliance however is shipped with a vulnerable  
# version of Bash susceptible to shellshock (I know right?). An  
# attacker can exploit this vulnerability by calling the CGI  
# shellscript "/cgi-bin/cgiCmdNotify" which can be exploited  
# to perform arbitrary code execution. A limitation of this   
# vulnerability is that the attacker must have credentials for  
# the admin web interface to exploit this flaw. The panel runs  
# over HTTP by default so a man-in-the-middle attack could be  
# used to gain credentials and compromise the appliance.  
#   
# $ python trendmicro_IWSVA_shellshock.py 192.168.56.101 admin password 192.168.56.1  
# [+] TrendMicro InterScan Web Security Virtual Appliance CVE-2014-6271 exploit
