Cisco uBR10012 series devices automatically enable SNMP read/write access
Since there are no access restrictions on this community string , attackers can exploit this to gain complete control of the device
By sending an SNMP set request with a spoofed source IP address the attacker will be able to get the Victim router to send him its configuration file.
With this information, the remote computer will be able to have complete control over this router
Fixes- Software updates available on the CICSO site that will fix the Read/Write problem
