source: http://www.securityfocus.com/bid/1177/info All R-series platforms with firmware between 4.3.8 and 4.6.2 (inclusive) allow users who already have access to the router to modify SNMP tables which they should not be able to access. The router has a command-line mode that is reached by typing control-N after the user has passed the intial login test. At the "#" prompt one can then do most management of the device. This includes the setting of SNMP community strings in spite of the limitation imposed by the administrator. The following devices are confirmed as vulnerable: R2020 Dual Analog Router R3100 ISDN Router R3100-I ISDL Router R3100-T IDSL router for Covad R3232-I IDSL 4-IMUX router R5100 Serial router R5200 DDS router R5220 DDS router w/ V.90 backup R5300 T1 router R5320 T1 router w/ V.90 backup R5331 T1 router w/ ISDN backup R7100-C SDSL router R7120 SDSL Router w/int V.90 R7131 SDSL router w/int ISDN R7171 SDSL 2x IMUX router R7200-T SDSL router for Covad R7220 SDSL router w/int.V.90 R7231 SDSL router w/int ISDN R9100 Ethernet-to-ethernet Router # set snmp community RO wookie or # set snmp community RW wookie The exploit can only be attempted by those with existing access login to the device.
