EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres 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 ::::::::::::::::::::::::::::::::::::::]
