FireFTP add-on for FireFox MLSD and LIST commands directory traversal
|fireftp-mlsd-list-directory-traversal (42516)||Medium Risk|
FireFTP could allow a remote attacker to traverse directories on the system. By persuading a victim to download a directory containing a file with "dot dot" (\..\) sequences in filename via the MLSD or LIST command, an attacker could traverse directories and write arbitrary files to the system.
Upgrade to the latest version of FireFTP (0.98.20080518 or later), available from the FireFTP CVS repository. See References.
