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.

Vulnerability title: Remote Code Execution in ownCloud CVE: CVE-2014-2044 Vendor: ownCloud Product: ownCloud Affected version: 4.0.x & 4.5.x Fixed version: 5.0 Reported by: Alejo Murillo Moya Details: A remote code execution has been found and confirmed within ownCloud as an authenticated user. A successful attack could allow an authenticated attacker to execute PHP code, which could lead to a full compromise of the server and associated infrastructure. Please note that only the Windows versions of ownCloud are affected and that valid credentials are required. It is possible to create a custom .htaccess into the user's folder on Windows version of the application, which will enable PHP execution on the folder.
