VULHUB ™

Anyone who can execute CGIMailer (anyone who can use the forms that use CGIMailer) can specify what configuration file to use and this can be any file on the system CGIMailer is running on. This allows for the existance of private files to be detected. There are more dangerous implications though: this vulnerability could possibly be exploited to obtain private files from the target system. If there is an FTP server running on the target system on which an attacker has upload priviledges, he/she could upload a malicious configuration file, and then run it using CGIMailer. Configuration files can be used to send files to the attacker via e-mail (among other things).
