CVE-2006-3052 in Event Registration Paypal
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in Event Registration allows remote attackers to inject arbitrary web script or HTML via the (1) event_id parameter to view-event-details.php or (2) select_events parameter to event-registration.php. NOTE: the provenance of this information is unknown; the details are obtained from third party information.

This cross-site scripting vulnerability exists in event registration systems where user input is not properly sanitized before being rendered back to users. The flaw manifests in two primary attack vectors within the web application's event management functionality. Attackers can exploit this weakness by injecting malicious scripts through the event_id parameter in the view-event-details.php script or through the select_events parameter in the event-registration.php script. These parameters serve as entry points where unvalidated user input flows directly into the application's output rendering mechanism without adequate sanitization or encoding.
The technical nature of this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. This weakness allows attackers to execute malicious scripts in the context of other users' browsers, potentially leading to session hijacking, credential theft, or data manipulation. The vulnerability operates at the application layer where input validation and output encoding controls fail to prevent malicious code from being executed in the victim's browser environment. The attack requires no special privileges and can be executed through standard web browser interactions, making it particularly dangerous as it can be exploited by anyone with access to the vulnerable application.
The operational impact of this vulnerability extends beyond simple script injection, as it can enable attackers to perform a wide range of malicious activities within the compromised application's context. An attacker could potentially steal session cookies, redirect users to malicious sites, modify page content to deceive users, or even escalate privileges within the application. The vulnerability affects the core event registration functionality, which likely handles sensitive user data including personal information, registration details, and potentially payment information. This makes the attack surface particularly valuable for cybercriminals seeking to exploit user trust in event registration systems.
Security mitigations for this vulnerability should focus on implementing robust input validation and output encoding mechanisms throughout the application's data flow. The recommended approach involves sanitizing all user-provided input parameters, particularly those used in dynamic content generation, through proper encoding techniques such as HTML entity encoding or JavaScript escaping. Additionally, implementing a Content Security Policy (CSP) can provide an additional layer of protection by restricting the sources from which scripts can be executed. The application should also employ proper parameter validation to ensure that event_id and select_events parameters contain only expected data types and values. This vulnerability demonstrates the critical importance of following secure coding practices and adhering to the principle of least privilege in web application development, as outlined in various security frameworks including those referenced in the ATT&CK framework for web application attacks. Organizations should also implement regular security testing including dynamic application security testing and manual penetration testing to identify similar vulnerabilities before they can be exploited by threat actors.
