CVE-2016-20029Public exploit

Local file disclosure via unchecked resource paths

Published Mar 15, 2026 · Updated Mar 15, 2026

File path manipulation in ZKTeco ZKBioSecurity 3.0.1.0_R_230 allows local users to read arbitrary application files. The local-resource retrieval path accepts attacker-controlled path components without enforcing the intended file-access boundary. Local access to the Windows host is required, and published assessments report confidentiality impact without file modification or service interruption.
