Detailsinfo

A vulnerability, which was classified as critical, was found in Microsoft IIS 4.0/5.0 (Web Server). Affected is an unknown code block in the library shtml.dll of the component Error Message Handler. The manipulation with an unknown input leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Vulnerabilities in IIS 4.0 and 5.0 do not properly protect against cross-site scripting (CSS) attacks. They allow a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site, aka the "IIS Cross-Site Scripting" vulnerabilities.
