The vulnerability allows unauthenticated attackers to send POST requests that modify debug settings on the devices. A successful exploit can enable features like SSH, which are normally restricted. This unauthorized configuration change could be leveraged to gain unauthorized access to the device and potentially the network it is connected to, allowing for further malicious activity. The vulnerability was disclosed in April 2026 and poses a significant risk to organizations using the affected Anviz devices for access control.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies an Anviz CX2 Lite or CX7 device on the network.\u003c/li\u003e\n\u003cli\u003eThe attacker sends an unauthenticated POST request to the device\u0026rsquo;s web interface.\u003c/li\u003e\n\u003cli\u003eThe POST request targets a specific endpoint responsible for modifying debug settings.\u003c/li\u003e\n\u003cli\u003eThe request includes parameters that enable debug features, such as SSH.\u003c/li\u003e\n\u003cli\u003eThe device improperly processes the request without requiring authentication, modifying the debug settings accordingly.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the newly enabled SSH service to gain shell access to the device.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the gained access to escalate privileges, move laterally within the network, or exfiltrate sensitive information.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-40461 allows an attacker to modify device settings, potentially enabling unauthorized access and control over Anviz CX2 Lite and CX7 devices.
