APPLIES TO
- Microsoft Internet Information Server 4.0
- Microsoft Site Server 3.0 Standard Edition

- Microsoft Windows NT 4.0 Service Pack 3
- Microsoft Windows NT 4.0 Service Pack 4

This article was previously published under Q246401
SYMPTOMS
RFC 1738 specifies that Web Servers should allow hexadecimal digits to be input in URLs by preceding them with the so-called "escape" character, a percent sign.
Microsoft Internet Information Server (IIS) complies with the RFC 1738 specification, but also accepts characters after the percent sign that are not hexadecimal digits. Some of these translate to printable ASCII characters, and this could provide an alternate means of specifying files in URLs.
It is possible when using the Internet Database Connector (IDC) to create links, or you are using the return value arguments passed to other documents. When this happens you may be unable to pass arguments that contain spaces.
IIS 4.0 may improperly translate non-hexadecimal characters preceded by a percent sign. For example %3p is translated into an \\\"I\\\".
The vulnerability does not affect IIS; even specifying a file name through this alternate method does not bypass IIS access controls. However, third-party software that runs atop IIS but does not perform canonicalization, is affected by it.
RESOLUTION
Windows NT 4.0
