AI-Generated

The MongoDB C# Driver is vulnerable due to improper handling of delimiters in connection-URL construction, allowing low-privileged users to inject malicious connection options. This can lead to unauthorized modification of security-relevant settings, potentially compromising the integrity and security of the database connection. Organizations using the MongoDB C# Driver should prioritize addressing this vulnerability to mitigate risks associated with unauthorized access and configuration changes.

Original NVD Description

Improper neutralization of delimiters in connection-URL construction allows connection-option injection in the MongoDB C# Driver. When an application passes untrusted text into the driver's connection-URL builder and round-trips the builder back into a client configuration, the untrusted text is serialized without neutralizing the URL/option delimiters and is then re-parsed as authoritative connection options. A low-privileged user of such an application can thereby introduce or suppress security-relevant connection settings.
