Technical description

Interpretation conflict in ASP.NET in Microsoft .NET Framework 1.0, 1.1, and 2.0 for Windows 2000, XP, Server 2003, and Vista allows remote attackers to access configuration files and obtain sensitive information, and possibly bypass security mechanisms that try to constrain the final substring of a string, via %00 characters, related to use of %00 as a string terminator within POSIX functions but a data character within .NET strings, aka "Null Byte Termination Vulnerability."

Remediation

Check the references section for vendor advisories and patches from microsoft. Update windows_2000 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
