CVE-2000-0984


TITLE

Cisco IOS software vulnerable to DoS via HTTP request containing "?/"

Trust: 0.8

sources: CERT/CC: VU#683677

DESCRIPTION

The HTTP server in Cisco IOS 12.0 through 12.1 allows local users to cause a denial of service (crash and reload) via a URL containing a "?/" string. A vulnerability exists in multiple versions of Cisco's Internetworking Operating System (IOS) software that allows an attacker to force affected switches and routers to crash and reboot. The device will enter an infinite loop when supplied with a URL containing a "?/" and an enable password. Subsequently, the router will crash in two minutes after the watchdog timer has expired and will then reload. In certain cases, the device will not reload and a restart would be required in order to regain normal functionality. This vulnerability is restricted to devices that do not have the enable password set or if the password is known or can be easily predicted. The vulnerable service is only on by default in the Cisco 1003, 1004 and 1005 routers. Users can identify vulnerable or invulnerable devices running IOS by logging onto the device and issuing the ?show version? command. If IOS is running on a vulnerable device the command will return ?Internetwork Operating System Software? or ?IOS (tm)? with a version number. Vulnerable IOS software may be found on the following Cisco devices: *Cisco routers in the AGS/MGS/CGS/AGS+, IGS, RSM, 800, ubr900, 1000, 1400, 1500, 1600, 1700, 2500, 2600, 3000, 3600, 3800, 4000, 4500, 4700, AS5200, AS5300, AS5800, 6400, 7000, 7200, ubr7200, 7500, and 12000 series. *Recent versions of LS1010 ATM switch. *Catalyst 6000 with IOS. *Catalyst 2900XL LAN switch with IOS. *Cisco DistributedDirector
