CVE-2025-44612
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTinxy WiFi Lock Controller v1 RF was discovered to transmit sensitive information in plaintext, including control information and device credentials, allowing attackers to possibly intercept and access sensitive information via a man-in-the-middle attack.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Tinxy WiFi Lock Controller v1 RF transmits sensitive control information and device credentials in plaintext over the network. An attacker positioned man-in-the-middle can intercept these credentials and potentially take control of the lock device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelCheck the physical device label, packaging, or the device's admin/web interface for the exact model name and firmware version. Confirm it is a Tinxy WiFi Lock Controller V1 RF.Affected if The device is a Tinxy WiFi Lock Controller V1 RF
-
Capture outbound network trafficPlace a network packet sniffer (such as Wireshark or tcpdump) on the network segment between the Tinxy device and your router/gateway. Capture traffic while the device sends commands or communicates with its backend.Affected if Network traffic capture is possible without decryption requirements
-
Inspect traffic for plaintext credentialsAnalyze the captured packets. Look for HTTP traffic (not HTTPS), unencrypted telnet, or other plaintext protocols. Search the payload for recognizable credential strings, device identifiers, or control command data transmitted without encryption.Affected if Credentials, device IDs, or control commands appear in the packet payload in plaintext (readable human text)
-
Verify encryption protocol usedCheck if the device uses TLS/SSL (HTTPS, WSS, or other encrypted protocols) for its communications. In the captured traffic, look for the TLS handshake (ClientHello, ServerHello) before any authentication data is sent.Affected if The device does not establish a TLS/encrypted session before transmitting sensitive data
If the Tinxy WiFi Lock Controller V1 RF transmits authentication credentials or lock control commands over the network in plaintext without TLS/SSL encryption, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement TLS/SSL encryption for all network communications between the lock controller and backend servers. If the device firmware cannot be updated, consider network segmentation to limit exposure and monitor for suspicious interception attempts.
