      PowerLink WAN Aggregator Multiple Vulnerabilities
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.astrocorp.com/> PowerLink WAN Aggregator is an Intelligent
    Link Load Balancing with Automatic WAN Fail-Over for 100% Always Available
    Internet Connectivity. An interesting way to increase Broadband bandwidth
    among several connections. Multiple vulnerabilities have been found in the
    product allowing attackers to gain elevated privileges, and access files
    that reside outside the bound HTML root directory.

    DETAILS

    Vulnerable systems:
     * PowerLink WAN Aggregator version 1.7.3.1
     * Boa web server version 0.92r

    The below vulnerabilities occur because the product is based upon the Boa
    web server, which as we reported
    <http://www.securiteam.com/unixfocus/6G0081P0AI.html> previously is
    vulnerable to attack.
