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.

EDB Verified : Yes

source: https://www.securityfocus.com/bid/30871/info Red Hat Directory Server is prone to a denial-of-service vulnerability because the server fails to handle specially crafted search patterns. An attacker can exploit this issue to consume CPU resources with one search request, effectively blocking additional search requests from executing. Legitimate users may be prevented from authenticating to network resources that use the affected server for authentication. Red Hat Directory Server 7.1 and 8 are affected. The following example regular expressions are available: 2.6/AV:N/AC:H/Au:N/C:N/I:N/A:P 4.0/AV:N/AC:L/Au:S/C:N/I:N/A:P
