ROSLYN.SECURITY.CA3061 : Do Not Add Schema By URL (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.SECURITY.CA3061 : Do Not Add Schema By URL (C#)

Summary

This overload of XmlSchemaCollection.Add method internally enables DTD processing on the XML reader instance used, and uses UrlResolver for resolving external XML entities. The outcome is information disclosure. Content from file system or network shares for the machine processing the XML can be exposed to attacker. In addition, an attacker can use this as a DoS vector.

This check corresponds to Roslyn rule CA3061. For full rule details, see the Microsoft website: CA3061.
