Dark_Matter Posted March 13, 2006 CID Share Posted March 13, 2006 Can't remember what website i got this from off hand, but found this one intresting. ('binary' encoding is not supported, stored as-is) It appears that various routers are prone to an IRC-only DoS attack. Particularly Netgear and Linksys routers have been shown vulnerable. If a client behind one of the vulnerable routers connects to an IRC server on port 6667 (and only 6667, does not DoS with other ports) and a user posts the following string in either a channel, private message, ctcp, notice, etc.. the router will drop the connection. The string is as follows: DCC SEND anylongrandomstringhere It is most commonly being seen as DCC SEND "string" 0 0 0 but that appears to be unneccessary. The string does need to be 15+ chars in length. Further, it appears the routers that are vulnerable to this are running vxworks as their embedded OS. Older linux Linksys routers appear to be immune.
