A vulnerability has been identified in @Mail, which could be exploited by malicious users to bypass security restrictions and execute arbitrary commands. This flaw is due to an input validation error in the "compose.pl" script that fails to properly validate the "unique" parameter, which could be exploited by malicious users to upload malicious email attachments to arbitrary directories on the server and execute arbitrary commands (e.g. by uploading a Perl file into the webmail directory) with the privileges of the web server.
