For the convenience of the experiment, we directly use the functions in libc.so.6 as the attack functions to be executed. This is a C program runtime in Linux, which holds a large number of available functions and contains system ("/bin/sh"). 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.民国初年上海滩军阀混战，赌界枭雄一手遮天。小老千高达拜落魄的赌界圣手为师，在警长的帮助下进行了一段奇葩的训练，练就一身本领。为救心爱女人与枭雄展开殊死斗争，各势力战争一触即发，上海滩再度陷入混乱，上演了一出生死与爱情的挽歌 ……爱国医生刘云翔利用和查理的师生关系，打进中美医院，保护国宝北京猿人头盖骨化石免遭日军掠夺，与军统人员并肩作战，刺杀为盗取国宝而来的天皇特使，完成了组织的任务，刘也加入了中国共产党，并成长为一名抗日战士。哦？徐荣略微的沉吟之后问道：怎么？你的意思是？徐建说道：周浩匆匆忙忙前去自然是收到了消息，去会稽山寻小妹去了。同一时刻，离这里几百公里的省监狱，国际刑警组织挂牌通缉多年If an event is no longer needed, we can delete it with a drop event statement.
