Netgear DGN2200v1/v2/v3/v4 - 'dnslookup.cgi' Remote Command Execution
Код:
#!/usr/bin/python

#Provides access to default user account, privileges can be easily elevated by using either:
# - a kernel exploit (ex. memodipper was tested and it worked)
# - by executing /bin/bd (suid backdoor present on SOME but not all versions)
# - by manipulating the httpd config files to trick the root user into executing your code (separate advisory will be released soon)
 
#Pozdrawiam: Kornela, Komara i Sknerusa

#You can change these credentials to ex. Gearguy/Geardog or Guest/Guest which are hardcoded on SOME firmware versions
#These routers DO NOT support telnet/ssh access so you can use this exploit to access the shell if you want to
