The Flawnter Cleartext Transmission Finder extension is an important addition to the existing Flawnter scan engine. It detects the use of insecure, cleartext transmission protocols such as HTTP, FTP, Telnet, and others. These protocols transmit data without encryption, leaving it vulnerable to interception by attackers. In today's security landscape, ensuring that communications are encrypted is vital for protecting user data, credentials, and other sensitive information from man-in-the-middle attacks. By identifying instances of cleartext transmission, this extension helps organizations enforce security best practices and comply with regulatory standards that mandate secure communication protocols like HTTPS, SFTP, etc. It's very simple to add this extension to Flawnter. First download the extension zip file. Then extract the contents into same folder where the flawnter.jar is. Then add the following line "extension=cleartext-transmission-finder.jar" to flawnter.cfg file. Now when you run Flawnter tool, the extension will also be executed to scan both source code and configuration files for any instances of cleartext transmission usage.
