The vulnerability identified as CVE-2008-2979 represents a critical cross-site scripting flaw within the Ourvideo CMS 9.5 content management system, specifically affecting the phpi/login.php component. This issue exposes the system to remote code execution risks where malicious actors can inject arbitrary web scripts or HTML content directly into the application's user interface. The vulnerability manifests through two distinct parameter injection points: top_page and end_page, which are processed without adequate input validation or output sanitization mechanisms. These parameters likely serve legitimate purposes within the application's navigation or page rendering logic, but their improper handling creates exploitable entry points for attackers seeking to compromise user sessions or redirect victims to malicious content.
The technical exploitation of this vulnerability aligns with CWE-79, which categorizes cross-site scripting vulnerabilities as weaknesses in input validation and output sanitization. Attackers can craft malicious payloads containing script tags or javascript code within the affected parameters, which then get executed in the browsers of unsuspecting users who access the compromised pages. This type of vulnerability falls under the ATT&CK framework's T1059.007 technique for "Command and Scripting Interpreter: JavaScript," as it enables the execution of malicious javascript code through web-based interfaces. The impact extends beyond simple script injection to potentially enable session hijacking, credential theft, or redirection to phishing sites, making it particularly dangerous for user authentication systems.
The operational implications of this vulnerability are severe for organizations utilizing Ourvideo CMS 9.5, as it compromises the integrity of user sessions and potentially exposes sensitive authentication data. Users who authenticate through the vulnerable login component may have their sessions compromised, leading to unauthorized access to protected content or administrative functions. The vulnerability's remote nature means attackers do not require physical access to the system or network to exploit it, making it particularly attractive for widespread attacks. Organizations running this CMS version face elevated risk of data breaches, user account takeovers, and potential lateral movement within their network infrastructure if the compromised system serves as a foothold for further attacks.
Mitigation strategies should focus on immediate patching of the CMS to address the input validation gaps in the phpi/login.php script, ensuring that all user-supplied parameters undergo proper sanitization and validation before processing. Implementing a robust web application firewall with XSS detection capabilities provides an additional layer of protection, while regular security audits of web applications should include thorough parameter validation testing. The remediation process must also involve comprehensive input filtering that strips or encodes potentially dangerous characters, particularly those used in script injection attempts such as angle brackets, script tags, and javascript protocols. Organizations should also consider implementing content security policies to restrict script execution and monitor for unusual parameter patterns that might indicate attempted exploitation attempts.
