| description | Cisco Internetwork Operating System (IOS) Software release trains 12.0S, 12.1E, 12.2, 12.2S, 12.3, 12.3B and 12.3T may contain a vulnerability in processing SNMP requests which, if exploited, could cause the device to reload. The vulnerability is only present in certain IOS releases on Cisco routers and switches. This behavior was introduced via a code change and is resolved with CSCed68575. This vulnerability can be remotely triggered. A successful exploitation of this vulnerability may cause a reload of the device and could be exploited repeatedly to produce a denial of service (DoS). |
