CVE-2024-50386
CVE-2024-50386 affects Apache CloudStack, allowing attackers to deploy malicious instances on KVM-based environments. The vulnerability arises from missing validation checks for KVM-compatible templates, potentially leading to host filesystem access. With an SVRS of 36, while not critical, this vulnerability still presents a notable risk. An attacker who can register templates can exploit this to gain unauthorized access, potentially compromising resource integrity and confidentiality. This could result in data loss, denial of service, and overall availability issues for KVM-based infrastructure. Users should upgrade to Apache CloudStack 4.18.2.5 or 4.19.1.3, or later, to mitigate this risk. Furthermore, operators can scan user-registered KVM-compatible templates to ensure they are flat files without unnecessary features.
Description
CVE-2024-50386 is a vulnerability in Apache CloudStack versions 4.0.0 through 4.18.2.4 and 4.19.0.0 through 4.19.1.2. This vulnerability arises from missing validation checks for KVM-compatible templates, allowing attackers who can register templates to deploy malicious instances on KVM-based environments. These malicious instances could then potentially access host filesystems, leading to compromised resource integrity, confidentiality breaches, data loss, denial of service, and the overall compromise of KVM-based infrastructure managed by CloudStack.
Key Insights
- Exploitation: The vulnerability is already being exploited "in the wild" by attackers. This signifies an urgent need for immediate action as malicious actors are actively leveraging this weakness.
- Impact: The vulnerability allows attackers to potentially gain full control of the host filesystems, compromising critical data, services, and the entire KVM-based infrastructure.
- Scope: The vulnerability affects all Apache CloudStack installations within the vulnerable version range, posing a significant risk to any organization utilizing these versions.
- SVRS: The vulnerability has an SVRS score of 56, which while not considered critical, is still a high score and underscores the severity of the potential impact.
Mitigation Strategies
- Upgrade: Immediately upgrade Apache CloudStack to versions 4.18.2.5, 4.19.1.3, or later, as these versions include the necessary patch addressing the vulnerability.
- Template Validation: Implement rigorous validation processes for all KVM-compatible templates registered by users. This includes ensuring they are flat files without any additional or unnecessary features.
- Regular Monitoring: Regularly monitor your Apache CloudStack environment for any suspicious activity and investigate any unusual events.
