CVE-2020-5221

Name of the Vulnerable Software and Affected Versions uftpd versions prior to 2.11

Description The issue allows an unauthenticated user to perform a directory traversal attack using multiple different FTP commands, enabling them to read and write to arbitrary locations on the filesystem. This is due to the lack of a well-written chroot jail in the compose abspath() function.

Recommendations For versions prior to 2.11, update to version 2.11 to resolve the issue. As a temporary workaround, consider restricting access to the FTP server until the update can be applied.
