CVE-2007-2196 in jambook
Summary
by MITRE
** DISPUTED ** PHP remote file inclusion vulnerability in jambook.php in the Jambook (com_Jambook) 1.0 beta7 module for Mambo and Joomla! allows remote attackers to execute arbitrary PHP code via a URL in the mosConfig_absolute_path parameter. NOTE: this issue has been disputed by a reliable third party because the jambook.php protects against direct request.

The vulnerability identified as CVE-2007-2196 represents a remote file inclusion flaw that was originally reported in the Jambook module version 1.0 beta7 for Mambo and Joomla! platforms. This type of vulnerability falls under the category of insecure direct object references and remote code execution risks that have been extensively documented in cybersecurity literature. The flaw specifically resides in the jambook.php file where the mosConfig_absolute_path parameter is processed without adequate input validation or sanitization, creating an opportunity for malicious actors to inject and execute arbitrary PHP code on vulnerable systems.
The technical implementation of this vulnerability demonstrates a classic remote file inclusion attack vector where an attacker can manipulate the mosConfig_absolute_path parameter to include malicious URLs. This parameter typically expects a local file path but when improperly handled, allows remote attackers to specify external URLs that contain malicious PHP code. The vulnerability operates at the application layer and can be classified under CWE-88, which describes improper neutralization of special elements used in an OS command, or more specifically under CWE-94 when it results in arbitrary code execution. The attack mechanism leverages the lack of proper parameter validation and the trust placed in user-supplied input, creating a path for remote code execution that could lead to complete system compromise.
From an operational impact perspective, this vulnerability poses significant risks to web applications running vulnerable versions of the Jambook module. The ability to execute arbitrary PHP code remotely means that attackers could potentially gain full control over affected servers, extract sensitive data, modify content, or establish persistent backdoors. The vulnerability affects not only the targeted application but also the underlying infrastructure, as successful exploitation could lead to broader network compromise and data breaches. Organizations running these vulnerable systems face potential regulatory compliance violations and reputational damage when such vulnerabilities are exploited in the wild.
The disputed nature of this CVE highlights the complexity of vulnerability assessment and the importance of thorough validation before assigning severity ratings. According to industry standards and ATT&CK framework analysis, the disputed status suggests that the vulnerability may not be exploitable under normal circumstances due to protective measures in place. However, the original report indicates that the jambook.php file was designed to protect against direct requests, which implies that the vulnerability might only be exploitable through specific attack vectors or when additional security controls are bypassed. This situation underscores the need for comprehensive security assessments and proper input validation mechanisms that align with NIST cybersecurity frameworks and OWASP top ten security risks. Mitigation strategies should include implementing proper parameter validation, using secure coding practices, and ensuring that all user-supplied inputs are properly sanitized and validated before processing. Organizations should also consider implementing web application firewalls and regularly updating their software to patch known vulnerabilities while maintaining proper security monitoring and incident response procedures.
