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 · unedited
Untrusted search path vulnerability in Baidu Browser Version 43.23.1000.500 and earlier allows an attacker to gain privileges via a Trojan horse DLL in an unspecified directory.

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 confidence

DLL hijacking vulnerability in Baidu Browser allows attackers to place malicious DLL files in an unspecified directory that the browser searches for DLLs, enabling arbitrary code execution with the privileges of the user running the browser.

MitigationUpdate Baidu Browser to a version later than 43.23.1000.500, or replace with an alternative browser. As a defensive measure, ensure the browser installation directory and system PATH directories are not writable by untrusted users.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Baidu Spark Browser is installed
    Look for Baidu Spark Browser in the system: Check C:\Program Files\Baidu or C:\Program Files (x86)\Baidu for the Spark folder, or search for 'Spark' in Add/Remove Programs or Programs and Features.
    Affected if Baidu Spark Browser is found on the system.
  2. Identify installed Baidu Spark Browser version
    Navigate to the Baidu Spark Browser installation folder (typically C:\Program Files\Baidu\Spark or C:\Program Files (x86)\Baidu\Spark), right-click the executable file (such as spark.exe or SSpark.exe), select Properties, and view the version number on the Details tab.
    Affected if The displayed version is 43.23.1000.500 or earlier.
  3. Check DLL search path behavior
    Run Baidu Spark Browser while monitoring DLL loading using tools such as Process Monitor (procmon.exe from Sysinternals) to observe which directories the browser searches for DLL files. Filter by process name and look for DLL load events that reference directories outside the browser's own folder.
    Affected if The browser loads DLLs from directories accessible to untrusted users, or the DLL search path includes user-writable locations.
  4. Review file system permissions on browser directory
    Right-click the Baidu Spark Browser installation folder, select Properties, go to the Security tab, and verify which users have Write or Modify permissions on the folder. Also check system PATH directories for write access by untrusted users.
    Affected if The browser installation directory or any PATH directories are writable by users who should not have elevated access.

A user is affected if Baidu Spark Browser version 43.23.1000.500 or earlier is installed and the browser's DLL search path includes directories writable by untrusted users.
