Hey all. I just installed snort/acid/mysql and its pretty cool. I keep getting a ridiculous amounts of reports about these UDP packets.
The summary in ACID says:
"MISC UPNP malformed advertisement".
Universal Plug and Play (UPnP) on Windows 98, 98E, 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.
Ummm...why would I have that? Here
is a link for a full explanation of the exploit. What could be causing this?
