TITLE

Microsoft IIS 4.0/5.0 Escape character vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-200004-027

DESCRIPTION

IIS 4.0 and 5.0 allows remote attackers to cause a denial of service by sending many URLs with a large number of escaped characters, aka the "Myriad Escaped Characters" Vulnerability. Requesting a malformed URL containing numerous escaped characters will cause Microsoft IIS performance to dramatically decrease until the URL has been processed
