Kaltura Remote PHP Code Execution
Description
This module exploits an Object Injection vulnerability in Kaltura. By exploiting this vulnerability, unauthenticated users can execute arbitrary code under the context of the web server user. Kaltura has a module named keditorservices that takes user input and then uses it as an unserialized function parameter. The constructed object is based on the SektionEins Zend code execution POP chain PoC, with a minor modification to ensure Kaltura processes it and the Zend_Log function's __destruct() method is called. Kaltura versions prior to 11.1.0-2 are affected by this issue. This module was tested against Kaltura 11.1.0 installed on CentOS 6.8.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
