CVE-2024-22768
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 · uneditedImproper Input Validation in Hitron Systems DVR HVR-4781 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 confidenceImproper input validation in Hitron Systems DVR HVR-4781 firmware versions 1.03 through 4.02 allows remote attackers to exploit insufficient input sanitization. When default admin credentials are in use, an attacker can send specially crafted network requests that bypass validation checks, potentially enabling injection or unauthorized access attacks.

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 the device modelAccess the DVR administration interface or check the device label to confirm the model is Hitron HVR-4781Affected if the device is not a Hitron HVR-4781, then it is not affected by this specific CVE
-
Check the installed firmware versionLog into the DVR web interface and navigate to the System or Firmware section to view the current firmware version, or use the command-line interface if availableAffected if the firmware version is between 1.03 and 4.02 inclusive (versions 1.03, 1.04, ... 4.01, 4.02) or if the version shows less than 4.03
-
Verify if default admin credentials are in useCheck the user accounts configuration in the DVR administration panel to determine if the default administrator username and password (typically admin/admin or similar factory defaults) are still activeAffected if the default administrator credentials have not been changed from the factory default values
-
Assess network exposure of the DVR deviceReview firewall rules and network configuration to determine if the DVR management interface is accessible from untrusted networks or directly from the internetAffected if the device is reachable from external networks without proper network segmentation or firewall controls
The environment is affected if the device is a Hitron HVR-4781 running firmware version 1.03 through 4.02 with default admin credentials still configured and the device is network-accessible to potential attackers.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped4.03
Change default admin credentials immediately as a first-order mitigation. Contact Hitron Systems for firmware updates addressing the input validation vulnerability, and implement network segmentation to limit exposure of the DVR device.
Firmware 4.03 or later
- Check the current firmware version of the Hitron HVR-4781 DVR device
- Download firmware version 4.03 or later from the official Hitron Systems website (www.hitron.co.kr)
- Follow the manufacturer's published firmware update procedure to apply the upgrade
- After upgrading, change the default admin credentials to prevent exploitation
- Verify the firmware upgrade was successful by checking the version in the device management interface
