EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

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.

OpenVPN Private Tunnel Core Service Unquoted Service Path Elevation Of Privilege Vendor: OpenVPN Technologies, Inc Product web page: http://www.openvpn.net Affected version: 2.1.28.0 (PrivateTunnel 2.3.8) Summary: Private Tunnel is a new approach to true Internet security creating a Virtual Private Tunnel (VPT) or Virtual Private Network (VPN) that encrypts, privatizes, and protects your Internet traffic. Desc: Private Tunnel application suffers from an unquoted search path issue impacting the Core Service 'ptservice' service for Windows deployed as part of PrivateTunnel bundle. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could potentially be executed during application startup or reboot. If successful, the local user's code would execute with the elevated privileges of the application.
