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.

The tickets can be viewed on the website and in the admin panel. It is possible to inject arbitrary HTML and JS/VBS code into the title field of the ticket. If someone else views the ticket list, the code gets executed in the visitor's browser. This vulnerability is considered as critical since the tickets are also displayed in the administrator backend of Joomla. As soon as a user with extended priviledges views the ticket list in the backend, the code gets executed and damage can be caused. Example code for the ticket title field: "><IMG """><SCRIPT>alert("XSS")</SCRIPT> [:::::::::::::::::::::::::::::::::::::: 0x4 ::::::::::::::::::::::::::::::::::::::] >> Additional Information Advisory/Exploit Published = 12.11.2010 [:::::::::::::::::::::::::::::::::::::: 0x5 ::::::::::::::::::::::::::::::::::::::] >> Misc Greetz = cr4wl3r, JosS, packetstormsecurity.org, exploit-db.com [:::::::::::::::::::::::::::::::::::::: EOF ::::::::::::::::::::::::::::::::::::::]
