Privilege escalation via authenticated path traversal
Published Oct 15, 2025 · Updated Oct 15, 2025
Authorization bypass in Dahua IPC and SD firmware built before July 1, 2025 allows remote authenticated users to read admin-only data. A low-privileged HTTP request traverses paths to read a file holding password-recovery secrets, from which an administrator recovery token can be derived. A normal operator or viewer account is required; the token permits an administrator-password reset, while systems with only an administrator account are unaffected.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=Affected products include certain models from the IPC-1XXX, IPC-2XXX, IPC-WX, and IPC-ECXX series, and limited to versions which build time prior to 1st July 2025 (not including 1st July 2025).
