VAR-200106-0024
Vulnerability from variot - Updated: 2025-04-03 22:30IIS 5.0 and Microsoft Exchange 2000 allow remote attackers to cause a denial of service (memory allocation error) by repeatedly sending a series of specially formatted URL's. A vulnerability that affects Microsoft IIS 5.0 and Exchange 2000 allows an intruder to disrupt IIS web services and web-based mail services served via an Exchange server. Microsoft Exchange is subject to a denial of service condition due to the handling of web client requests. If an authenticated user requests a specially crafted URL multiple times to the host running Exchange, the web based mail service could stop responding. A restart of the service is required in order to gain normal functionality. Update: Microsoft IIS 5.0 suffers from a similar issue
