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/1000/info // Misordered handshake sequences sent to a Windows Media Unicast Server via Windows Media Player will cause the server to crash. Restarting the Unicast Service, including any open sessions during the time of the crash, is required in order to regain normal functionality. This is due to the dependency of the application on successfully completing asychronous handshake requests in a proper sequential order between the client and the server. /* * * Jan-18-2000 * * [ http://www.rootshell.com/ ] * * Microsoft Media Server 4.1 - Denial of Service Attack * * This code will crash the Microsoft Media Unicast Server for * Windows NT.
