overflow21.今天本地部署了大模型claude一句话直接解出来flag,惊呆了老铁题目叫做overflow2是一道pwn题目下载下来是一个压缩包pwn5.zip,启动了一个环境nc 160...161 124502.本地安装pwn环境还报错3.看到报错你肯定觉得我没有升级pip但是我升级了还在报错python -m pip install --upgrade pip4.没有办法我把报错直接复制给AI它直接给我换了思路直接写成exp给我获取flag本地下载环境报错C:\Users\Dell.claude\skills\ctf-skills\ctf-workspace\overflow2pip install pwntoolsDefaulting to user installation because normal site-packages is
