CVE-2026-56808
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDGM3103SCT provided by AVTECH Security Corporation contains an OS command injection vulnerability, which may lead to arbitrary command execution with the root privilege by a user who can log in to the web management console of the affected product.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe DGM3103SCT surveillance device from AVTECH Security Corporation contains an OS command injection vulnerability in its web management console. An authenticated attacker can inject arbitrary OS commands through web interface input fields, which are then executed with root privileges on the underlying Linux system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck the physical device label, firmware boot screen, or web interface header for model number DGM3103SCT. Access the device web portal and look for model identification in system information or device status pages.Affected if The device is a DGM3103SCT from AVTECH Security Corporation
-
Confirm web management console is accessibleAttempt to access the device web interface via HTTP/HTTPS on typical ports such as 80, 443, or 8080. Check if the login page or management console loads.Affected if The web management console is reachable on the network
-
Verify authentication is requiredCheck if the web interface requires login credentials before allowing access to management functions. Attempt to access protected pages without credentials to confirm authentication is enforced.Affected if Authentication is NOT required or is easily bypassed, meaning any attacker can reach the injection points
-
Identify input fields in web interfaceLog into the web management console and navigate through settings pages (network configuration, system settings, or similar). Locate text input fields, parameter fields, or configuration options that may accept user-supplied data.Affected if The web interface contains input fields that accept user data and could potentially pass this to system calls
You are affected if you have a DGM3103SCT device with an accessible web management console that either lacks authentication or allows authenticated users to submit input through web fields that could trigger OS command execution.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict web management console access to trusted users only using strong authentication, implement strict input validation and sanitization on all user-supplied parameters before passing them to system calls, and apply vendor patches when available. Consider network segmentation to minimize exposure.
