CVE-2024-21114
📋 TL;DR
This vulnerability in Oracle VM VirtualBox allows a low-privileged attacker with local access to the host system to compromise the VirtualBox software, potentially leading to full system takeover. It affects VirtualBox versions prior to 7.0.16. The attack can 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 the VirtualBox host system, allowing attacker to execute arbitrary code, access all virtual machines, and potentially pivot to other systems.
Likely Case
Attacker gains elevated privileges on the host system, compromising confidentiality and integrity of virtual machines and host data.
If Mitigated
With proper access controls and patching, risk is limited to authorized users only, reducing attack surface significantly.
🎯 Exploit Status
Oracle describes this as 'easily exploitable' but requires attacker to have logon access to the infrastructure where VirtualBox executes.
