CVE-2006-5089 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 file parameter. NOTE: the provenance of this information is unknown; the details are obtained from third party information. CVE disputes this vulnerability because the file variable is defined before use in a way that prevents arbitrary inclusion

The vulnerability described in CVE-2006-5089 relates to a potential remote file inclusion flaw in the Jim Plush My-BIC 0.6.5 web application, specifically within the mybic_server.php script. This type of vulnerability falls under the category of insecure direct object references and represents a critical security risk that could allow attackers to execute arbitrary code on the target system. The vulnerability arises from improper input validation and handling of user-supplied data that is directly incorporated into file inclusion operations without adequate sanitization or restriction mechanisms.
The technical flaw manifests when the application processes a file parameter that contains a URL, allowing an attacker to manipulate the inclusion mechanism and load external PHP scripts. This creates an environment where malicious code can be executed with the privileges of the web server process. The vulnerability is classified as a remote file inclusion (RFI) attack vector, which is particularly dangerous because it enables attackers to leverage external resources and potentially gain full control over the affected system. According to CWE-829, this vulnerability represents an incomplete blacklist or inadequate validation of user-provided inputs that can lead to code execution.
The operational impact of this vulnerability extends beyond simple code execution, as it can enable attackers to establish persistent access, escalate privileges, and potentially compromise entire server infrastructures. The remote nature of the attack means that exploitation can occur from anywhere on the internet, making it particularly attractive to malicious actors. From an ATT&CK framework perspective, this vulnerability maps to technique T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter) as attackers can leverage the inclusion mechanism to execute malicious payloads. The security implications are severe enough that organizations should consider this a critical threat requiring immediate remediation.
Despite the disputed nature of this vulnerability as noted in the CVE description, the potential for exploitation remains significant due to the fundamental flaw in input handling. The vulnerability demonstrates how improper parameter validation can create dangerous attack surfaces that allow for arbitrary code execution. Organizations should not rely on the disputed status of this CVE but instead implement robust input validation and sanitization measures to prevent such issues from occurring. The recommended mitigations include implementing strict input validation, using allowlists for file inclusion parameters, and ensuring that all user-supplied data is properly sanitized before being used in file operations. Additionally, the principle of least privilege should be enforced to limit the damage that could occur if such vulnerabilities are exploited.
