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.

<b>Description:
This ocx contains a lot of extreme dangerous methods. Theese two are very interesting, they are:
"StartProcess()" and "SyncShell()"
Using one of them, you'll be able to run every program you like, simply giving to the method the
right argument.
In this PoC, I use the "StartProcess()" method to execute the calc.exe, but you can do everything
you like.
Anyway, I think you could imagine what impact could have this kind of vulnerability :D
Other dangerous methods of this ocx are:
"SaveAs()"
"CABDefaultURL()"
"CABFileName()"
"CABRunFile()"</b>
