    EMC Navisphere Manager Directory Traversal Vulnerability

    iDEFENSE Security Advisory 08.05.05
    www.idefense.com/application/poi/display?id=288&type=vulnerabilities
    August 05, 2005

    I. BACKGROUND

    EMC Navisphere storage management software is a suite of tools that
    enables discovery, monitoring, provisioning, and reporting on EMC
    CLARiiON FC4700 Storage Systems.

    II. DESCRIPTION

    Remote exploitation a directory traversal vulnerability in EMC Corp.
    Navisphere Manager could allow an attacker to retrieve arbitrary files
    from the system running Navisphere Manager as well as retrieve directory

    listings.

    The vulnerability specifically exists due to a lack of validation of
    HTTP requests. The following request can be used to retrieve the
    Navisphere Manager log file, which often contains the administrative
    password in plaintext:

    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. The following request

    will list the contents of the server root:

    http://vulnerable/.

    III. ANALYSIS

    Successful exploitation allows remote attackers to gain access to files
    on the target system; in some cases, it is possible to retrieve the
    Clarion Administrator password by viewing log files.

    IV. DETECTION

    Navisphere Manager Base 6.4.1.0.0 is reportedly vulnerable.

    V. WORKAROUND

    Limit access to the Navisphere Manager server to only trusted hosts.
    Since the Manager runs on TCP port 80, apply filters where possible.

    VI. VENDOR RESPONSE

    "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'

    Customers running Navisphere Manager Version 6.4, 6.5, or 6.6 who do not
    have the following revisions (or higher) should contact their authorized
    EMC Service representative:

    6.6.0.5.0 Management Server
    6.6.0.5.0 Management Server Base
    6.6.0.5.0 Windows Management Server

    6.5.4.0.0 Management Server
    6.5.4.0.0 Management Server Base
    6.5.4.0.0 Windows Management Server

    6.4.8.0.0 Management Server
    6.4.8.0.0 Management Server Base
    6.4.8.0.0 Windows Management Server

    Later revisions of Navisphere Management Server that come bundled with
    the FLARE Operating Environment (FOE) already contain this fix, starting
    with FLARE 14 (rev 02.07) released in June 2004."

    VII. CVE INFORMATION

    The Common Vulnerabilities and Exposures (CVE) project has assigned the
    name CAN-2005-2357 to the "../" issue and CAN-2005-2358 to the trailing
    dot issue. These are candidates for inclusion in the CVE list
    (http://cve.mitre.org), which standardizes names for security problems.
