CVE-2006-2864 in BlueShoes Framework
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in BlueShoes Framework 4.6 allow remote attackers to execute arbitrary PHP code via a URL in the (1) APP[path][applications] parameter to (a) Bs_Faq.class.php, (2) APP[path][core] parameter to (b) fileBrowserInner.php, (c) file.php, and (d) viewer.php, and (e) Bs_ImageArchive.class.php, (3) GLOBALS[APP][path][core] parameter to (f) Bs_Ml_User.class.php, or (4) APP[path][plugins] parameter to (g) Bs_Wse_Profile.class.php.

The CVE-2006-2864 vulnerability represents a critical remote file inclusion flaw within the BlueShoes Framework version 4.6, specifically targeting multiple PHP applications that fail to properly validate user input before incorporating external resources. This vulnerability falls under the category of insecure direct object reference and improper input validation, aligning with CWE-22 and CWE-94 as defined by the Common Weakness Enumeration catalog. The flaw enables malicious actors to inject arbitrary URLs into application parameters, potentially allowing for remote code execution and complete system compromise.
The technical implementation of this vulnerability occurs through multiple entry points within the BlueShoes Framework's core components. Attackers can exploit the vulnerability by manipulating the APP[path][applications] parameter in Bs_Faq.class.php, the APP[path][core] parameter in fileBrowserInner.php, file.php, and viewer.php, or the GLOBALS[APP][path][core] parameter in Bs_Ml_User.class.php, and the APP[path][plugins] parameter in Bs_Wse_Profile.class.php. These parameters are used to dynamically include PHP files, but the framework fails to sanitize or validate the input values, creating opportunities for attackers to inject malicious URLs that point to external code repositories.
The operational impact of this vulnerability extends far beyond simple code execution, as it provides attackers with complete control over the affected systems. Once exploited, attackers can upload and execute malicious PHP scripts, potentially leading to data breaches, system compromise, and unauthorized access to sensitive information. The vulnerability's widespread nature across multiple framework components means that successful exploitation could affect various functionalities including user management, file handling, and content delivery systems. This creates a significant risk for organizations using the BlueShoes Framework, as the attack surface encompasses core application functionalities.
Organizations should implement immediate mitigations including input validation and sanitization of all user-supplied parameters, particularly those used for file inclusion operations. The recommended approach involves implementing strict whitelisting of acceptable paths and parameters, disabling remote file inclusion features, and ensuring that all user inputs are properly validated before being processed. Security professionals should also consider implementing web application firewalls to monitor and block suspicious requests attempting to exploit these parameters. According to the MITRE ATT&CK framework, this vulnerability maps to the T1190 technique for exploiting vulnerabilities in remote services, and the T1059 technique for executing malicious code through command injection. Regular security assessments and code reviews should be conducted to identify similar patterns in other applications, as this vulnerability type remains prevalent in legacy systems. The remediation process should include comprehensive patching of the BlueShoes Framework, along with implementation of proper input validation mechanisms to prevent similar issues from occurring in future software development cycles.
