Analysis
by VulDB Data Team • 04/09/2025
This vulnerability represents a critical remote file inclusion flaw in SolidState version 0.4 and earlier, classified under CWE-88 as improper neutralization of argument delimiters in a command. The vulnerability exists due to insufficient input validation and sanitization of the base_path parameter within numerous manager/pages/ scripts and module files. Attackers can exploit this weakness by injecting malicious URLs into the base_path parameter, which are then processed by PHP's include or require functions without proper validation, leading to arbitrary code execution. The affected files span across multiple core functionality modules including account management, billing, domain services, hosting services, and administrative configurations, making the attack surface extremely broad.
The technical exploitation mechanism relies on PHP's ability to include remote files when the base_path parameter contains a URL scheme such as http:// or https://. When the application processes user input through these vulnerable scripts, it concatenates the malicious URL directly into the include statement, effectively executing remote PHP code on the server. This vulnerability aligns with ATT&CK technique T1190 for exploitation of remote services and T1059.007 for scripting languages. The attack vector allows for complete server compromise, enabling attackers to execute commands, access sensitive data, install backdoors, or establish persistent access to the vulnerable system.
The operational impact of this vulnerability is severe and multifaceted. Successful exploitation can result in complete system compromise, data breaches, and unauthorized access to sensitive customer information stored within the SolidState application. The widespread nature of affected files means that attackers can target various functional areas including billing systems, user management, domain registration, and hosting services. This vulnerability also poses risks to the underlying infrastructure as attackers can potentially escalate privileges, modify system configurations, or use the compromised server as a launching point for further attacks against other systems. Organizations using affected versions face significant compliance and security risks, particularly in environments handling sensitive financial or personal data.
Mitigation strategies should focus on immediate remediation through patching to version 0.5 or later where the vulnerability has been addressed. Input validation and sanitization must be implemented to prevent URL schemes from being passed through the base_path parameter. The application should employ strict parameter validation using allowlists of acceptable values rather than denylists. Additionally, disabling remote file inclusion in PHP configuration through setting allow_url_include to off provides an additional defense layer. Network segmentation and web application firewalls should be deployed to monitor and block suspicious URL patterns. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other applications. Organizations should also implement proper logging and monitoring to detect potential exploitation attempts and maintain up-to-date security patches for all software components. The vulnerability demonstrates the critical importance of input validation and secure coding practices, particularly when dealing with dynamic file inclusion mechanisms in web applications.
