CVE-2021-37124
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 · uneditedThere is a path traversal vulnerability in Huawei PC product. Because the product does not filter path with special characters,attackers can construct a file path with special characters to exploit this vulnerability. Successful exploitation could allow the attacker to transport a file to certain path.Affected product versions include:PC Smart Full Scene 11.1 versions PCManager 11.1.1.97.
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 confidencePath traversal vulnerability in Huawei PCManager where the application fails to properly sanitize special characters in file paths. Attackers can craft file paths with traversal sequences (such as ../) to write files to unintended directories, potentially achieving arbitrary file write on the affected system.

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 installed Huawei PCManager versionLocate and retrieve the version information for Huawei PCManager from the system (typically found in Add/Remove Programs, the application's About section, or installation directory metadata)Affected if The installed version is exactly 11.1.1.97
-
Identify installed Huawei Pc Smart Full Scene versionLocate and retrieve the version information for Huawei Pc Smart Full Scene from the system (typically found in Add/Remove Programs, the application's About section, or installation directory metadata)Affected if The installed version is exactly 11.1
-
Compare against affected version rangesVerify that the discovered version matches either 11.1.1.97 (PCManager) or 11.1 (Pc Smart Full Scene) as listed in the affected versionsAffected if The installed version matches one of the exact versions specified in the affected products list
The system is affected if either Huawei PCManager version 11.1.1.97 or Huawei Pc Smart Full Scene version 11.1 is installed, as these versions contain the path traversal vulnerability in file path handling.

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 dataImplement strict input validation on all file path parameters to reject traversal sequences and special characters; restrict file operations to safe, predefined directories; verify Huawei has released a patched version and apply available updates.
