The vulnerability identified as CVE-2007-1977 represents a critical cross-site scripting flaw within the holaCMS content management system version 1.4.10. This security weakness resides in the index_cms.php script and specifically affects the acuparam parameter handling mechanism. The flaw enables remote attackers to execute malicious web scripts or HTML code within the context of other users' browsers, potentially compromising the integrity of the web application and its user base.
This vulnerability falls under the CWE-79 category of Cross-Site Scripting, which is classified as a critical weakness in web application security. The issue occurs when the application fails to properly validate or sanitize user input before incorporating it into dynamically generated web pages. In the case of holaCMS, the acuparam parameter does not undergo adequate input sanitization, allowing attackers to inject malicious payloads that get executed when other users view the affected pages. The vulnerability is particularly concerning because it operates at the application layer, affecting the web interface directly and potentially enabling further attacks such as session hijacking or data theft.
The operational impact of this vulnerability extends beyond simple script injection, as it can be leveraged for more sophisticated attacks within the context of the ATT&CK framework. An attacker could exploit this weakness to steal user sessions, redirect victims to malicious websites, or even modify content displayed to users. The remote nature of the attack means that exploitation does not require physical access to the system or any special privileges, making it particularly dangerous in environments where the CMS is widely used. The vulnerability affects all users who interact with the affected holaCMS installation, potentially compromising thousands of users if the system is publicly accessible.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and output encoding mechanisms. The primary defense involves sanitizing all user-supplied input, particularly parameters like acuparam, before they are processed or displayed in web pages. This includes implementing proper HTML entity encoding for any data that will be rendered in the browser context. Additionally, developers should adopt a whitelist approach for parameter validation, ensuring that only expected and safe input values are accepted. Security patches should be applied immediately to upgrade to a fixed version of holaCMS, as this vulnerability has been known since 2007 and likely has multiple remediation options available through official updates. Organizations should also implement proper web application firewalls and input validation rules to detect and prevent such injection attempts, while maintaining regular security assessments to identify similar weaknesses in other components of their web infrastructure.
