Security Bulletin: Potential Security Exposure in IBM Lotus Sametime Configuration Servlet (CVE-2011-1370)

Flash (Alert)


Sametime configuration servlet may allow third party access to configuration data unless authentication is enabled.



    Sametime configuration servlet may allow third party access to configuration data unless authentication is enabled.

    CVE ID: CVE-2011-1370:

    DESCRIPTION: The Sametime server contains a configuration servlet that is accessed by several Sametime server processes. By default, this servlet does not require authentication, which could potentially allow an unauthorized user to obtain read access to configuration data. Administrators are advised to protect this servlet by configuring Sametime to require authentication to this servlet.

    CVSS Base Score: 5.0
    CVSS Temporal Score: See for the current score
    CVSS Environmental Score*: Undefined
    CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

    All Sametime Platforms

    It is recommended that all Sametime installations immediately secure this servlet by following the instructions below.
    Administrators should also take steps to update the passwords on all credentials that are stored within the Sametime configuration database.

    Sametime Development currently plans to establish authentication as the default setting of this servlet in a future release.

The steps to secure these servlets are as follows:

    Known issues or limitations once authentication is enabled

    When upgrading community servers, you might get a warning that registration of the upgrade failed.
    Manual registration of Sametime Community Servers and Clusters with the Sametime System Console might not work.


SSL can be enabled to further protect the data when it is actively being accessed by administration functions. If your Sametime Community Servers are accessible from the Internet, then this step is highly recommended.
