Summary

Cisco IOS 12.2 and 12.3 on Cisco uBR10012 series devices, when linecard redundancy is configured, enables a read/write SNMP service with "private" as the community, which allows remote attackers to obtain administrative access by guessing this community and sending SNMP requests.

descriptionCisco uBR10012 series devices automatically enable Simple Network Management Protocol (SNMP) read/write access to the device if configured for linecard redundancy. This can be exploited by an attacker to gain complete control of the device. Only Cisco uBR10012 series devices that are configured for linecard redundancy are affected. Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available.

descriptionBUGTRAQ ID: 31355 CVE ID: CVE-2008-3807 CNCVE ID:CNCVE-20083807 Cisco uBR10012是一款通用宽带路由器。 Cisco uBR10012路由器存在默认SNMP公共串,远程攻击者可以利用漏洞完全控制此类型设备。 当配置线路卡冗余时Cisco uBR10012系列设备需要与RF交换机通信,这个通信基于SNMP,当线路卡冗余在Cisco uBR10012系列设备上启用时,SNMP也自动启用默认的私有公共串来提供读写权力,由于对这个公共串没有任何访问限制,可导致攻击者完全控制设备。 此Cisco Bug ID为CSCek57932,CVE ID为CVE-2008-3807。 Cisco uBR 10012 可参考如下安全公告获得补丁信息: <a href=http://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml target=_blank>http://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml</a>
