CVE-2006-1623 in FleXiBle Development
Summary
by MITRE
Unspecified vulnerability in main.php in an unspecified "file created by Andries Bruinsma," possibly a FleXiBle Development (FXB) application, allows remote attackers to include and execute arbitrary PHP code. NOTE: this disclosure is extremely vague and has very little information about the specific vulnerability type. In addition, there is little public information on the named product. Finally, an XSS vector is implied in the subject line, but because there is no other information and evidence of a cut-and-paste error, it will not be assigned a separate CVE identifier unless additional information is provided.

This vulnerability resides within a PHP application component named main.php that appears to be part of a FleXiBle Development (FXB) framework or application created by Andries Bruinsma. The unspecified nature of this vulnerability makes it particularly challenging to assess, as the exact technical flaw remains unclear from the available description. The vulnerability classification indicates a remote code execution risk through arbitrary PHP code inclusion, suggesting a critical security flaw that could allow attackers to execute malicious code on the target system. This type of vulnerability typically falls under the category of insecure direct object references or improper input validation, which are commonly associated with CWE-94 and CWE-20 categories in the Common Weakness Enumeration framework.
The technical flaw likely involves improper handling of user-supplied input that gets directly incorporated into PHP include or require statements without adequate sanitization or validation. When an attacker can manipulate parameters that control file inclusion, they can potentially load and execute arbitrary PHP scripts stored on the server or accessible through remote locations. This vulnerability type represents a classic path traversal or code injection attack vector that can be exploited through various means including URL parameters, form submissions, or API calls that are processed by the vulnerable main.php script. The remote aspect of the attack means that exploitation can occur from outside the local network without requiring physical access or prior authentication.
The operational impact of this vulnerability is severe and potentially catastrophic for any system running the affected application. Remote code execution capabilities allow attackers to gain full control over the affected server, potentially leading to data breaches, system compromise, and complete service disruption. Attackers could install backdoors, exfiltrate sensitive data, modify application behavior, or use the compromised system as a launch point for further attacks against internal networks. The lack of specific information about the affected product makes it difficult to determine the exact scope, but such vulnerabilities in core application components like main.php typically affect the entire application stack and can compromise the underlying operating system. The vulnerability's classification aligns with ATT&CK techniques such as T1059.007 for PHP code injection and T1068 for local privilege escalation when combined with other exploitation techniques.
Mitigation strategies for this vulnerability should focus on immediate input validation and sanitization practices. The most effective immediate solution involves implementing proper parameter validation and ensuring that all user inputs used in include or require statements are strictly validated against a whitelist of allowed values. The application should avoid dynamic file inclusion based on user input and instead use static includes with predetermined paths. Additionally, the principle of least privilege should be enforced by running the web application with minimal required permissions and implementing proper access controls. Security headers and input filtering mechanisms should be deployed to prevent malicious payloads from being processed. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities in other components. The absence of specific product information suggests that organizations should perform comprehensive vulnerability assessments across their entire software ecosystem to identify potentially similar flaws in other applications or frameworks that may share similar architectural patterns.
