CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| 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.

# Soft : FTP Serv-U
# Version : v7.4.0.1
#
# A vulnerability is caused due to an input validation error when handling FTP "MKD"
# requests. This can be exploited to escape the FTP root and create arbitrary directory on
# the system via directory traversal attacks using the "\.." character sequence.
