p2p news / p2pnet - 09/20/05

“Security researchers say they have found weaknesses in Cisco's Internet Operating System (IOS) which may enable an Internet worm to spread between Cisco routers,” says Netcraft. “But Arhont Ltd. denied reports that such a worm had actually been developed.”

The Bugtraq mailing list has a post from Arhont's Andrei Mikhailovsky which apparently reveals “weaknesses in the way IOS uses the Enhanced Interior Gateway Routing Protocol (EIGRP), which handles information exchange between routers,” says the story.

Vulnerability?.. only for sloppy configuration

If EIGRP vulnerabilities in the enterprise are a serious threat, then IT managers had best get their butts in gear. Otherwise, public connections should be properly controlled via ACL, hence this isn't really an issue for 99.9% of the IOS routers out there.
