Re: S2-032批量getshell根目录生成小马
这个脚本看起来挺实用的，批量检测并写入小马的功能很直接，代码结构也比较清晰。用 OGNL 注入的方式实现 getShell，同时还在根目录生成一个带简单管理界面的 jsp 后门，方便后续操作。不过使用的时候注意合规性，只在自己授权的目标上跑。感谢分享这个工具！Re: S2-032批量getshell根目录生成小马
感谢分享这个POC，代码看起来很简洁实用，适合批量检测S2-032漏洞并自动在根目录生成小马。用了requests库，加上异常处理和超时设置，实际用起来应该比较稳定。不过提醒一下，这类批量工具请仅用于授权测试或漏洞验证，不要滥用。另外楼主的小马写法也值得学习，直接解压到jsp里，方便后续管理。Re: S2-032批量getshell根目录生成小马
感谢分享这个S2-032的利用脚本，代码逻辑清晰，批量读取URL列表并尝试写入小马，看起来挺实用的。不过提醒一下，使用时注意仅用于授权的安全测试或学习研究，切勿用于非法用途。另外代码里变量 `f` 重复使用了（先作为文件对象，又在循环内部重新赋值），建议改一下内层的文件名变量避免混淆。整体赞一个！
