CVE-2023-3938 is an SQL Injection vulnerability (CWE-89) affecting ZkTeco-based OEM devices, including ZkTeco ProFace X and Smartec ST-FR043/ST-FR041ME, specifically with firmware ZAM170-NF-1.8.25-7354-Ver1.0.0 and potentially others. This flaw allows an unauthenticated attacker with physical access to bypass authentication and log in as any user from the device's database. Rated as MEDIUM severity with a CVSS score of 4.6 (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the vulnerability requires physical proximity but is easy to exploit, leading to high confidentiality impact. There is no impact on integrity or availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog. While it has received some community discussion and media coverage, its EPSS score is very low, suggesting a minimal likelihood of exploitation in the wild.
