CVE-2008-6287 in Broadcast Machine
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in Broadcast Machine 0.1 allow remote attackers to execute arbitrary PHP code via a URL in the baseDir parameter to (1) MySQLController.php, (2) SQLController.php, (3) SetupController.php, (4) VideoController.php, and (5) ViewController.php in controllers/.

The vulnerability identified as CVE-2008-6287 represents a critical remote file inclusion flaw affecting the Broadcast Machine 0.1 content management system. This vulnerability resides in the application's controller files and stems from inadequate input validation mechanisms that fail to properly sanitize user-supplied parameters before incorporating them into file inclusion operations. The specific flaw manifests in five distinct controller files including MySQLController.php, SQLController.php, SetupController.php, VideoController.php, and ViewController.php, all located within the controllers/ directory structure of the affected system.
The technical implementation of this vulnerability allows malicious actors to manipulate the baseDir parameter through HTTP requests, enabling them to inject arbitrary URLs that the application then attempts to include and execute as PHP code. This type of vulnerability directly maps to CWE-88, which describes improper neutralization of argument delimiters in a command or query, and more specifically aligns with CWE-94, representing improper execution of code in the context of a command or query. The flaw operates by bypassing normal input validation checks and leveraging the application's legitimate file inclusion functionality to load and execute malicious code from remote servers.
From an operational perspective, this vulnerability presents a severe risk to systems running the affected Broadcast Machine version, as it allows remote code execution without requiring authentication or prior access to the system. Attackers can leverage this weakness to gain complete control over the affected server, potentially leading to data breaches, service disruption, or further lateral movement within network environments. The impact extends beyond immediate code execution capabilities, as it provides attackers with persistent access to the compromised system and enables them to establish backdoors, exfiltrate sensitive data, or use the compromised server as a launch point for attacks against other systems.
The attack surface for this vulnerability encompasses any network endpoint that accepts user input through the baseDir parameter in the specified controller files, making it particularly dangerous in web applications that process external inputs. Organizations should consider this vulnerability in the context of the ATT&CK framework, specifically under the T1190 technique for Exploit Public-Facing Application and T1059 for Command and Scripting Interpreter, which describes how attackers can leverage such vulnerabilities to execute malicious code. Mitigation strategies must include immediate patching of the affected application, implementation of input validation controls, and deployment of web application firewalls to detect and block malicious requests attempting to exploit this vulnerability. Additionally, organizations should conduct comprehensive security assessments to identify similar vulnerabilities in other applications and establish robust monitoring procedures to detect unauthorized access attempts targeting this class of vulnerability.
