Version Disclosure (ASP.NET MVC)
Severity: Low
Summary #
Netsparker 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;
