Therefore, we can use ROPgadget tool to obtain the code fragments that we can exploit, and use pwntool to exploit the vulnerabilities of vulnerable programs, thus achieving our attack purpose, that is, running system ("/bin/sh"). In order to facilitate the subsequent use of ROPgadget tool to find gadget and attack, it is necessary to copy the libc.so.6 file to the operation directory. First, use the "ldd" command to view the source directory, and then use the "cp" command to copy it to the operation directory.The company conducted a questionnaire, I found that people still agree with the questionnaire, All the things they usually don't want to say are written out in the questionnaire, and they can also express their dissatisfaction to their heart's content.
