本来以为去年的春节已经足够不堪了,怎料今年更是难上加难。
第一次在外地过年就遇上疫情爆发的事情,本来计划家人来过年也只能取消了。不过不能出门正好也拥有了大段空闲时间,与其像朋友圈里面的各位花式秀无聊,不如静下心来攻克之前没有完成的一些题目。
This is a challenge from QiangWangBei Finals last year, it’s a RealWorld challenge. Only about 3~4 teams were able to finish it in the game. You can download the challenge files here. The challenge is called VulnTest
, it contains some obvious bugs but the difficulty lies in the exploitation. It was compiled with AddressSanitizer
(ASAN), which is designed to detect the memory corruption thoroughly, so it could provide extra protection for the program. If a vulnerability is triggered, it can be detected as soon as possible and the program died out.
