The CVE-2010-4877 vulnerability represents a classic cross-site scripting flaw in the OneCMS content management system version 2.6.1. This vulnerability resides within the index.php script and specifically targets the view parameter handling mechanism. The flaw allows remote attackers to inject malicious web scripts or HTML code into the application's response, creating a persistent security risk that can be exploited without requiring any authentication or privileged access. The vulnerability demonstrates a critical failure in input validation and output encoding practices within the CMS framework, making it particularly dangerous for websites that rely on user-generated content or dynamic page rendering.
The technical implementation of this XSS vulnerability stems from improper sanitization of user-supplied input parameters. When the view parameter is processed by the index.php script, the application fails to adequately validate or escape the input before incorporating it into the HTML response. This creates an injection point where malicious actors can craft payloads that execute in the context of other users' browsers. The vulnerability can be exploited through various vectors including reflected, stored, or DOM-based XSS scenarios depending on how the application handles the injected content. According to CWE classification, this corresponds to CWE-79 which specifically addresses Cross-site Scripting vulnerabilities where insufficient input validation allows malicious scripts to be executed in web applications.
The operational impact of CVE-2010-4877 extends beyond simple script injection, as it can enable attackers to perform session hijacking, deface websites, steal sensitive user information, or redirect victims to malicious domains. Attackers can leverage this vulnerability to create persistent backdoors, harvest cookies, or execute unauthorized administrative actions if they can gain access to privileged user sessions. The vulnerability affects any website running OneCMS 2.6.1 that processes user input through the view parameter, making it particularly concerning for content management systems that handle diverse user interactions. Organizations using this vulnerable software face significant risks including data breaches, reputational damage, and potential compliance violations under various regulatory frameworks such as PCI DSS, HIPAA, or GDPR.
Mitigation strategies for this vulnerability should include immediate patching of the OneCMS software to the latest version that addresses the XSS flaw, implementing proper input validation and output encoding mechanisms, and deploying web application firewalls to detect and block malicious payloads. Security teams should conduct comprehensive vulnerability assessments to identify other potential injection points within the application and establish robust input sanitization protocols. The remediation process should follow established security practices including the principle of least privilege, regular security updates, and comprehensive testing of all user input handling mechanisms. Organizations should also implement monitoring solutions to detect anomalous user behavior patterns that might indicate exploitation attempts. According to ATT&CK framework methodology, this vulnerability would be categorized under T1059.001 for command and script injection techniques, highlighting the need for comprehensive defensive measures across multiple security domains including network monitoring, application security, and user behavior analytics.
