TITLE
Multiple Vendor SNMP World Writeable Community Vulnerability
Trust: 0.3
DESCRIPTION
In a number of network devices/operating systems, some default communites are world-writeable and therefore allow remote users to configure properties of the device/OS without any authorization (other than knowledge of the community name). Some of the common default communities/vendors are: public (ascend,cisco,bay networks (nortel),microsoft,sun,3com, aix) private (cisco,bay networks (nortel),microsoft,3com, brocade, aix, netapp) write (ascend, very common) "all private" (sun) monitor (3com) manager (3com) security (3com) OrigEquipMfr (brocade) "Secret C0de" (brocade) admin default password tivoli openview community snmp snmpd system (aix, others) the name of the router (ie, 'gate') The attacks can include manipulating routing tables and corrupting ARP caches, which can lead to further compromise. This type of vulnerability has been seen for quite some time; more information on it is listed in the credit section. NOTE: There may be more products shipping with default read/writeable communities. If you have any more information on what may be vulnerable (more specific firmware versions or corrections), email <vuldb@securityfocus.com>.
