IOS glitch could leave VoIP-enabled routers vulnerable to DoS attacks

By Phil Hochmuth
Network World Fusion, 01/21/05

Cisco warned this week that an IOS software glitch could leave 
VoIP-enabled routers vulnerable to attack. 

The software flaw affects only Cisco routers running IOS Telephony 
Services, CallManager Express or Survivable Remote Site Telephony 
(SRST). These services use Cisco's Skinny Call Control Protocol 
(SCCP, or Skinny), which controls signaling between Cisco IP 
telephones and CallManager call processors. The IOS bug could 
allow an attacker to send malformed packets to the Skinny port 
on a Cisco VoIP-enabled router, Cisco says. 

"Successful exploitation of the vulnerability may result in a 
device reload," according to a Cisco Web advisory. "Repeated 
exploitation could result in a Denial of Service (DoS) attack."
