Multiple Flaws in Axesstel MV 410R
by Filip Palian "http://192.168.0.1/cgi-bin/sysconf.cgi?RESTORE=RESTORE" (user
confirmation not needed) will reset device to default configuration.
#10 Permanent XSS
It's possible to plant permanent XSS in the web interface using
"http://192.168.0.1/cgi-bin/sysconf.cgi" script.
#11 Automatic redirection
Some scripts do the automatic redirection after execution. This feature
may be used to hide for example a CSRF attack. evilsite.com leads to
"http://192.168.0.1/cgi-bin/wireless.cgi" where script is executed and
it autoredirects back to evilsite.com.
Status:
At the moment no fixes were provided by the vendor. As a workaround
administrator should:
#1 restrict access to device only from LAN
#2 change the default administrator password (still can be sniffed in LAN)
#3 enable Wi-Fi encryption
#4 turn on clients MAC addresses filtering
#5 turn off SSID broadcasting

to protect themselves against these serious threats before vendor will
realese fixes and before the bad guys will reach them first.
