In ZKTeco ZKBio CVSecurity v6.1.1_R and earlier (fixed in 6.1.3_R) an authenticated user can bypass password checks while exporting data from the application.

An issue in ZKTeco BioTime v.8.5.4 and before allows a remote attacker to obtain sensitive information.

An issue in ZKTeko BioTime v.8.5.4 and before allows a remote attacker to obtain sensitive information via the Authentication & Authorization component

A vulnerability was found in ZKTeco ZKBio Media 2.0.0_x64_2024-01-29-1028. It has been classified as problematic. Affected is an unknown function of the file /pro/common/download of the component Service Port 9999. The manipulation of the argument fileName with the input ../../../../zkbio_media.sql leads to path traversal: '../filedir'. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.1.3 Build 2025-05-26-1605 is able to address this issue. It is recommended to upgrade the affected component.

ZKteco ZKBio WDMS before 9.0.2 Build 20250526 allows an attacker to download a database backup via the /files/backup/ component because the filename is based on a predictable timestamp.

A vulnerability was determined in ZKTeco ZKBio Access IVS up to 3.3.2. This impacts an unknown function of the component Department Name Search Bar. This manipulation with the input <marquee>hi causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. The vendor explains: "ZKBio Access IVS is no longer maintained and the product has been replaced by ZKBio CVAccess, it is recommended to replace it with the latest version of ZKBio CVAccess."
