Missing Authorization in Digiever DS‑2105 Pro (CVE‑2023‑52163) Enables Command Injection
What It Is – The Digiever DS‑2105 Pro network video recorder suffers a missing‑authorization flaw in the time_tzsetup.cgi endpoint. An unauthenticated attacker can invoke arbitrary system commands via crafted input.
Exploitability – Publicly disclosed in the CISA Known Exploited Vulnerabilities (KEV) catalog; proof‑of‑concept code is available, indicating active exploitation risk.
Affected Products – Digiever DS‑2105 Pro (all firmware versions prior to the vendor’s pending fix).
Why It Matters for Trust & Control Assurance
- Demonstrates the need for robust access control checks on all management interfaces, a core control objective that maps to multiple frameworks (e.g., NIST CSF, ISO 27001).
- Continuous monitoring of privileged‑access logs provides defensible evidence that unauthorized commands are not occurring.
- Evidence of timely patching and configuration validation is a key audit artifact for customers demanding a verifiable security posture.
Recommended Actions
- Apply Digiever’s security patch as soon as it is released; verify the fix in a test environment.
- Enforce authentication and least‑privilege access on all CGI endpoints; block unused management ports at the network perimeter.
- Deploy continuous log collection for the device’s web interface and integrate alerts into your SIEM.
- Document the remediation steps in your control evidence repository to support audit readiness.
