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.

Description:
Cross-Site Request Forgery vulnerability in the e107_admin/download.php page, which is also vulnerable to SQL injection in the POST form.
The e-token or ac tokens are not used in this page, which results in the CSRF vulnerability. This in itself is not a major security vulnerability but when done in conjunction with a SQL injection attack it can result in complete information disclosure.
The parameters which are vulnerable to SQL injection on this page include: download_url, download_url_extended, download_author_email, download_author_website, download_image, download_thumb, download_visible, download_class.
The following is an exploit containing javascript code that submits a
POST request on behalf of the administrator once the page is visited. It contains a SQL injection that would provide the username and password (in MD5) of the administrator to be added to the Author Name of a publicly available download.
