+# pgAdmin <= 7.6 Authenticated Remote Command Execution (CVE-2023-5002)
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+pgAdmin is a popular and feature rich Open Source administration and development platform for PostgreSQL, the most advanced Open Source database in the world.
+
+A flaw was found in pgAdmin. This issue occurs when the pgAdmin server HTTP API validates the path a user selects to external PostgreSQL utilities such as pg_dump and pg_restore. Versions of pgAdmin prior to 7.7 failed to properly control the server code executed on this API, allowing an authenticated user to run arbitrary commands on the server.

+- <https://github.com/advisories/GHSA-ghp8-52vx-77j4>
+
+## Vulnerable Environment
+
+Execute following command to start a pgAdmin 7.6 server:
+
+```
+docker compose up -d
+```
+
+After the server is started, browse the `http://your-ip:5050` to see the default login page of pgAdmin.
+
+### Something we should know before exploiting the issue
+
+CVE-2023-5002 is a pathes bypass for previous issue [CVE-2022-4223](https://github.com/vulhub/vulhub/tree/master/pgadmin/CVE-2022-4223). There are 2 updates from official patches:
+
+- Added `@login_required` to `validate_binary_path` function, not allowed unauthenticated user to access this API
+- Added `os.path.exists()` to check if the user provided parameter is a valid path
+
+Unfortunately, we can only bypass the second patch, so the CVE-2023-5002 is a authenticated vulerability.
+
+## Exploit
+
+Login the pgAdmin by username `vulhub@example.com` and password `vulhub`.
+
+Select "Tools -> Storage Manager" to open the filemanager dialog:
+
+![](1.png)
+
+Create a new folder which name is a crafted payload `";id;#`:
+
+![](2.png)
+
+Full path of this folder is `/var/lib/pgadmin/storage/vulhub_example.com/";id;#`, we will use this path to complete the exploitation.
+
+Go to "File -> Preferences" to open the setting dialog, open the "Paths -> Binary paths" panel.
+
+Fill the `/var/lib/pgadmin/storage/vulhub_example.com/";id;#` into any field of "PostgreSQL Binary Path" then click validate:

+
+As you can see, the `id` command is executed successful:

+# pgAdmin <= 7.6 后台远程命令执行漏洞（CVE-2023-5002）
+
+pgAdmin是一个著名的PostgreSQL数据库管理平台。
+
+pgAdmin包含一个HTTP API可以用来让用户选择并验证额外的PostgreSQL套件，比如pg_dump和pg_restore。在[CVE-2022-4223](https://github.com/vulhub/vulhub/tree/master/pgadmin/CVE-2022-4223)中，这个API可被用于执行任意命令，官方对此进行了修复，但在7.6版本及以前修复并不完全，导致后台用户仍然可以执行任意命令。

+
+## 漏洞环境
+
+执行如下命令启动一个pgAdmin 7.6服务器：
+
+```
+docker compose up -d
+```
+
+服务器启动后，访问`http://your-ip:5050`即可查看到pgAdmin默认的登录页面。
+
+### 一些值得注意的事情
+
+CVE-2023-5002是一个针对[CVE-2022-4223](https://github.com/vulhub/vulhub/tree/master/pgadmin/CVE-2022-4223)漏洞的补丁绕过漏洞。官方发布了下面两个修复补丁修复漏洞：
+
+- 给`validate_binary_path`函数增加`@login_required`装饰器，限制未授权的用户访问相关接口
+- 使用`os.path.exists()`检查用户传入的路径是否有效
+
+不幸地是，只有第二个修复补丁可以被绕过，所以该漏洞仅是一个后台命令执行漏洞。
+
+## 漏洞复现
+
+使用帐号`vulhub@example.com`和密码`vulhub`登录pgAdmin。
+
+热爱后选择“Tools -> Storage Manager”打开文件管理器：
+
+![](1.png)
+
+创建一个新的目录，名字是我们的Payload `";id;#`：
+
+![](2.png)
+
+这个目录的完整路径是`/var/lib/pgadmin/storage/vulhub_example.com/";id;#`，我们后续就需要使用这个路径来利用漏洞。
+
+选择“File -> Preferences”打开设置页面，并来到“Paths -> Binary paths”面板。在任意一个“PostgreSQL Binary Path”文本框中填入`/var/lib/pgadmin/storage/vulhub_example.com/";id;#`，并点击右侧的“验证”按钮：
+
+![](3.png)
+
+可见，`id`命令被成功执行：
