• Important: ASP.NET Security Vulnerability

  Andrew Conrad - MSFTMicrosoft EmployeeMonday, September 20, 2010 10:55 PM

  Over the weekend the ASP.NET team released a Microsoft Security Advisory about a security vulnerability found in ASP.NET:

   

  http://www.microsoft.com/technet/security/advisory/2416728.mspx
  
  

  The WCF Data Services team looked into the issue and don’t believe there is any additional exposure to the vulnerability beyond what is exposed by ASP.NET.   However, if the WCF Data Service is hosted in ASP.NET, it is quite possible that the vulnerability is present.  If any users use the ASP.Net encryption logic to hide sensitive information from the client and use that encrypted data to make decisions in the WCF Data Service, they can run into this issue. Below are few examples:

   

  ·         If you use an encrypted cookie to make decisions to which database to connect in CreateDataSource method

  ·         If you use an encrypted cookie to figure out whether the user is an admin rather than using RoleManager in the server

  ·         If you use an encrypted cookie to apply business logic in change/query interceptors

   

  For a complete description of the vulnerability, please read Scottgu’s post on the subject:

• WCF Data Services Voting Site Now Available!

  The WCF Data Services team is beginning to explore improvements and new features for our next release.  As part of this process, it’s critical that we hear your feedback, as it helps us ensure that what we build actually meets your requirements in real-world scenarios.  To enable this we’ve launched a new site that will allow you to interact more directly with the development team and provide input: http://dataservices.mswish.net .

  The site’s pretty simple and self-explanatory – you can add a new feature request or vote for feature requests that are already there. We hope you’ll try it out and vote on the features you most want to see added.  Finally, as features move from ideas into actual development we’ll post our thoughts and ideas to the team blog at http://blogs.msdn.com/astoriateam
