      EMC Navisphere Manager Directory Traversal
    ------------------------------------------------------------------------

    SUMMARY

    " <http://www.emc.com/products/storage_management/navisphere.jsp> EMC
    Navisphere storage management software is a suite of tools that enables
    discovery, monitoring, provisioning, and reporting on EMC CLARiiON FC4700
    Storage Systems."

    EMC Navisphere Manager does not properly filter incoming requests and as
    such is vulnerable to a directory traversal vulnerability.

    DETAILS

    Vulnerable Systems:
     * Navisphere Manager Base version 6.4.1.0.0

    Immune Systems:
     * Management Server version 6.6.0.5.0
     * Management Server Base version 6.6.0.5.0
     * Windows Management Server version 6.6.0.5.0
     * Management Server version 6.5.4.0.0
     * Management Server Base version 6.5.4.0.0
     * Windows Management Server version 6.5.4.0.0
     * Management Server version 6.4.8.0.0
     * Management Server Base version 6.4.8.0.0
     * Windows Management Server version 6.4.8.0.0

    Exploitation of a directory traversal vulnerability in EMC Navisphere
    Manager could allow an attacker to retrieve arbitrary files from the
    system running Navisphere Manager as well as retrieve directory listings.

    The following request can be used to retrieve the Navisphere Manager log
    file, which often contains the administrative password in plain-text:
    http://vulnerable/../../../../../../../EMC/NAVISPHERE/common/log/navimon.log

    Another flaw allows a user to list the contents of arbitrary directories
    by simply appending a '.' to the end of a request.

    Workaround:
    Limit access to the Navisphere Manager server to only trusted hosts by
    limiting access to trusted users only on TCP port 80.

    Vendor Status:
    "The vulnerability identified is found in older versions of Navisphere
    Management Server (r), for which an update has been issued. In these
    updated versions, HTTP validation is implemented. Attempts to traverse
    the file system by way of a URL (e.g., "../../..") are detected and such
    requests are rejected with the following error:

    'The page cannot be displayed'
