      Multiple Vulnerabilities in SLWebMail
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.slmail.com> SLWebMail is a web based e-mail system that runs
    on top of Microsoft's Internet Information Server. It is vulnerable to
    many different kinds of issues, such as buffer overflows, arbitrary file
    access, and physical path revelation.

    DETAILS

    Vulnerable systems:
     * SLWebMail version 3

    Buffer Overflows
    Many of the ISAPI DLL applications that form SLWebMail are vulnerable to
    buffer overflow vulnerabilities. By passing overly long value parameters
    in the query string, the overflows can be triggered.

    Module: showlogin.dll
    Parameter: Language

    Module: recman.dll
    Parameter: CompanyID

    Module: admin.dll
    Parameter: CompanyID

    Module: globallogin.dll
    Parameter: CompanyID

    Arbitrary File Access
    ShowGodLog.dll can be accessed without requiring a remote user to
    authenticate. This ISAPI application is used to show SLWebMail's log file.
    However, by providing the path, relative or full, to any file that the
    anonymous Internet account has read access to then access to the contents
    can be gained, even outside of the web root.

    Physical Path Revelation
    By making invalid requests to certain DLLs such as WebMailReq.dll the
    complete physical path to the DLL is revealed. This information can be
    used to help with other attacks.

    Fix Information
    NGSSoftware alerted SLMail to these issues in February and an update has
    been released. See <http://www.slmail.com> http://www.slmail.com for more
    details.
