In June 2024, Kaspersky Labs identified in ZKTeco's hybrid biometric access systems. These vulnerabilities span multiple categories:
If you are locked out or setting up for the first time, try these default credentials: : 1234 or 8888 Web 3.0 Login : Username administrator , Password 123456 Gateway IP : 192.168.1.201 (typical) or 192.168.82.1
However, a common search term that brings many IT administrators and facility managers to Google is zkteco keycode generator
Some standalone locks have a limit (e.g., 100 codes). Clear old users if you cannot add new ones.
According to Kaspersky's Georgy Kiguradze, "Attackers can sell stolen biometric data on the dark web, subjecting affected individuals to increased risks of deepfake and sophisticated social engineering attacks". Exploitation of these flaws can also allow bypassing authentication, deploying backdoors, and gaining physical access to restricted areas. In June 2024, Kaspersky Labs identified in ZKTeco's
Firmware updates frequently contain critical security patches. Organizations should establish a regular update schedule for all ZKTeco devices and subscribe to security advisories from ZKTeco.
This occurs if the system date and time on your server do not match the time on the ZKTeco hardware terminal. Sync both devices to the same NTP server and try generating the code again. Organizations should establish a regular update schedule for
A significant vulnerability (CVE-2025-45746) was discovered in ZKT ZKBio CVSecurity 6.4.1_R, where an unauthenticated attacker can craft a JWT token using a hardcoded secret to authenticate to the service console. This vulnerability has been assigned a CVSS base score of 9.8 (CRITICAL) in some assessments, while ZKTeco disputes the significance, arguing that the console is typically only accessible from a local area network and that access to the console does not necessarily grant login or data access within the application software platform.
The software will send an instant command packet to the device over port 4370. Step 3: Access the Device
