CVE-2025-61760
📋 TL;DR
This vulnerability in Oracle VM VirtualBox allows a low-privileged attacker with local access to the host system to potentially take over VirtualBox through a difficult-to-exploit attack requiring human interaction from another user. It affects VirtualBox versions 7.1.12 and 7.2.2. The attack could impact additional products beyond VirtualBox itself due to scope change.
💻 Affected Systems
- Oracle VM VirtualBox
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of Oracle VM VirtualBox leading to potential host system compromise, data exfiltration, and lateral movement to other systems.
Likely Case
Local privilege escalation within VirtualBox environment, potentially allowing attacker to escape guest VM isolation and access host resources.
If Mitigated
Limited impact due to required human interaction and local access constraints, with proper segmentation preventing lateral movement.
🎯 Exploit Status
Exploitation is difficult, requires low privileged attacker with local access, human interaction from another person, and specific conditions. No public exploit available as of analysis.
