CVE-2020-9100
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 · uneditedEarlier than HiSuite 10.1.0.500 have a DLL hijacking vulnerability. This vulnerability exists due to some DLL file is loaded by HiSuite improperly. And it allows an attacker to load this DLL file of the attacker's choosing.
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 confidenceHiSuite versions earlier than 10.1.0.500 contain a DLL hijacking vulnerability where the application improperly loads DLL files using an insecure method, allowing an attacker to place a malicious DLL in a location where it will be loaded before the legitimate DLL, potentially leading to arbitrary code execution.

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.
-
Find HiSuite installation directorySearch for HiSuite installation folders - common locations include C:\Program Files\Huawei\HiSuite, C:\Program Files (x86)\Huawei\HiSuite, or the user's AppData folder. Also check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for HiSuite entries.Affected if HiSuite is found installed on the system.
-
Locate HiSuite executable and check versionFind the main HiSuite executable (typically HiSuite.exe) in the installation directory. Right-click the file, select Properties, and view the Details tab to see the File Version or Product Version.Affected if The executable exists and version information is available.
-
Compare installed version to affected rangeCompare the found version number to 10.1.0.500. Look for versions displayed as something like 10.x.x.x or earlier version numbers.Affected if The installed version is earlier than 10.1.0.500 (e.g., 9.x.x.x, 8.x.x.x, etc.).
-
Verify DLL loading behaviorSince this is a DLL hijacking vulnerability, examine whether HiSuite runs from directories where non-admin users have write access. Check folder permissions on the HiSuite installation directory and any directories in the application PATH that it uses for loading DLLs.Affected if The application runs from or loads DLLs from directories with weak permissions where an attacker could place a malicious DLL.
The system is affected if HiSuite version is found to be earlier than 10.1.0.500 and the application loads DLLs from directories with writable access for untrusted users.

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 data10.1.0.500
Upgrade HiSuite to version 10.1.0.500 or later, which contains the patch for this vulnerability. If immediate upgrade is not possible, implement application whitelisting and ensure the application runs from trusted directories with restricted write access.
