CVE-2026-8598Network attack vector

Credential disclosure via unauthenticated configuration export

Published May 20, 2026 · Updated May 20, 2026

Authentication bypass in ZKTeco SSC335-GC2063-Face-0b77 Solution before 5.0.1.2.20260421 allows remote attackers to obtain camera credentials. An undocumented configuration-export service listens on a separate network port and returns open-service details and stored camera account credentials without enforcing authentication. Network reachability to that port is sufficient; exposure enables credential theft and access to camera services, while no availability impact is reported.
