CVE-2024-23907
📋 TL;DR
This vulnerability in Intel High Level Synthesis Compiler allows authenticated local users to escalate privileges by manipulating the search path. It affects users running vulnerable versions of the compiler software on their systems. Attackers could potentially gain higher privileges than intended.
💻 Affected Systems
- Intel High Level Synthesis Compiler
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Authenticated attacker gains full system administrator/root privileges, compromising the entire system and potentially accessing sensitive data or installing persistent malware.
Likely Case
Authenticated user with limited privileges gains elevated access to install software, modify system configurations, or access restricted files.
If Mitigated
With proper access controls and monitoring, impact is limited to isolated systems with no critical data exposure.
🎯 Exploit Status
Exploitation requires local authenticated access and knowledge of search path manipulation techniques.
🛠️ Fix & Mitigation
