CVE-2002-1829 in OpenBB
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in codeparse.php in Open Bulletin Board (OpenBB) 1.0.0 RC3 allows remote attackers to inject arbitrary web script or HTML via (1) myhome.php, (2) an onerror attribute in an IMG tag (a variant of CVE-2002-0330), or (3) a glow tag.

The cross-site scripting vulnerability identified as CVE-2002-1829 affects Open Bulletin Board version 1.0.0 RC3 and resides within the codeparse.php component of the application. This vulnerability represents a classic persistent XSS flaw that enables remote attackers to execute malicious scripts within the context of other users' browsers. The vulnerability manifests through multiple attack vectors including interactions with myhome.php, IMG tag onerror attributes, and glow tag implementations, demonstrating the complexity and breadth of potential exploitation methods. The flaw stems from insufficient input validation and output sanitization mechanisms within the bulletin board's code parsing functionality, creating opportunities for malicious code injection that can persist across user sessions.
The technical implementation of this vulnerability aligns with CWE-79, which specifically addresses Cross-Site Scripting flaws in web applications. The vulnerability operates by allowing attackers to inject malicious JavaScript code or HTML content that gets executed when legitimate users view affected pages. When users navigate to pages containing the malicious content, their browsers execute the injected scripts, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The onerror attribute variant specifically exploits how browsers handle failed image loading events, while the glow tag represents another vector where improperly sanitized user input gets rendered as executable code. This multi-vector approach increases the attack surface and makes detection and mitigation more challenging for system administrators.
The operational impact of CVE-2002-1829 extends beyond simple script execution to potentially compromise entire user sessions and data integrity within the OpenBB environment. Attackers can leverage this vulnerability to steal cookies, modify user permissions, or redirect victims to phishing sites that appear legitimate. The persistent nature of the vulnerability means that once injected, malicious code can affect multiple users over time without requiring repeated exploitation attempts. This makes the vulnerability particularly dangerous for bulletin board systems where users regularly interact with content posted by others. The attack vectors described in the CVE specifically target the core functionality of the bulletin board system, making it difficult for administrators to isolate and patch the issue without comprehensive application review.
Mitigation strategies for this vulnerability should include comprehensive input validation and output encoding across all user-supplied content processing pathways. Implementing proper sanitization of HTML content before rendering ensures that potentially dangerous attributes like onerror and custom tags such as glow are neutralized or removed. The solution must address the root cause by ensuring that all user input passes through strict validation mechanisms that conform to secure coding practices outlined in OWASP Top Ten and NIST guidelines. System administrators should implement content security policies and regularly audit application code for similar vulnerabilities. Additionally, upgrading to patched versions of OpenBB or implementing web application firewalls that can detect and block XSS payloads represents essential defensive measures that align with ATT&CK framework techniques for defending against web-based attacks. The vulnerability demonstrates the critical importance of proper input handling in web applications and serves as a reminder of the persistent nature of XSS threats in legacy systems.
