+### CVE
+`CVE-2022-41622, CVE-2022-41800`
+
+### 漏洞描述
+    > 主要是可以利用普通权限的账户，来创建一个root 账户，相当于提权了
+### `exp` 使用
+直接将`exp.rb` 脚本导入`metasploit` 平台即可

+          This creates a local user with a username/password and root-level
+          privileges. Note that a root-level account is not required to do this,
+          which makes it a privilege escalation issue.
+
+          Note that this is pretty noisy, since it creates a user account and
+          creates log files and such. Additionally, most (if not all)
+          vulnerabilities in F5 grant root access anyways.
