CVE-2007-3060 in PHPLive
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in PHP Live! 3.2.2 allow remote attackers to inject arbitrary web script or HTML via the (1) sid parameter to (a) chat.php, (2) LANG[DEFAULT_BRANDING] and (3) PHPLIVE_VERSION parameters to (b) help.php, the (4) admin[name] parameter to (c) admin/header.php, and the (5) BASE_URL parameter to (d) super/info.php, and in some cases, the LANG[DEFAULT_BRANDING], PHPLIVE_VERSION, and (6) nav_line parameters to setup/footer.php, different vectors than CVE-2006-6769.

The CVE-2007-3060 vulnerability represents a critical cross-site scripting weakness affecting PHP Live! version 3.2.2, a widely used web-based customer support and live chat system. This vulnerability stems from inadequate input validation and output sanitization mechanisms within the application's core components, creating multiple attack vectors that allow remote threat actors to inject malicious scripts into web pages viewed by other users. The flaw specifically targets several key files including chat.php, help.php, admin/header.php, super/info.php, and setup/footer.php, demonstrating the pervasive nature of the security weakness throughout the application's architecture.
The technical implementation of this vulnerability occurs through improper handling of user-supplied input parameters that are directly reflected in web page output without adequate sanitization or encoding. Attackers can exploit the sid parameter in chat.php to inject malicious scripts that execute in the context of other users' browsers when they view chat sessions. Similarly, the LANG[DEFAULT_BRANDING] and PHPLIVE_VERSION parameters in help.php, along with the admin[name] parameter in admin/header.php, create additional injection points where attacker-controlled content can be executed. The BASE_URL parameter in super/info.php and the nav_line parameter in setup/footer.php further extend the attack surface, allowing for various script injection scenarios that can compromise user sessions and data integrity.
The operational impact of CVE-2007-3060 is significant as it enables attackers to perform session hijacking, defacement of web interfaces, and potentially execute malicious code in users' browsers. This vulnerability directly violates the principle of least privilege and proper input validation as outlined in CWE-79, which specifically addresses cross-site scripting vulnerabilities. The attack vectors align with techniques described in the ATT&CK framework under T1059.005 for command and scripting interpreter, as attackers can leverage these vulnerabilities to execute malicious scripts that may lead to further compromise of the affected systems. Users who interact with the vulnerable PHP Live! application become potential victims of persistent XSS attacks that can persist across multiple sessions and user interactions.
Organizations running vulnerable PHP Live! installations face substantial risk of data breaches, service disruption, and reputational damage when these vulnerabilities are exploited. The attack surface spans across multiple application components, making comprehensive patching essential for mitigating the threat. Security practitioners should implement input validation at multiple layers including application-level sanitization, output encoding, and proper parameter handling. The vulnerability demonstrates the importance of following secure coding practices and adhering to industry standards such as those specified in the OWASP Top Ten, particularly the emphasis on input validation and output encoding to prevent XSS attacks. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other web applications and ensure proper protection against persistent cross-site scripting threats.
