CVE-2006-6018 in My-BIC
Summary
by MITRE
PHP remote file inclusion vulnerability in mybic_server.php in Jim Plush My-BIC 0.6.5 allows remote attackers to execute arbitrary PHP code via a URL in the INC_PATH parameter, a different vector than CVE-2006-5089. NOTE: this issue is disputed by CVE and third party researchers because INC_PATH is a constant

The vulnerability described in CVE-2006-6018 pertains to a PHP remote file inclusion flaw discovered in the Jim Plush My-BIC 0.6.5 web application. This vulnerability exists within the mybic_server.php script where the application fails to properly validate or sanitize input parameters before using them in file inclusion operations. The specific parameter of concern is INC_PATH which, when manipulated by an attacker, can be exploited to include arbitrary PHP files from remote locations. This represents a classic remote code execution vulnerability that could potentially allow attackers to execute malicious code on the target system. The vulnerability is classified under CWE-88 due to improper neutralization of special elements used in an expression, specifically in the context of file inclusion operations where external input is directly incorporated into file paths without proper validation.
The technical exploitation of this vulnerability occurs through manipulation of the INC_PATH parameter to point to a remote server hosting malicious PHP code. When the web application processes this parameter, it attempts to include the specified file path, thereby executing the attacker-controlled code within the context of the web server. This attack vector differs from CVE-2006-5089 as it specifically targets the INC_PATH parameter rather than other potential inclusion points within the application. The vulnerability's disputed nature stems from the fact that INC_PATH is implemented as a constant in the application's codebase, which theoretically should not be modifiable by external input. However, the vulnerability report suggests that despite this implementation, the constant can still be manipulated through specific input handling mechanisms.
From an operational perspective, this vulnerability poses significant risks to systems running the affected My-BIC 0.6.5 application. Successful exploitation could allow attackers to gain full control over the web server, execute arbitrary commands, and potentially escalate privileges to access underlying system resources. The impact extends beyond immediate code execution to include potential data breaches, system compromise, and lateral movement within network environments. According to ATT&CK framework, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1059.007 (Command and Scripting Interpreter: PowerShell) as attackers could leverage the remote code execution capability to establish persistent access and maintain control over compromised systems. The vulnerability's classification as a remote file inclusion issue places it within the broader category of injection flaws that are commonly exploited in web application attacks.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and sanitization mechanisms. The most effective approach involves removing or properly escaping user input before it is used in file inclusion operations. Organizations should implement a whitelist approach for file paths and avoid dynamic inclusion of files based on user-supplied parameters. Additionally, disabling remote file inclusion capabilities in PHP configurations and implementing proper access controls can significantly reduce the attack surface. Security measures should also include regular code reviews, vulnerability scanning, and maintaining updated application versions. The ATT&CK framework recommends implementing network segmentation and monitoring for suspicious file inclusion patterns as part of defensive measures. System administrators should also consider implementing web application firewalls and intrusion detection systems to detect and prevent exploitation attempts targeting this specific vulnerability vector.
