Dahua Sd50 Vulnerabilities
6 known CVEs, 3 critical, 1 in CISA's Known Exploited Vulnerabilities catalog. Last updated 2026-10-24.
Known CVEs
Some Dahua products with Build time before December 2019 have Session ID predictable vulnerabilities. During normal user access, an attacker can use the predicted Session ID to construct a data packet to attack the de...
The identity authentication bypass vulnerability found in some Dahua products during the login process. Attackers can bypass device identity authentication by constructing malicious data packets.
Some Dahua products have access control vulnerability in the password reset process. Attackers can exploit this vulnerability through specific deployments to reset device passwords.
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...
Some Dahua products have buffer overflow vulnerabilities. After the successful login of the legal account, the attacker sends a specific DDNS test command, which may cause the device to go down.
Some products of Dahua have Denial of Service vulnerabilities. After the successful login of the legal account, the attacker sends a specific log query command, which may cause the device to go down.
Commonly exposed ports
- Port 554 (RTSP) — Streams the raw camera feed — if exposed to the internet, anyone who finds it can watch it.
- Port 8000 (Vendor device/mobile-app port) — Used by the vendor’s own mobile app to reach the camera; a frequent target for credential-stuffing.
- Port 37777 (Dahua/Hikvision proprietary port) — Vendor-specific control protocol, often enabled by default and rarely needed from the internet.
- Port 80 (HTTP admin panel) — The web admin UI; dangerous if port-forwarded to the internet.
Default credentials
No verified default-credential pair for this model in ProbeShield's own tested list — check the label on the device or its manual.
Hardening checklist
- Never port-forward the camera directly to the internet — use the vendor’s cloud app or a VPN instead.
- Change the default admin password immediately after setup.
- Disable UPnP on your router so the camera can’t punch its own hole in your firewall.
- Check for a firmware update in the vendor’s app and apply it.
- Turn off any "cloud P2P"/remote-access feature you don’t actually use.
Frequently asked questions
Is my Dahua Sd50 affected by these vulnerabilities? Only if you’re running a firmware version in the affected range listed above and haven’t updated. Check your camera's admin panel for its current firmware version and compare it against the ranges below.
How do I update my Dahua Sd50's firmware? Log into the camera's web admin panel (usually at its local IP address) and look for a Firmware Update or System Update section, or use the vendor's mobile app if it has one.
Does ProbeShield fix these vulnerabilities for me? No — ProbeShield scans your network and tells you what it finds (open ports, default credentials, outdated firmware signals) so you know what to fix, and how. It never changes your devices’ settings.
