An attacker can upload a crafted update package to the device. The vulnerable devices then unpack the contents of this package and execute a script without proper authentication or verification. This leads to unauthenticated remote code execution, potentially allowing the attacker to gain complete control over the compromised device. The vulnerability was reported by ICS-CERT and assigned a CVSS v3.1 base score of 8.8, indicating a high severity. Successful exploitation of this vulnerability allows an attacker to perform any action on the device, including stealing data, installing malware, or using the device as a foothold for further attacks on the network.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies an Anviz CX2 Lite or CX7 device accessible on the network.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious update package containing a script designed for remote code execution.\u003c/li\u003e\n\u003cli\u003eThe attacker uploads the malicious update package to the device\u0026rsquo;s update interface.
