SuiteCRM Auth RCE (CVE-2022-23940)
cve-2022 | Level: Easy | Total Lab Runs: 0 | Premium Lab |
In this lab environment, the user will access a Kali GUI instance. A vulnerable machine SuiteCRM server deployed on 10.0.X.X. The IP address of the target machine is provided in a text file named target placed on the Desktop of the Kali machine (/root/Desktop/target).
In 2022, a high-risk vulnerability was found in the SuiteCRM. SuiteCRM 7.12.1 and 8.x through 8.0.1 is vulnerable to remote code execution. Authenticated users with access to the Scheduled Reports module can achieve this by leveraging PHP deserialization in the email_recipients property. By using a crafted request, they can create a malicious report, containing a PHP-deserialization payload in the email_recipients field. Once someone accesses this report, the backend will deserialize the content of the email_recipients field and the payload gets executed. Project dependencies include a number of interesting PHP deserialization gadgets (e.g., Monolog/RCE1 from phpggc) that can be used for Code Execution.Your task is to fingerprint the application using command-line tools available on the Kali terminal and then exploit the application using the appropriate Metasploit module. Get a meterpreter shell on the target.

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email attackdefense@pentesteracademy.com clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
