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
Bashis, a Security Researcher at IPVM has found a flaw that allows for a remote code execution during the installation of Wave on the camera device. The Wave server application in camera device was vulnerable to command injection allowing an attacker to run arbitrary code. HanwhaVision has released patched firmware for the highlighted flaw. Please refer to the hanwhavision security report for more information and solution."

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

A command injection vulnerability in the Wave server application on HanwhaVision camera devices allows remote attackers to execute arbitrary code during the installation process. The vulnerability stems from improper input validation in the Wave component, enabling malicious command injection that can lead to complete device compromise.

MitigationApply the patched firmware released by HanwhaVision to all affected camera devices. For devices that cannot be immediately updated, network segmentation and restricting access to the camera management interfaces can reduce exposure until patching is feasible.

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 Wave Server Software version
    Access the HanwhaVision device management interface or check the installed Wave Server Software version through the system information or about section. Compare the version number to the affected range: versions prior to 5.1.1.37647 are vulnerable.
    Affected if Wave Server Software version is less than 5.1.1.37647
  2. Identify the camera firmware version for Pno A6081r E1t
    Access the camera web interface or use the device's firmware check feature. Navigate to the firmware or system information page to view the installed firmware version.
    Affected if Firmware version on Pno A6081r E1t equals exactly 2.21.02
  3. Identify the camera firmware version for Pno A6081r E2t
    Access the camera web interface or use the device's firmware check feature. Navigate to the firmware or system information page to view the installed firmware version.
    Affected if Firmware version on Pno A6081r E2t equals exactly 2.21.02
  4. Verify if the Wave server component is installed
    Check the device or management system for the presence of the Wave server application component. This is typically found in the software feature list or installed applications on the device.
    Affected if The Wave server application is installed and the version cannot be verified as 5.1.1.37647 or higher

A device is affected if it runs Wave Server Software versions below 5.1.1.37647, or if it is a Pno A6081r E1t or E2t camera with firmware version 2.21.02, and the Wave server component is present.

Upgrade available Upgrade to 5.1.1.37647 or later
Fixed in 5.1.1.37647
Interim mitigation

Apply the patched firmware released by HanwhaVision to all affected camera devices. For devices that cannot be immediately updated, network segmentation and restricting access to the camera management interfaces can reduce exposure until patching is feasible.

Recommended fix Moderate confidence

Wave Server Software >= 5.1.1.37647; Camera firmware > 2.21.02 (obtain exact version from HanwhaVision)

  1. Upgrade Wave Server Software to version 5.1.1.37647 or later
  2. For Pno A6081r E1t camera: Apply the patched firmware released by HanwhaVision (version higher than 2.21.02)
  3. For Pno A6081r E2t camera: Apply the patched firmware released by HanwhaVision (version higher than 2.21.02)
  4. After upgrading, verify the Wave server application is functioning correctly and the vulnerability is resolved
  5. Refer to the official HanwhaVision security report for detailed firmware download and installation instructions
