Ensure compilation or scripting of database pages via the PageParserPaths elements is not allowed

AltaNível 1Automatizadasharepoint

Descrição

Allowing compilation or scripting of database pages via the "PageParserPaths" elements can lead to disclosure of compilation error messages containing server info and source code exposed to the user. Reads every local web application web.config (all zones) and prints the number of PageParserPath entries under SharePoint/SafeMode/PageParserPaths (expected 0). Run on each Web Front End; a missing web.config fails the audit. Run on a SharePoint farm server as a farm administrator; the audit loads the Microsoft.SharePoint.PowerShell snap-in and fails if it cannot.
