CVE-2008-2930 : Detail

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.

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.

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
