CVE-2023-28809 — Hikvision Ds-K1T320Efwx Firmware security vulnerability

High CVSS 7.5

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.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
