Details
This advisory discloses a vulnerability within the FTP client in AceFTP. When exploited, this vulnerability allows an anonymous attacker to write files to arbitrary locations on a Windows user's system. The FTP client does not properly sanitise filenames containing directory traversal sequences (forward-slash) that are received from an FTP server in response to the LIST command. An example of such a response from a malicious FTP server is shown below. Response to LIST (forward-slash): -rw-r--r-- 1 ftp ftp 20 Mar 01 05:37 /../../../../../../../../../testfile.txt\r\n By tricking a user to download a directory from a malicious FTP server that contains files with fowward-slash directory traversal sequences in their filenames, it is possible for the attacker to write files to arbitrary locations on a user's system with privileges of that user. An attacker can potentially leverage this issue to write files into a user's Windows Startup folder and execute arbitrary code when the user logs on.

Home Sweet Home Alone (2021) is the holiday reboot that tried to recapture the slapstick spirit of the original Home Alone while dressing it in modern clothes — streaming release, new kid hero, and a contemporary twist on attic-bound mischief. The film centers on Max, a clever but sometimes lonely kid who’s left behind when his family rushes off on holiday. When a pair of bumbling thieves target the household, Max turns the house into a booby-trapped fortress with the same gleeful inventiveness that made the original a seasonal favorite. home sweet home alone 2021 9kmazacom hindi dua install
