CVE-2023-28809 is a high-severity session hijacking vulnerability affecting Hikvision access control products. It allows an attacker to gain device operation permissions by simultaneously requesting a session ID during a legitimate user's login and then forging the authenticated user's IP and session ID. The vulnerability has a CVSS score of 7.5 (High) due to its high impact on confidentiality, integrity, and availability, though it requires high attack complexity and user interaction. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
