CVE-2023-23432
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 · uneditedSome Honor products are affected by signature management vulnerability, successful exploitation could cause the forged system file overwrite the correct system file.
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 confidenceThis is a signature management vulnerability in Honor products where the system fails to properly validate signatures on system files before allowing overwrites. Successful exploitation allows an attacker to replace legitimate system files with forged malicious ones, potentially leading to system compromise or persistent malware.

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.
-
Check device firmware versionNavigate to Settings > About Phone > Version on the Honor device, or run 'getprop ro.build.version.emui' or 'getprop ro.build.version.custom' via ADB shell to retrieve the firmware build numberAffected if The displayed firmware version is less than 7.0.0.157 on a Hihonor Nth An00 model
-
Confirm device modelNavigate to Settings > About Phone > Model Number, or run 'getprop ro.product.model' via ADB shell to verify the exact device modelAffected if The model is Hihonor Nth An00 and the firmware version is below 7.0.0.157
-
Check system file signature verification statusRun 'getprop ro.secureboot.status' via ADB shell to check if secure boot with signature validation is enabled on the deviceAffected if The property returns 'disabled' or signature verification is not enforced (specific output depends on device configuration)
-
Verify OTA update source configurationNavigate to Settings > System & Updates > Software Update > Menu > Settings, or run 'getprop ro.oem.upgrade.selector' via ADB shell to check if only vendor-signed updates are allowedAffected if OTA updates are permitted from non-vendor sources or the upgrade selector is not set to enforce vendor-signed packages only
A user is affected if their Hihonor Nth An00 device runs firmware version 7.0.0.157 or lower, as the signature validation flaw allows unsigned or improperly signed system files to be installed.
