CVE-2024-22770
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-16781 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 vulnerability in Hitron Systems DVR HVR-16781 (versions 1.03 through 4.02) allows remote network-based attacks when the device uses default administrative credentials. The vulnerability stems from insufficient validation of user input in the web interface or API, potentially enabling injection or authentication bypass.

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.
-
Confirm device modelAccess the device administrative interface or check device labeling to verify the model is Hitron HVR-16781Affected if Device is not an HVR-16781 model
-
Check firmware versionAccess the system information or firmware settings in the DVR administrative interface to identify the installed firmware versionAffected if Firmware version is 1.03 through 4.02 (inclusive)
-
Verify credential statusReview or attempt to log in using the default administrative credentials (typically admin/admin or admin/password) to determine if default credentials are still activeAffected if Default factory credentials have not been changed
-
Assess network exposureDetermine if the DVR web interface or API is accessible from untrusted networks by reviewing firewall rules or network configurationAffected if Web interface is exposed to untrusted network segments
User is affected if they have a Hitron HVR-16781 device running firmware between 1.03 and 4.02, with default administrative credentials still in use, and the web interface exposed to the network where the attack could occur.

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 and contact Hitron for firmware updates addressing the input validation flaw; restrict network access to the DVR to trusted IPs if patching is delayed.
Firmware version 4.03 or later
- Identify the current firmware version of the Hitron Systems DVR HVR-16781 device
- Visit the official vendor website at www.hitron.co.kr to download the latest firmware
- Follow the vendor's documented firmware upgrade procedure for the HVR-16781 device
- Verify that the upgraded firmware version is 4.03 or later
- After upgrade, change the default admin credentials to strong, unique passwords to further harden the device
- Confirm the vulnerability is resolved by verifying the device is no longer accepting improper input validation attacks
