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. At the time of advisory publication no public exploitation of this security vulnerability was known.

The bug was discovered 04/09/2019. The weakness was released 04/17/2019. The identification of this vulnerability is CVE-2019-6568 since 01/22/2019. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 08/29/2023).

The vulnerability was handled as a non-public zero-day exploit for at least 8 days. During that time the estimated underground price was around $5k-$25k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
