Article contents: Vulnerability Description
ePO is vulnerable to the Java CVEs mentioned above.

This ePO update resolves the following issues:
 
CVE-2018-2783
Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized creation, deletion, or modification access to critical data or all Java SE accessible data as well as unauthorized access to critical data or complete access to all Java SE accessible data.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2783  

CVE-2018-2794
Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Java SE executes to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2794 

CVE-2018-2795
Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2795 

CVE-2018-2796
Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2796   

CVE-2018-2797
Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2797  

CVE-2018-2799
Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE.
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-2799  

CVE-2018-2815

How do I know if my McAfee product is vulnerable or not?
For ePO:
Check the version and build of ePO that is installed. For information on how to check the version, see KB52634.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: http://www.first.org/cvss/.
 
When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.
