A proof-of-concept exploit for CVE-2025-49113, a remote code execution vulnerability in Roundcube Webmail.
Description
This exploit targets a deserialization vulnerability in Roundcube Webmail versions 1.5.0 through 1.6.10. The vulnerability allows an authenticated attacker to execute arbitrary code on the server.
Vulnerable Versions
- 1.5.0 - 1.5.9
- 1.6.0 - 1.6.10
Requirements
- PHP 7.0 or higher
- cURL extension enabled
- Target running a vulnerable version of Roundcube
Usage
php CVE-2025-49113.php <url> <username> <password> <command>
Parameters
<url>
: The base URL of the Roundcube installation (e.g., http://localhost/roundcube/)<username>
: Roundcube username<password>
: Roundcube password<command>
: Command to execute on the target system
Example
php CVE-2025-49113.php http://localhost/roundcube/ admin password "id"

How it Works
- The script first checks if the target is running a vulnerable version of Roundcube
- If vulnerable, it proceeds with the authentication process
- After successful authentication, it sends a generic PNG image to the server
- During the upload, the exploit performs two injections:
- PHP session injection through the "_form" parameter in the query string
- Malicious object (gadget) injection through the "filename" parameter of "_file"
- The combination of these injections allows for remote code execution on the server
Notes
- The exploit requires valid credentials to work
- The target must be running a vulnerable version of Roundcube
