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.

source: https://www.securityfocus.com/bid/2175/info IBM HTTP Server contains AfpaCache directive which turns the Fast Response Cache Accelerator function on or off. WebSphere is a series of applications which are built upon IBM HTTP Server. Both IBM HTTP Server and Websphere are subject to a denial of service. This is caused by exhausting computer resources with malformed HTTP GET requests. A restart of the service is required inorder to gain normal functionality. GET / HTTP/1.0\r\nuser-agent: 20000xnull\r\n\r\n This request must be made multiple times before the system will freeze.
