.NET Framework - Cross-Site Scripting via ValidateRequest Bypass

Title source: llm
STIX 2.1

Description

Request Validation (aka the ValidateRequest filters) in ASP.NET in Microsoft .NET Framework without the MS07-040 update does not properly detect dangerous client input, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a query string containing a "</" (less-than slash) sequence.
