CVE-2020-5221: Troglobit Uftpd

High severity, CVSS 7.2. EPSS: 1.2% chance of exploitation in the next 30 days.

In uftpd before 2.11, it is possible for an unauthenticated user to perform a directory traversal attack using multiple different FTP commands and read and write to arbitrary locations on the filesystem due to the lack of a well-written chroot jail in compose_abspath(). This has been fixed in version 2.11
