OVERVIEW:

        Avaya has released two (2) security bulletins correcting multiple
        vulnerabilities in multiple products.


IMPACT:

        The vendor has described these vulnerabilities as:

        "The Web management interface on several versions of Avaya SIP
        Enablement Services (SES) was found to contain input validation
        vulnerabilities. This could potentially allow for a user of the Web
        management interface to execute arbitrary code." [1]

        "The Web management interface on several versions of Avaya SIP
        Enablement Services (SES) was found to allow unauthorized access to
        several files. This could allow a remote user to view these files
        without being authenticated to the Web management interface." [1]

        "The Web management interface on several versions of Avaya
        Communication Manager was found to contain input validation
        vulnerabilities. This could potentially allow for an authenticated
        user of the Web management interface to execute arbitrary code." [2]


MITIGATION:

        Customers using Avaya SIP Enablement Services 3.x and 4.0 should
        upgrade to SES 5.0 or later. [1]

        Customers using Avaya Communication Manager (CM) 3.1.x should upgrade
        to CM 3.1.4 SP2 or later. [2]
        Customers using Avaya Communication Manager (CM) 4.0.x should upgrade
        to 4.0.3 SP1 or later. [2]
