CVE-2007-0265 in Portal System Beta
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Ezboxx Portal System Beta 0.7.6 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the pic parameter to custom/piczoom.asp, (2) the nocatname parameter to boxx/user-upload.asp, or (3) the iid parameter to indexes/newscomments.asp.

The CVE-2007-0265 vulnerability represents a critical cross-site scripting flaw affecting the Ezboxx Portal System version 0.7.6 and earlier releases. This vulnerability resides within the web application's input validation mechanisms, specifically targeting three distinct endpoints that process user-supplied parameters without adequate sanitization. The affected system demonstrates a classic lack of proper output encoding and input validation that creates persistent security weaknesses in the application's data handling pipeline.
The technical exploitation of this vulnerability occurs through three primary attack vectors that all stem from insufficient parameter validation in the web application's backend processing. The first vector involves the pic parameter within the custom/piczoom.asp endpoint, where malicious input can be injected and executed when the application displays image-related content. The second vector targets the nocatname parameter in boxx/user-upload.asp, allowing attackers to manipulate category names during file uploads. The third vector exploits the iid parameter in indexes/newscomments.asp, where comment identifiers can be manipulated to inject malicious scripts. These vulnerabilities collectively demonstrate a fundamental flaw in the application's security architecture where user input flows directly into web responses without proper sanitization.
From an operational impact perspective, these XSS vulnerabilities create significant risks for organizations utilizing the Ezboxx Portal System. Attackers can leverage these flaws to execute malicious scripts in the context of authenticated users' browsers, potentially leading to session hijacking, credential theft, or data exfiltration. The vulnerabilities are particularly dangerous because they affect core portal functionality areas including image display, user uploads, and news comment systems, which are commonly accessed by portal users. This creates an attack surface that can be exploited to compromise user sessions and potentially gain elevated privileges within the application's security boundaries.
The vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and represents a clear violation of secure coding practices that should be implemented according to OWASP Top Ten security guidelines. The attack vectors identified in this vulnerability map directly to ATT&CK technique T1531, which involves the use of malicious code to compromise systems. Organizations should implement comprehensive input validation and output encoding mechanisms to prevent such vulnerabilities from being exploited in real-world scenarios, as these flaws can enable attackers to establish persistent access to web applications and their underlying user bases.
Mitigation strategies for CVE-2007-0265 should include immediate patching of the Ezboxx Portal System to a version that addresses these XSS vulnerabilities, combined with implementation of proper input sanitization and output encoding across all affected endpoints. Organizations should also consider deploying web application firewalls to detect and block malicious input patterns, while establishing comprehensive monitoring for suspicious activities that might indicate exploitation attempts. Additionally, regular security assessments should be conducted to identify similar vulnerabilities in other web applications within the organization's infrastructure, as this vulnerability demonstrates a pattern of inadequate security controls that can be replicated across different software systems.
