CVE-2001-0877 is a vulnerability of currently unknown severity. Universal Plug and Play (UPnP) on Windows 98, 98SE, ME, and XP allows remote attackers to cause a denial of service via (1) a spoofed SSDP advertisement that causes the client to connect to a service on another machine that generates a large amount of traffic (e.g., chargen), or (2) via a spoofed SSDP announcement to broadcast or multicast addresses, which could cause all UPnP clients to send traffic to a single target system.. EPSS estimates a 37.18% chance of exploitation in the next 30 days.
