Summary
by MITRE
Directory traversal vulnerability in modules/hayoo/index.php in Tribisur 2.1, 2.0, and earlier, when magic_quotes_gpc is disabled, allows remote attackers to include and execute arbitrary files via directory traversal sequences in the theme parameter.

The vulnerability identified as CVE-2010-0958 represents a critical directory traversal flaw within the Tribisur content management system versions 2.1 and earlier, specifically affecting the modules/hayoo/index.php component. This security weakness arises from insufficient input validation mechanisms that fail to properly sanitize user-supplied parameters before processing them within the application's file inclusion logic. The vulnerability is particularly dangerous because it can be exploited remotely by attackers without requiring authentication or prior access to the system, making it a significant threat to web application security.
The technical exploitation of this vulnerability occurs through the manipulation of the theme parameter in the URL, where attackers can craft malicious directory traversal sequences such as ../ or ..\ to navigate outside the intended directory structure. When the magic_quotes_gpc directive is disabled on the web server, the application fails to properly escape or filter special characters in user input, allowing the attacker to inject malicious file paths directly into the include statement. This flaw aligns with CWE-22, which classifies directory traversal vulnerabilities as weaknesses that permit unauthorized access to files outside the intended directory scope. The vulnerability demonstrates a classic example of improper input validation where the application directly incorporates user-controllable data into file inclusion operations without adequate sanitization or authorization checks.
The operational impact of this vulnerability extends beyond simple unauthorized file access, as it provides attackers with the capability to execute arbitrary code on the affected system. Successful exploitation can result in complete system compromise, data theft, or the installation of backdoors and malware. Attackers can leverage this vulnerability to access sensitive system files, configuration data, database credentials, and other confidential information stored on the server. The vulnerability also enables privilege escalation attacks where attackers can gain administrative access to the CMS, potentially leading to full control over the website and its underlying infrastructure. This represents a significant concern for organizations relying on Tribisur for their web presence, as the vulnerability can be exploited through simple HTTP requests without requiring advanced technical skills or specialized tools.
The attack surface for this vulnerability is particularly broad given that it affects multiple versions of the Tribisur platform, making it a widespread concern for organizations that have not yet updated their systems. The requirement for magic_quotes_gpc to be disabled creates a specific exploitation condition that security administrators should monitor, as this directive was deprecated in PHP 5.3.0 and removed in PHP 7.0.0, indicating that older systems running vulnerable versions of PHP are more susceptible to this type of attack. Mitigation strategies should include immediate patching of the affected software, enabling proper input validation and sanitization mechanisms, implementing web application firewalls to detect and block malicious traversal attempts, and ensuring that magic_quotes_gpc is not relied upon as the sole security measure. Organizations should also consider implementing least privilege access controls and regular security assessments to identify and remediate similar vulnerabilities in their web applications. The vulnerability demonstrates the importance of following secure coding practices and adhering to the principle of least privilege in web application development, as outlined in various security frameworks and standards including those referenced in the MITRE ATT&CK framework for command and control activities.
