CVE-2024-7834
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 · uneditedA local privilege escalation is caused by Overwolf loading and executing certain dynamic link library files from a user-writeable folder in SYSTEM context on launch. This allows an attacker with unprivileged access to the system to run arbitrary code with SYSTEM privileges by placing a malicious .dll file in the respective location.
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 confidenceOverwolf launches with SYSTEM privileges and loads dynamic link library files from a user-writeable folder path. An unprivileged attacker can place a malicious DLL in this location, which Overwolf will then execute in SYSTEM context, achieving privilege escalation to full system control.

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 Overwolf is installedCheck for Overwolf installation by searching common paths such as Program Files and Program Files (x86), and checking registry keys under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Overwolf entriesAffected if Overwolf is found installed on the system
-
Check installed version against affected rangeLocate the main Overwolf executable (typically overwolf.exe or similar) and retrieve its file version property. Compare this version number to 250.1.1Affected if The installed version is lower than 250.1.1 (the first digit before the decimal is the major version)
-
Confirm Overwolf runs with SYSTEM privilegesCheck the Overwolf service configuration in Windows Services (services.msc) or examine the process token when Overwolf is running to verify it executes with SYSTEM or elevated privilegesAffected if Overwolf runs as SYSTEM or with administrator-level privileges
-
Identify DLL loading paths used during startupUse process monitoring tools (such as Process Monitor from Sysinternals) to observe which folder paths Overwolf accesses when loading dynamic link libraries during startupAffected if Overwolf loads DLLs from paths that standard users can write to
A system is affected if Overwolf version is below 250.1.1, runs with SYSTEM privileges, and loads DLLs from user-writeable folder paths during startup

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.
dbcve · scoped250.1.1
Apply vendor patches from Overwolf that enforce secure DLL loading from trusted locations only. Until patched, restrict or monitor write access to folders from which Overwolf loads DLLs during startup.
250.1.1
- Navigate to the official Overwolf website and download the latest version of the Overwolf client
- Install or update to the latest available version of Overwolf
- Verify the installed version is 250.1.1 or higher by checking the application's About or Settings section
