The application is to detect the existence of remote/local stack-based buffer overflow vulnerabilities using the standard communication protocol for each service. The application allows to customize the testing mechanism of each service through templates. These templates are simply plain text files, which accept some kind of special words (see STF section) These files are stored in the folder with a direct association between the protocol and the template and with the extension STF (Service Tester File) Currently, the application version 2.1 supports the FTP, POP3 and SMTP protocol.”]
