EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

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.
