Description
The webserver of the affected devices contains a vulnerability that may lead to
a denial of service condition. An attacker may cause a denial of service
situation which leads to a restart of the webserver of the affected device.
The security vulnerability could be exploited by an attacker with network
access to the affected systems. Successful exploitation requires no system
privileges and no user interaction. An attacker could use the vulnerability
to compromise availability of the device.
