CVE-2025-0834
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 · uneditedPrivilege escalation vulnerability has been found in Wondershare Dr.Fone version 13.5.21. This vulnerability could allow an attacker to escalate privileges by replacing the binary ‘C:\ProgramData\Wondershare\wsServices\ElevationService.exe’ with a malicious binary. This binary will be executed by SYSTEM automatically.
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 confidenceA privilege escalation vulnerability exists in Wondershare Dr.Fone 13.5.21 where an attacker with filesystem write access can replace the ElevationService.exe binary at C:\ProgramData\Wondershare\wsServices\ with a malicious executable. Since this service runs with SYSTEM privileges, the replacement binary will execute with highest privileges automatically.

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.
-
Verify Dr.Fone version installedCheck the installed version of Wondershare Dr.Fone by reviewing uninstall entries in Windows Registry (HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\) or look for Dr.Fone in Programs and Features. Compare against version 13.5.21.Affected if Version is 13.5.21 exactly, or falls within an unknown range around this version if additional advisory data becomes available.
-
Confirm vulnerable directory existsVerify that C:\ProgramData\Wondershare\wsServices\ directory exists on the system using File Explorer or command: dir C:\ProgramData\Wondershare\wsServices\Affected if The directory C:\ProgramData\Wondershare\wsServices\ exists on the system.
-
Check for ElevationService.exe presenceList contents of the wsServices directory to confirm ElevationService.exe is present: dir C:\ProgramData\Wondershare\wsServices\ElevationService.exeAffected if ElevationService.exe file exists in the wsServices directory.
-
Inspect directory permissionsRight-click the wsServices folder, go to Properties > Security, and review which users/groups have Write or Modify permissions. Use icacls C:\ProgramData\Wondershare\wsServices\ from command prompt for detailed ACL output.Affected if Users other than Administrators or SYSTEM have Write or Modify permissions on this directory.
A system is affected if Dr.Fone version 13.5.21 is installed and the C:\ProgramData\Wondershare\wsServices\ directory grants write access to non-admin users, allowing potential replacement of ElevationService.exe for privilege escalation.

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 dataRestrict write permissions on the C:\ProgramData\Wondershare\wsServices\ directory to prevent unauthorized binary replacement, or upgrade to a patched version of Dr.Fone if available.
