TITLE

Cisco IOS of SGBP Service disruption in (DoS) Vulnerabilities

DESCRIPTION

Unspecified vulnerability in Stack Group Bidding Protocol (SGBP) support in Cisco IOS 12.0 through 12.4 running on various Cisco products, when SGBP is enabled, allows remote attackers on the local network to cause a denial of service (device hang and network traffic loss) via a crafted UDP packet to port 9900. Cisco IOS SGBP is prone to a remote denial of service vulnerability. This issue arises on devices that have been configured to run SGBP. A successful attack causes a device to hang and fail to respond to further requests. It should be noted that a system watchdog timer will detect this condition after a delay and restart the device. Internet Operating System (IOS) is an operating system used on CISCO routers. Remote attackers can use this loophole to launch denial-of-service attacks on the device. A specially crafted UPD message can cause a denial of service in the Cisco IOS-provided SGBP implementation. Sending the above message to port 9900 of an affected device can cause it to freeze and stop responding or transmitting traffic. The vulnerability is caused due to an error in the handling of the SGBP protocol (Stack Group Bidding Protocol). This can be exploited to cause a vulnerable device to become unresponsive and trigger a hardware reset by sending a specially crafted UDP datagram to port 9900. SOLUTION: Fixes are available for IOS 12.0, 12.1, 12.2, 12.3, and 12.4 (see patch matrix in vendor advisory). http://www.cisco.com/warp/public/707/cisco-sa-20060118-sgbp.shtml#software PROVIDED AND/OR DISCOVERED BY: Reported by vendor.
