Remarks
The SchemeSettingElementCollection class represents the <schemeSettings> element under the Uri section within a configuration file.
The SchemeSettingElementCollection class and the <schemeSettings> section in a configuration file looks generic, implying that an application can specify any System.GenericUriParserOptions enumeration value for any scheme. In fact, only the GenericUriParserOptions.DontUnescapePathDotsAndSlashes flag for HTTP and HTTPS schemes are supported. All other settings are ignored.
By default, the System.Uri class un-escapes percent encoded path delimiters before executing path compression. This was implemented as a security mechanism against attacks like the following:
http://www.contoso.com/..%2F..%2F/Windows/System32/cmd.exe?/c+dir+c:\
If this URI gets passed down to modules not handling percent encoded characters correctly, it could result in the following command being executed by the server:
c:\Windows\System32\cmd.exe /c dir c:\
For this reason, System.Uri class first un-escapes path delimiters and then applies path compression. The result of passing the malicious URL above to System.Uri class constructor results in the following URI:
http://www.microsoft.com/Windows/System32/cmd.exe?/c+dir+c:\
This default behavior can be modified to not un-escape percent encoded path delimiters using the SchemeSettingElement class.
