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/2052/info FTP Serv-U is an internet FTP server from CatSoft. Authenticated users can gain access to the ftproot of the drive where Serv-U FTP has been installed. Users that have read, write, execute and list access in the home directory will have the same permissions to any file which resides on the same partition as the ftproot, once a user is in the home directory they can successfully transfer any files using specially crafted GET requests. All hidden files will be revealed even if the 'Hide hidden files' feature is on. Successful exploitation of this vulnerability could enable a remote user to gain access to systems files, password files, etc. This could lead to a complete compromise of the host. ftp> cd \..%20. 250 Directory changed to /.. ftp> cd %20..%20%20../winnt 250 Directory changed to /c:/TOMB/../WINNT ftp> put autoexec.bat %20..%20%20../winnt/2.bat 200 PORT Command successful. 150 Opening ASCII mode data connection for 2.bat. 226 Transfer complete. ftp> dir \..%20.\..%20.\winnt\
