OVERVIEW

        Multiple security vulnerabilities have been identified in McAfee 
        Intrushield NSM.


IMPACT

        The vendor has provided the following information regarding these
        vulnerabilities:
        
        "Intrushield NSM update fixes XSS flaw
        
        This update fixes an XSS (cross-site scripting) bug found in the 
        Intrushield / Network Security Platform management console.
        
        The XSS bug would allow an attacker to send a malicious link to a 
        Network Security Manager (NSM) administrator. If the administrator 
        were to click the link, the attacker could execute javascript in 
        the browser context of the NSM administrator. The attacker would 
        then have the ability to steal cookies or perform other actions. 
        McAfee has closed the XSS hole in NSM update 5.1.11.6 and verified 
        that the Network Security Manager is no longer vulnerable to this 
        attack." [1]
        
        "Intrushield NSM update fixes Session Hijacking flaw
        
        This update fixes a "Session Hijacking" bug found in the 
        Intrushield / Network Security Platform management console.
        
        The "Session Hijacking" bug would allow an attacker to steal 
        the cookie used for authentication to the website you are 
        currently viewing. This is due to the lack of the httponly 
        mechanism tag in the cookie generated by the Network Security 
        Manager (NSM). McAfee has resolve this issue in NSM update 
        5.1.11.8.1 and verified that the Network Security Manager is 
        no longer vulnerable to this attack." [2]
        
        These vulnerabilities affect IntruShield NSM 5.1.7.7 [1,2]


MITIGATION

        To patch both of these vulnerabilities, upgrade NSM software 
        to NSM 5.1.11.8.1 or above.
