Who should care
Developers and administrators using Laravel-Mediable versions before 7.0.0 should be aware of this vulnerability and take immediate action to patch their systems. Additionally, security teams and vulnerability management teams should review the affected scope and severity to prioritize remediation efforts.
Technical summary
The vulnerability in Laravel-Mediable before version 7.0.0 allows attackers to upload files with double extensions, such as shell.php.jpg, which can be executed as PHP code on misconfigured servers. The PATHINFO_FILENAME extraction preserves the inner .php extension, bypassing MIME type, extension, and aggregate type validation checks due to the outer .jpg extension. This can lead to remote code execution on affected systems.
Defensive priority
High
Recommended defensive actions
- Upgrade to Laravel-Mediable version 7.0.0 or later
- Verify and correct server configurations to prevent execution of PHP code in uploaded files
- Implement additional validation and sanitization for uploaded files
- Monitor for suspicious file uploads and system activity
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
