CVE-2019-9682 — Dahuasecurity Sd6Al Firmware security vulnerability

High CVSS 8.1

Dahua devices with Build time before December 2019 use strong security login mode by default, but in order to be compatible with the normal login of early devices, some devices retain the weak security login mode that users can control. If the user uses a weak security login method, an attacker can monitor the device network to intercept network packets to attack the device. So it is recommended that the user disable this login method.

Privilege escalation and unsafe privilege management

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

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
