CVE-2006-0507 in Easy CMS
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Easy CMS allow remote attackers to inject arbitrary web script or HTML via (1) unknown attack vectors in the administrative interface and (2) input fields of the contact form.

The vulnerability identified as CVE-2006-0507 represents a critical security flaw in Easy CMS software that exposes the system to cross-site scripting attacks. This type of vulnerability falls under the common weakness enumeration CWE-79 which specifically addresses improper neutralization of input during web page generation in web applications. The flaw manifests in two distinct attack vectors within the content management system's architecture, creating multiple pathways for malicious actors to exploit the platform's security controls.
The technical implementation of this vulnerability occurs through the improper handling of user input within the administrative interface and contact form components of the Easy CMS. When administrators or users submit data through these interfaces, the application fails to adequately sanitize or validate the input before processing or displaying it. This lack of input validation creates opportunities for attackers to inject malicious scripts that can execute in the context of other users' browsers. The attack vectors operate through the web application's failure to implement proper output encoding and input filtering mechanisms, allowing malicious payloads to persist within the system's data storage and subsequently execute when legitimate users interact with the affected pages.
The operational impact of this vulnerability extends beyond simple data corruption or theft, as it provides attackers with persistent access to the system through user sessions and administrative privileges. When successful, these XSS attacks can enable session hijacking, credential theft, and unauthorized access to sensitive administrative functions. The vulnerability's presence in both the administrative interface and contact form components creates a particularly dangerous scenario where attackers could potentially compromise system integrity through either entry point. This dual-vector exposure increases the attack surface and reduces the effectiveness of traditional security controls that might only address one of these interfaces.
Organizations utilizing Easy CMS systems face significant risks when this vulnerability remains unpatched, as it allows for the execution of arbitrary code in the context of authenticated users. The ATT&CK framework categorizes this as a web application attack vector that can lead to privilege escalation and persistent access to target systems. Security professionals should implement immediate mitigations including input validation, output encoding, and web application firewalls to protect against exploitation. The vulnerability highlights the importance of comprehensive security testing and input sanitization across all user-facing components of web applications. Regular security audits and vulnerability assessments should be conducted to identify similar flaws in other system components, as the presence of one XSS vulnerability often indicates potential for additional similar issues throughout the application architecture.
