A path traversal vulnerability in the iclock API of ZKTeco BioTime v8.5.5 allows unauthenticated attackers to read arbitrary files via supplying a crafted payload. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Actively exploited in the wild (cisa kev) and public exploit code available.
Hard-coded cryptographic keys shipped inside ZKTeco BioTime 9.5.6 Build 20260130.3206 can be recovered by anyone with access to the application binary, installer, or firmware, and then reused against a network-exposed BioTime service with no authentication and no user interaction required (CVSS:3.1 AV:N/AC:L/PR:N/UI:N, Low confidentiality/integrity/availability impact). The vendor-reported CVSS 4.0 base score is 6.9, the disclosure originates from a single source (VulDB), and there is no CISA KEV listing and no public exploit identified at time of analysis; because the report does not identify which feature or data the key protects, realistic impact cannot be confirmed and only version 9.5.6 Build 20260130.3206 is named as affected. Attackers must still be able to obtain the binary/firmware containing the key and reach a BioTime service that actually relies on it before any of the Low-severity impact materializes.
Authorization bypass in ZKTeco BioTime 9.5.6 Build 20260130.3206 allows an authenticated low-privilege user to read personnel records outside their authorization scope through the Employee REST API at /personnel/api/employees/. Exploitation requires a valid session (CVSS PR:L) and network reachability to the BioTime web/REST interface, and the resulting impact is confined to confidentiality of employee data (VC:L) with no integrity or availability effect. No public exploit code has been identified at time of analysis, no EPSS or CISA KEV data was provided, and the vendor was contacted about the disclosure but did not respond, so no vendor-released patch is identified at time of analysis.
Authorization bypass in ZKTeco BioTime 9.5.6 Build 20260130.3206 lets an authenticated low-privilege user read biometric records belonging to other employees by manipulating the emp_code argument on the /iclock/finger_data/ Biometric Data Endpoint. Impact is confined to confidentiality of biometric data (assessed CVSS 3.1 5.3, PR:L, C:L, no integrity or availability effect) and requires the BioTime web interface to be network-reachable; no public exploit code identified at time of analysis, the issue is not confirmed actively exploited (CISA KEV), and the risk is assessed as genuine but moderate rather than an urgent priority. The vendor was contacted early about the disclosure and did not respond, so no fixed build is known.
ZKTeco BioTime 9.5.6 Build 20260130.3206 exposes its System Settings API at /base/api/systemSettings to improper access controls, allowing a remote attacker who already holds valid low-privilege credentials to retrieve sensitive system settings due to a CWE-284 authorization flaw. The vulnerability carries a CVSS 4.0 base score of 5.3 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N) and is not known to be actively exploited or to have public exploit code at the time of analysis. Note the discrepancy between the 'Authentication Bypass' tag and the PR:L vector: the assessed impact is limited to confidentiality of system settings, with no integrity or availability impact, making this a low-to-moderate priority issue despite the tag.
