Cache overflow detection tool BED

Cache overflow (Buffer Overflow) is a common vulnerability, which widely exists in a variety of operating systems and software. The use of cache overflow vulnerabilities will lead to program failure and system crash. Penetration testers can take advantage of these vulnerabilities to obtain system permissions and execute commands remotely. The BED tool (Bruteforce Exploit Detector) provided by Kali Linux is a cache vulnerability detection tool. It has eleven plug-ins preset. These plug-ins target different services or systems, such as FTP, SMTP, POP, and so on. At the same time, these plug-ins contain various known attack payloads.

BED sends attack data to the target host by loading plug-ins. If the target is found to be unresponsive, there may be an overflow zone vulnerability in the target. After many tests and verification, the location of the vulnerability can be determined. Then manually perform verification, code review, decompilation and other ways, you can find out the specific trigger mechanism of the vulnerability, so as to exploit.
