| Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |

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.

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.
