Description

The vulnerability allows a remote attacker to execute arbitrary code on the target device.

The vulnerability exists due to a boundary error in the login page at "/cgi-bin/wlogin.cgi" script within the web management interface. A remote attacker can send a specially crafted base64-encoded payload via HTTP POST request to the affected script, trigger memory corruption and execute arbitrary code on the device.


Mitigation

Install updates from vendor's website. As a temporary solution disable access to the web management interface.
