Overview<\/strong><\/p>\n

This report examines the vulnerability CVE-2025-10491, a significant security issue affecting MongoDB Server installations on Windows platforms. The vulnerability, if exploited, allows local attackers to inject malicious code into MongoDB’s process via DLL hijacking, potentially leading to system compromise or data leakage. This vulnerability is especially concerning for organizations relying on MongoDB Server versions v6.0, v7.0, and v8.0.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-10491
\nSeverity: High (CVSS: 7.8)
\nAttack Vector: Local
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

MongoDB Server | v6.0 to 6.0.24
\nMongoDB Server | v7.0 to 7.0.20
\nMongoDB Server | v8.0 to 8.0.4<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of the MongoDB Windows installation process, which may leave Access Control Lists (ACLs) unset on custom installation directories. An attacker with local access can exploit this oversight by introducing malicious DLL files into these directories. When the MongoDB Server process loads these hijacked DLLs, the malicious code is executed<\/a>, potentially leading to system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While the exact method will depend on the system’s specifics, a conceptual example of the DLL hijacking process could look like this:<\/p>\n

# gain local access and navigate to the custom installation directory\ncd C:\\path\\to\\mongodb\\installation\\directory\n# introduce the malicious DLL\ncp C:\\path\\to\\malicious.dll .\n# rename the malicious DLL to match a DLL that MongoDB Server is expected to load\nmv malicious.dll expected.dll<\/code><\/pre>\n
In this example, `expected.dll` would be the name of a legitimate DLL that the MongoDB Server process is expecting to load. When the MongoDB Server process tries to load the `expected.dll`, it loads the malicious DLL instead, executing the hostile code.<\/p>\n","protected":false},"excerpt":{"rendered":"
