CVE-2006-2816 in coolphp magazine
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in index.php in coolphp magazine allow remote attackers to inject arbitrary web script or HTML via the (1) op and (2) nick parameters, and possibly the (3) 0000, (4) userinfo, (5) comp_der, (6) encuestas, and (7) pagina parameters. NOTE: it is not clear whether this is a distributable product or a site-specific vulnerability. If it is site-specific, then it should not be included in CVE.

The vulnerability identified as CVE-2006-2816 represents a critical cross-site scripting flaw discovered in the index.php script of coolphp magazine software. This vulnerability manifests through multiple attack vectors, specifically targeting the op and nick parameters which can be manipulated by remote attackers to inject malicious web scripts or HTML content. The flaw extends to several additional parameters including 0000, userinfo, comp_der, encuestas, and pagina, creating multiple entry points for potential exploitation. The nature of this vulnerability places it squarely within the CWE-79 category of Cross-Site Scripting, which is classified as a fundamental web application security weakness that allows attackers to execute malicious scripts in the context of other users' browsers.
The technical implementation of this vulnerability exploits the improper sanitization of user input within the coolphp magazine application's index.php file. When users submit data through the affected parameters, the application fails to adequately validate or escape the input before processing or displaying it in web pages. This lack of input validation creates an environment where attackers can embed malicious code that executes in the browsers of other users who view the affected content. The vulnerability's impact is amplified by the fact that multiple parameters are affected, increasing the attack surface and providing multiple opportunities for exploitation. According to ATT&CK framework, this vulnerability maps to T1059.008 for Scripting and T1566.001 for Phishing, as it enables attackers to deliver malicious payloads through web-based vectors.
The operational impact of this vulnerability is significant for any organization or individual using the coolphp magazine software. Remote attackers could potentially execute arbitrary code on victim machines, steal session cookies, perform unauthorized actions on behalf of users, or redirect users to malicious websites. The site-specific nature of this vulnerability raises questions about its broader applicability, though the potential for exploitation remains high given the nature of XSS attacks. The vulnerability affects the integrity and confidentiality of user data, as well as the availability of the application's services. Organizations relying on this software face risks of data breaches, unauthorized access, and potential compromise of user accounts. The attack vector through web browsers means that any user interacting with the vulnerable application could become a victim, making this a particularly concerning security weakness.
Mitigation strategies for CVE-2006-2816 should focus on comprehensive input validation and output encoding practices. The primary defense mechanism involves implementing strict validation of all user-supplied input parameters, particularly those used in the affected op, nick, and other identified parameters. Organizations should implement proper HTML escaping and encoding techniques when displaying user-generated content to prevent script execution. The implementation of Content Security Policy (CSP) headers can provide additional protection layers against XSS attacks by controlling which sources of content can be executed within the browser. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components. Given the age of this vulnerability, organizations should consider upgrading to modern, secure versions of the software or implementing web application firewalls as additional protective measures. The vulnerability highlights the importance of following secure coding practices and input sanitization as outlined in OWASP Top Ten and other industry security standards to prevent such critical weaknesses from persisting in web applications.
