Published Dec 17, 2023 · Updated May 7, 2025

Information disclosure in SPON IP Network Intercom Broadcasting System 3.0.3_20201113_RELEASE(HIK) allows remote attackers to read log data. The Log File Handler serves access/html/system.html without enforcing authorization, exposing system log information to unauthenticated requests. An attacker must reach the system on an adjacent network; the published record reports confidentiality loss only, with no write or service-interruption impact.
