      Webcache Client Requests Bypass OHS mod_access Restrictions
    ------------------------------------------------------------------------

    SUMMARY

    A vulnerability in Oracle's Webcache allows attackers to access protected
    URLs by using webcache.

    DETAILS

    Vulnerable Systems:
     * Oracle Application Server version 10.x - OHS version 1.0.2

    Example:
    (Port 7778 = Webcache, Port 7779 = OHS)

    The following URLs are NOT protected if you access them via the Webcache
    server:
    http://server01:7778/dmsoc4j/AggreSpy?format=metrictable&nountype=ohs_child&orderby=Name
    http:// server01:7778/server-status
    http:// server01:7778/dms0

    The following URLs are protected if you access them via the OHS server:
    http://server01:7779/dmsoc4j/AggreSpy?format=metrictable&nountype=ohs_child&orderby=Name
    http:// server01:7779/server-status
    http:// server01:7779/dms0

    Workaround:
    Add "UseWebCacheIP ON" to Oracle's httpd.conf configuration file.

    Patch:
    Oracle addressed this issue by introducing the parameter "UseWebcacheIP"
    to the Oracle HTTP Server(OHS).
