Description Riccardo Schirone 2018-07-31 13:15:14 UTC 
Improperly sanitized remote file names in lftp, up to version 4.8.3, may lead to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim' system.
