      MagpieRSS Remote Command Execution
    ------------------------------------------------------------------------

    SUMMARY

    " <http://magpierss.sourceforge.net/> MagpieRSS provides an XML-based
    (expat) RSS parser in PHP."

    MagpieRSS does not properly validate user provided input allowing
    attackers to cause the program to execute arbitrary code.

    DETAILS

    Vulnerable Systems:
     * MagpieRSS version 0.71.1 and prior

    Immune Systems:
     * MagpieRSS version 0.72

    A vulnerability has been identified in MagpieRSS that could be exploited
    by remote attackers to execute arbitrary commands. This flaw is due to an
    input validation error in the "_httpsrequest" function of Snoopy when
    passing malformed URLs to the "exec()" call, which could be exploited by
    remote attackers to execute arbitrary commands via a specially crafted
    URL.
