CVE-2024-31953
📋 TL;DR
This vulnerability allows local attackers with existing user privileges to escalate to administrator privileges through arbitrary code execution during Samsung Magician installation on macOS. Attackers can tamper with installation files to execute malicious code when an administrator password is entered during installation. Only macOS users running Samsung Magician 8.0.0 are affected.
💻 Affected Systems
- Samsung Magician
📦 What is this software?
Magician by Samsung
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full administrator privileges, potentially installing persistent malware, accessing sensitive data, or using the system as a foothold for lateral movement.
Likely Case
Local privilege escalation allowing attacker to bypass security controls, install unauthorized software, or modify system configurations.
If Mitigated
Limited impact if proper access controls prevent unauthorized users from tampering with installation directories and files.
🎯 Exploit Status
Exploitation requires local access, user privileges, and ability to tamper with installation files before administrator authentication occurs.
