CVE-2006-5505 in 2BGal
Summary
by MITRE
Multiple PHP file inclusion vulnerabilities in 2BGal 3.0 allow remote attackers to execute arbitrary PHP code via the lang parameter to (1) admin/configuration.inc.php, (2) admin/creer_album.inc.php, (3) admin/changepwd.php.inc, and unspecified other files. NOTE: the provenance of this information is unknown; the details are obtained from third party information.

The vulnerability identified as CVE-2006-5505 represents a critical security flaw in the 2BGal 3.0 web application that exposes multiple PHP file inclusion vulnerabilities. This issue stems from improper input validation and sanitization within the application's file inclusion mechanisms, creating a pathway for remote attackers to execute arbitrary PHP code on the affected system. The vulnerability specifically targets the lang parameter in several administrative files including admin/configuration.inc.php, admin/creer_album.inc.php, and admin/changepwd.php.inc, with additional unspecified files potentially affected. The flaw allows attackers to manipulate the language parameter to include and execute malicious PHP code, effectively bypassing normal access controls and potentially gaining full administrative control over the vulnerable application.
From a technical perspective, this vulnerability manifests as a classic PHP local file inclusion (LFI) or remote file inclusion (RFI) issue, which falls under the CWE-98 weakness category. The root cause lies in the application's failure to properly validate and sanitize user-supplied input before using it in file inclusion operations. When the lang parameter is processed without adequate filtering, attackers can inject malicious file paths or URLs that will be included and executed by the PHP interpreter. This type of vulnerability enables attackers to leverage the application's legitimate file inclusion functionality to load and execute arbitrary code, often leading to complete system compromise. The vulnerability operates at the application layer and can be exploited through HTTP requests that manipulate the lang parameter to point to malicious content.
The operational impact of CVE-2006-5505 is severe and multifaceted, as it provides attackers with the capability to execute arbitrary code on the target system with the privileges of the web server process. Successful exploitation can result in complete system compromise, data theft, unauthorized access to sensitive information, and potential lateral movement within the network. Attackers can use this vulnerability to upload backdoors, establish persistent access, modify application behavior, or gain access to underlying system resources. The administrative nature of the affected files means that successful exploitation could lead to full administrative control over the 2BGal application, potentially allowing attackers to modify configurations, create new user accounts, or manipulate the entire gallery system. This vulnerability also aligns with ATT&CK technique T1505.003 for Lateral Movement and T1059.007 for Command and Scripting Interpreter, as it enables code execution through web-based attack vectors.
Mitigation strategies for CVE-2006-5505 should focus on implementing proper input validation and sanitization measures to prevent malicious input from being processed in file inclusion operations. The most effective approach involves removing or disabling the vulnerable file inclusion functionality entirely, or implementing strict whitelisting of allowed language parameters. Organizations should also consider implementing proper access controls, input validation at multiple layers, and regular security audits of web applications. The vulnerability demonstrates the critical importance of following secure coding practices and input validation principles, as outlined in OWASP Top Ten and the CWE guidelines. Additionally, system administrators should ensure that the 2BGal 3.0 application is updated to a patched version or migrated to a more secure alternative, as this vulnerability represents an outdated application that likely lacks proper security measures and ongoing support. Network segmentation and web application firewalls can provide additional defense-in-depth measures, though the fundamental solution requires addressing the root cause through proper code validation and secure development practices.
