Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input in the Secure Sockets Layer (SSL) VPN feature. A remote attacker can send a specially crafted HTTP request and execute arbitrary code on the target device or cause the device to reload, resulting in a denial of service (DoS) condition.
Mitigation
Install updates from vendor's website.
