Version Disclosure (ASP.NET MVC)

Summary#

Invicti identified a version disclosure (ASP.NET MVC framework) in the target web server's HTTP response.

This information can help an attacker gain a greater understanding of the systems in use and potentially develop further attacks targeted at the specific version of ASP.NET MVC framework.

Impact#

An attacker might use the disclosed information to harvest specific security vulnerabilities for the version identified.

Remediation#

Configure your web server to prevent information leakage from the X-AspNetMvc-Version header of its HTTP response by adding the following code to the Application_Start() function in Global.asax.cs:

	MvcHandler.DisableMvcResponseHeader = true;
