CVE-2022-2472
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 Initialization vulnerability in the local server component of EZVIZ CS-C6N-A0-1C2WFR allows a local attacker to read the contents of the memory space containing the encrypted admin password. This issue affects: EZVIZ CS-C6N-A0-1C2WFR versions prior to 5.3.0 build 220428.
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 confidenceImproper initialization in the local server component of EZVIZ CS-C6N-A0-1C2WFR camera firmware allows a local attacker to read uninitialized memory containing the encrypted admin password. This occurs because memory is not properly initialized before use, leaking sensitive credential data to a local attacker.

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 modelLocate the model number on the device label or in the device management interface. Confirm it is EZVIZ CS-C6N-A0-1C2WFR.Affected if Device model is EZVIZ CS-C6N-A0-1C2WFR and firmware version is 5.3.0 exactly.
-
Check firmware versionAccess the camera through its web interface or mobile app and navigate to the device settings or system information section to view the installed firmware version.Affected if Firmware version displayed is exactly 5.3.0.
-
Verify local server accessibilityAttempt to access the local server component on the device from the local network using the device IP address on common ports (such as 80, 443, 8000, or vendor-specific ports).Affected if Local server is accessible from the local network on a device running firmware 5.3.0.
-
Confirm vulnerability scopeThis vulnerability allows reading uninitialized memory through the local server component. The flaw exists in firmware version 5.3.0; later builds (such as 220428 or newer) contain the fix.Affected if Device runs firmware 5.3.0 build earlier than 220428.
You are affected if you have an EZVIZ CS-C6N-A0-1C2WFR camera running firmware version 5.3.0 with local server accessibility.

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 · scopedUpgrade EZVIZ CS-C6N-A0-1C2WFR firmware to version 5.3.0 build 220428 or later. As a local attack vector, restrict physical and local network access to the device.
EZVIZ CS-C6N-A0-1C2WFR firmware 5.3.0 build 220428 or later
- 1. Download the latest firmware version 5.3.0 build 220428 or later from the official EZVIZ support website
- 2. Access the camera's web interface or EZVIZ mobile application
- 3. Navigate to the device settings or firmware upgrade section
- 4. Upload the downloaded firmware file and initiate the upgrade process
- 5. Wait for the upgrade to complete and the device to restart
- 6. Verify the firmware version has been updated successfully
