CVE-2025-12893— MongoDB Server 安全漏洞

Improper Certificate Validation May Allow Successful TLS Handshaking Despite Invalid Extended Key Usage Fields in MongoDB Server

Clients may successfully perform a TLS handshake with a MongoDB server despite presenting a client certificate not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = clientAuth may still be successfully authenticated via the TLS handshake as a client. This issue is specific to MongoDB servers running on Windows or Apple as the expected validation behavior functions correctly on Linux systems. Additionally, MongoDB servers may successfully establish egress TLS connections with servers that present server certificates not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = serverAuth may still be successfully authenticated via the TLS handshake as a server. This issue is specific to MongoDB servers running on Apple as the expected validation behavior functions correctly on both Linux and Windows systems. This vulnerability affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.16 and MongoDB Server v8.2 versions prior to 8.2.2

证书验证不恰当

MongoDB Server 安全漏洞

MongoDB Server是美国MongoDB公司的一套开源的NoSQL数据库。该数据库提供面向集合的存储、动态查询、数据复制及自动故障转移等功能。 MongoDB Server v7.0版本至7.0.26之前版本、v8.0版本至8.0.16之前版本和v8.2版本至8.2.2之前版本存在安全漏洞，该漏洞源于扩展密钥用法验证不当，可能导致TLS握手绕过。
