CVE-2006-1413 in EZHomepagePro
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in EZHomepagePro 1.5 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) adid or (2) aname parameter in (a) common/email.asp, (b) users/users_search.asp, or (c) users/users_profiles.asp; (3) page parameter in (d) users/users_calendar.asp; (4) usid parameter in (e) users/users_mgallery.asp; or (5) m parameter in (f) users/users_search.asp.

The vulnerability described in CVE-2006-1413 represents a critical cross-site scripting flaw affecting EZHomepagePro version 1.5 and earlier, demonstrating a fundamental failure in input validation and output encoding practices within web applications. This vulnerability resides in multiple script files across the application's user management and content display modules, specifically targeting parameters that are directly incorporated into web responses without proper sanitization. The affected parameters include adid and aname in email.asp, users_search.asp, and users_profiles.asp, along with page in users_calendar.asp, usid in users_mgallery.asp, and m in users_search.asp, indicating a systemic weakness in the application's data handling mechanisms.
The technical exploitation of this vulnerability occurs when remote attackers submit malicious payloads through these vulnerable parameters, which are then reflected back to users' browsers without adequate filtering or encoding. This creates an environment where attackers can inject arbitrary JavaScript code or HTML content that executes in the context of other users' sessions, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of victims. The vulnerability is classified under CWE-79 as "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", which is one of the most prevalent and dangerous web application security flaws documented in the CWE database.
From an operational perspective, this vulnerability poses significant risks to organizations using EZHomepagePro, as it allows attackers to compromise user sessions and potentially escalate privileges within the application. The impact extends beyond simple data theft to include potential account takeover scenarios where malicious scripts could capture user credentials or manipulate application functionality. The attack surface is particularly concerning given that the vulnerable parameters are accessible through multiple endpoints, increasing the probability of successful exploitation. This vulnerability aligns with ATT&CK technique T1531 for "Account Access Removal" and T1071.001 for "Application Layer Protocol: Web Protocols" when considering the attack vectors and potential lateral movement opportunities.
Organizations should implement immediate mitigations including comprehensive input validation and output encoding across all user-supplied parameters, particularly those used in dynamic content generation. The application should employ proper HTML escaping mechanisms for all parameters before rendering them in web responses, and implement Content Security Policy headers to limit script execution capabilities. Additionally, regular security code reviews should be conducted to identify similar patterns in other application components, as this vulnerability demonstrates a lack of consistent security practices throughout the codebase. The remediation process must include thorough parameter validation, proper sanitization of user inputs, and implementation of a robust security framework that addresses the root cause of the XSS vulnerability rather than merely patching individual instances.
