'Description' => %q{
|
|
RaspAP is feature-rich wireless router software that just works
|
|
on many popular Debian-based devices, including the Raspberry Pi.
|
|
A Command Injection vulnerability in RaspAP versions 2.8.0 thru 2.8.7 allows
|
|
unauthenticated attackers to execute arbitrary commands in the context of the user running RaspAP via the cfg_id
|
|
parameter in /ajax/openvpn/activate_ovpncfg.php and /ajax/openvpn/del_ovpncfg.php.
|
|
|
|
Successfully tested against RaspAP 2.8.0 and 2.8.7.
