Description

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to insecure deserialization of user-supplied content. A remote unauthenticated attacker can send a malicious serialized Java object to the listening Java Remote Method Invocation (RMI) service and execute arbitrary shell commands on the device with root privileges.

Remediation

Update to version 9.0.6.
