      Default SNMP Community in Surecom Broadband Router
    ------------------------------------------------------------------------

    SUMMARY

    The default router Surecom Broadband installation enables SNMP (Simple
    Network Management Protocol) server with default community names for read
    and read/write access. This would allow a remote attacker to completely
    compromise the remote router.

    DETAILS

    Vulnerable systems:
     * Surecom Broadband Router EP-4501

    Both the community name public (Which allows read access to the mentioned
    device, providing enumeration and gathering of sensitive network
    information) and the community name secret (Which allows read/write access
    to device, thus allowing restart and change of the network settings of the
    broadband router) are present in the default installation of the router.
    The SNMP server is enabled by default from the LAN and WAN interfaces.

    Impact:
    This vulnerability allows LAN and internet malicious attackers to retrieve
    and change network settings of the router.

    Possible Solutions:
    Disable default SNMP implementation, or change default community names.

    Vendor response:
    According to the Arhont Ltd. policy, all of the found vulnerabilities and
    security issues will be reported to the manufacturer 7 days before
    releasing them to the public domains.
