CVE-2008-2133 in Nukeet
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in the Journal module in Tru-Zone Nuke ET 3.x allows remote attackers to inject arbitrary web script or HTML via the title parameter in a new entry, as demonstrated by a CSS property in the STYLE attribute of a DIV element, a different vulnerability than CVE-2008-1873.

The vulnerability identified as CVE-2008-2133 represents a critical cross-site scripting flaw within the Journal module of Tru-Zone Nuke ET version 3.x software. This security weakness specifically manifests when the application fails to properly sanitize user input submitted through the title parameter during new entry creation processes. The flaw enables malicious actors to inject arbitrary web scripts or HTML content directly into the application's output, creating persistent security risks for all users interacting with the vulnerable system. The vulnerability operates at the application layer and specifically targets the input validation mechanisms that should prevent malicious code execution within the web interface.
The technical implementation of this XSS vulnerability occurs through the manipulation of the title parameter in journal entry submissions. Attackers can exploit this weakness by embedding malicious code within the title field, particularly utilizing CSS properties within the STYLE attribute of DIV elements. This approach demonstrates a sophisticated understanding of how browser rendering engines process CSS and HTML content, allowing the injected code to execute within the context of other users' browsers. The vulnerability differs from CVE-2008-1873 in its specific exploitation vector and target parameter, indicating multiple distinct XSS pathways within the same software module. This particular variant leverages the browser's interpretation of CSS style attributes to execute malicious scripts, bypassing standard input sanitization measures.
The operational impact of CVE-2008-2133 extends beyond simple data theft or defacement, as it creates persistent security risks for all users of the vulnerable Tru-Zone Nuke ET system. When victims view journal entries containing malicious code, their browsers execute the injected scripts, potentially leading to session hijacking, credential theft, or redirection to malicious websites. The vulnerability affects the entire user base since the malicious code executes within the context of legitimate user sessions, making it particularly dangerous for applications handling sensitive information. The persistence of this vulnerability means that once exploited, the malicious code continues to affect users until the application is patched or the affected entries are removed, creating ongoing security exposure.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-79 which defines Cross-Site Scripting as a weakness that allows attackers to inject client-side scripts into web applications. The ATT&CK framework categorizes this as a technique for Code Injection and potentially as a method for Initial Access through malicious web content. Organizations using Tru-Zone Nuke ET 3.x should implement immediate mitigations including input validation and output encoding of all user-provided content, particularly within the Journal module. The recommended approach involves implementing strict sanitization of all input parameters, including the title field, and employing Content Security Policy headers to prevent execution of unauthorized scripts. Additionally, regular security audits and application penetration testing should be conducted to identify similar vulnerabilities in other modules and prevent similar issues from arising in the future.
