CVE-2023-41961
📋 TL;DR
This vulnerability in Intel GPA software allows authenticated local users to escalate privileges by manipulating the software's search path. It affects systems running vulnerable versions of Intel GPA software where users have local access.
💻 Affected Systems
- Intel(R) Graphics Performance Analyzers (GPA)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains full administrative/root privileges on the system, potentially compromising the entire machine.
Likely Case
Local authenticated users escalate to higher privileges, enabling them to install malware, access sensitive data, or modify system configurations.
If Mitigated
With proper access controls and patching, the risk is limited to authorized users who already have some level of system access.
🎯 Exploit Status
Exploitation requires local authenticated access and knowledge of the system's file structure.
