CVE-2024-8207 is a vulnerability classified under CWE-114 (Process Control) affecting MongoDB Server versions 5.0 prior to 5.0.14 and 6.0 prior to 6.0.3, specifically on Linux operating systems. The vulnerability arises from the possibility that, under certain highly specific configurations of the host system and MongoDB server binary installation, an actor with existing host-level access can manipulate the environment such that the MongoDB server binary loads shared libraries controlled by the attacker when the server starts. This can lead to the attacker gaining full control over the MongoDB server process. The vulnerability requires the attacker to already have high-level privileges on the host (e.g., root or equivalent) and does not require user interaction. The CVSS v3.1 score is 6.4 (medium severity), reflecting the need for high privileges and complex conditions for exploitation but the high impact on confidentiality, integrity, and availability if exploited. The vulnerability is not known to be exploited in the wild as of the publication date. The root cause is related to unsafe process control and dynamic library loading mechanisms, which can be influenced by an attacker with host-level access to insert malicious shared libraries that the MongoDB server loads at startup. This can result in arbitrary code execution within the MongoDB server process context, potentially compromising the database and any data it manages. The vulnerability is limited to Linux environments and does not affect other operating systems. MongoDB has released fixed versions 5.0.14 and 6.0.3 to address this issue.

For European organizations, this vulnerability poses a significant risk primarily in environments where MongoDB is deployed on Linux servers and where host-level access controls may be insufficient or compromised. If exploited, an attacker could gain full control over the MongoDB server process, leading to unauthorized data access, data manipulation, or service disruption. This could result in breaches of sensitive personal data protected under GDPR, causing legal and financial repercussions. Additionally, the integrity and availability of critical applications relying on MongoDB could be severely impacted, affecting business continuity. Since exploitation requires prior host-level access, the vulnerability is often a secondary attack vector following initial system compromise. However, in multi-tenant or cloud environments common in Europe, where Linux-based MongoDB instances are widespread, the risk of lateral movement and privilege escalation increases. Organizations in sectors such as finance, healthcare, and government, which heavily rely on MongoDB for critical data storage, are particularly vulnerable to the consequences of this exploit.

1. Upgrade MongoDB Server to version 5.0.14 or 6.0.3 or later immediately to apply the official patches addressing this vulnerability. 2. Harden host-level security by enforcing strict access controls and minimizing the number of users with root or equivalent privileges on Linux hosts running MongoDB. 3. Implement mandatory access controls (e.g., SELinux, AppArmor) to restrict the MongoDB process from loading unauthorized shared libraries or executing untrusted code. 4. Regularly audit and monitor the integrity of shared libraries and MongoDB binaries to detect unauthorized modifications. 5. Use containerization or sandboxing techniques to isolate MongoDB processes and limit the impact of potential host-level compromises. 6. Employ file system permissions and mount options to prevent unauthorized write access to directories containing shared libraries and MongoDB binaries. 7. Monitor system logs and MongoDB logs for unusual startup behaviors or library loading activities that could indicate exploitation attempts. 8. Conduct regular vulnerability assessments and penetration tests focusing on host-level security and privilege escalation paths to identify and remediate weaknesses before exploitation.
