CVE-2019-5263
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 · uneditedHiSuite with 9.1.0.305 and earlier versions and 9.1.0.305(MAC) and earlier versions and HwBackup with earlier versions before 9.1.1.308 have a brute forcing encrypted backup data vulnerability. Huawei smartphone user backup information can be obtained by brute forcing the password for encrypting the backup.
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 confidenceHuawei's HiSuite and HwBackup backup tools have a vulnerability where encrypted backup data can be brute-forced to recover the encryption password. An attacker with access to the backup files could systematically try password candidates to decrypt the backup and obtain user data.

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 HiSuite version on WindowsOpen Control Panel > Programs and Features, or navigate to the HiSuite installation directory (typically C:\Program Files\Huawei\HiSuite) and locate the version information in the properties of the executable file.Affected if The installed version is 9.1.0.305 or lower.
-
Check HwBackup versionOpen HwBackup application and navigate to Settings > About, or check the installed version in Windows Programs and Features if it's a Windows application.Affected if The installed version is 9.1.1.308 or lower.
-
Identify if backup files existSearch for .db, .backup, or backup-related file extensions in common backup storage locations such as the HiSuite default backup folder (typically in the user's Documents or a designated backup folder).Affected if Encrypted backup files created by these tools exist on the system.
-
Verify encryption protection strengthThis requires access to the backup file structure to assess whether the encryption implementation uses weak key derivation. This is typically not directly verifiable without technical analysis tools.Affected if Unable to verify strong encryption protection is in place (version-based check is the primary indicator).
A user is affected if HiSuite version 9.1.0.305 or lower, or HwBackup version 9.1.1.308 or lower, is installed and has created backup files that could be subject to brute-force attacks.

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.
From vendor dataUpdate HiSuite to a version after 9.1.0.305 and HwBackup to version 9.1.1.308 or later to obtain the patched software with improved brute-force protection.
