CVE-2023-25645 — There is a permission and access control vulnerability in some ZTE AndroidTV STBs

High CVSS 7.7

There is a permission and access control vulnerability in some ZTE AndroidTV STBs. Due to improper permission settings, non-privileged application can perform functions that are protected with signature/privilege-level permissions. Exploitation of this vulnerability could clear personal data and applications on the user's device, affecting device operation.

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.
