CVE-2023-28809: Hikvision ds-k1t320efwx firmware improper access control vulnerability

Hikvision · Ds K1t320efwx Firmware

Some access control products are vulnerable to a session hijacking attack because the product does not update the session ID after a user successfully logs in. To exploit the vulnerability, attackers have to request the session ID at the same time as a valid user logs in, and gain device operation permissions by forging the IP and session ID of an authenticated user.
