CVE-2019-9649
Using the MDTM FTP command, a remote attacker can use a directory traversal technique (..\..\) to browse outside the root directory to determine the existence of a file on the operating system, and its last modified date.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 14.5%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
