OVERVIEW

        Multiple vulnerabilities have been identified in 
         Oracle iLearning, version  6.2
        [1]


IMPACT

        The vendor has provided the following information regarding
        the vulnerability:
        
        "This Critical Patch Update contains 1 new security fix for
        Oracle iLearning.   This vulnerability is remotely
        exploitable without authentication,  i.e.,  may be exploited
        over a network without requiring user credentials." [1]
        
        
        
        "CVE-2018-2989
        
        8.2
        
        AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N
        
        The supported version that is affected is 6.2. Easily
        exploitable vulnerability allows unauthenticated attacker
        with network access via HTTP to compromise Oracle iLearning.
        Successful attacks require human interaction from a person
        other than the attacker and while the vulnerability is in
        Oracle iLearning, attacks may significantly impact
        additional products. Successful attacks of this
        vulnerability can result in  unauthorized access to critical
        data or complete access to all Oracle iLearning accessible
        data as well as  unauthorized update, insert or delete
        access to some of Oracle iLearning accessible data." [2]


MITIGATION

        Oracle states:
        
        "Due to the threat posed by a successful attack, Oracle
        strongly recommends that customers apply CPU fixes as soon
        as possible. Until you apply the CPU fixes, it may be
        possible to reduce the risk of successful attack by blocking
        network protocols required by an attack. For attacks that
        require certain privileges or access to certain packages,
        removing the privileges or the ability to access the
        packages from users that do not need the privileges may help
        reduce the risk of successful attack. Both approaches may
        break application functionality, so Oracle strongly
        recommends that customers test changes on non-production
        systems. Neither approach should be considered a long-term
        solution as neither corrects the underlying problem." [1]
