AI-suggested
Organizations should immediately upgrade affected MongoDB Server versions to 6.0.25, 7.0.21, or 8.0.5 or later, where the issue is fixed. Until patching is possible, administrators must verify and enforce strict ACLs on all MongoDB installation directories, especially custom paths, to prevent unauthorized write access. Use Windows security tools to audit directory permissions and remove write privileges from non-administrative users. Additionally, restrict local access to MongoDB servers to trusted personnel only, minimizing the risk of local attacker presence. Employ application whitelisting and endpoint protection solutions to detect and block unauthorized DLL loading. Regularly monitor MongoDB logs and system event logs for suspicious activity indicative of DLL hijacking attempts. Finally, review and harden overall Windows host security posture to reduce the likelihood of local privilege escalation and lateral movement.
Description
The MongoDB Windows installation MSI may leave ACLs unset on custom installation directories allowing a local attacker to introduce executable code to MongoDB's process via DLL hijacking. This issue affects MongoDB Server v6.0 version prior to 6.0.25, MongoDB Server v7.0 version prior to 7.0.21 and MongoDB Server v8.0 version prior to 8.0.5
