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

This report analyzes a critical vulnerability identified as CVE-2025-6709 in the MongoDB Server. The vulnerability exposes systems to a potential denial of service attack and potentially allows for system compromise or data leakage. It arises from improper handling of specific date values in JSON input when using OIDC authentication, affecting multiple versions of MongoDB Server. Understanding this vulnerability is crucial for system administrators and security professionals to ensure the safety of their MongoDB installations.<\/p>\n

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

CVE ID: CVE-2025-6709
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low for v7.0 and v8.0 versions, High for v6.0 versions
\nUser Interaction: None
\nImpact: Denial of Service leading to potential system compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

MongoDB Server | v7.0 prior to 7.0.17
\nMongoDB Server | v8.0 prior to 8.0.5
\nMongoDB Server | v6.0 prior to 6.0.21<\/p>\n

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

The vulnerability stems from the MongoDB Server’s mishandling of specific date values in JSON input when using OIDC authentication. An attacker can exploit this by sending a malicious JSON payload using the MongoDB shell, leading to an invariant failure and server crash, hence causing a denial of service.<\/p>\n

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

A conceptual exploit might involve sending a malicious JSON payload with a specific date value that triggers the server crash. The following is a pseudocode representation:<\/p>\n

mongo target.example.com\/db --eval 'db.collection.insert({date: new Date(\"malicious_date\")})'<\/code><\/pre>\n
In this pseudocode, `target.example.com\/db` represents the target MongoDB server, `db.collection.insert({date: new Date(“malicious_date”)})` is the malicious payload, with `”malicious_date”` being a date value that triggers the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
