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 · unedited
Improper Input Validation in Hitron Systems DVR HVR-8781 1.03~4.02 allows an attacker to cause network attack in case of using defalut admin ID/PW.

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 · moderate confidence

Improper input validation in Hitron Systems DVR HVR-8781 (versions 1.03-4.02) allows remote network-based exploitation when the device uses default administrative credentials. The specific input validation flaw in the web interface or API permits an attacker to manipulate input fields to conduct network attacks.

MitigationImmediately change default admin credentials on affected devices and restrict network access to the DVR management interface through firewall rules or network segmentation to limit exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the DVR web interface or check device documentation/labels to confirm the model is Hitron HVR-8781
    Affected if Device is not an HVR-8781 model
  2. Check the installed firmware version
    Log into the DVR web interface and navigate to the System or About section to view the firmware version, or check via API endpoint if available
    Affected if Firmware version is >= 1.03 and < 4.03 (versions 1.03 through 4.02 are affected)
  3. Verify credential configuration
    Check if the device is still using default administrative credentials (typically admin/admin or admin/password) by attempting to log in or reviewing authentication settings
    Affected if Default credentials have not been changed - this is required for the vulnerability to be exploitable
  4. Assess network exposure of the web interface
    Determine if the DVR web interface is accessible from untrusted networks by checking firewall rules, port forwarding, or network segmentation configuration
    Affected if The web management interface is exposed to untrusted networks without firewall protection

The environment is affected if it contains a Hitron HVR-8781 DVR running firmware version 1.03 to 4.02 that still uses default administrative credentials and has its web interface exposed to the network.

Upgrade available Upgrade to 4.03 or later
Fixed in 4.03
Interim mitigation

Immediately change default admin credentials on affected devices and restrict network access to the DVR management interface through firewall rules or network segmentation to limit exposure.

Recommended fix Moderate confidence

Firmware version 4.03 or later

  1. 1. Download the latest firmware version 4.03 or higher from the official Hitron Systems support page (www.hitron.co.kr)
  2. 2. Access the DVR HVR-8781 administration interface
  3. 3. Navigate to the firmware upgrade section in the system settings
  4. 4. Upload and apply the firmware version 4.03 or later
  5. 5. After the upgrade completes, verify the firmware version has been updated successfully
  6. 6. Change the default admin password to a strong, unique password to further harden the device
