CVE-2010-2433 in WebSphere ILOG JRules
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in content/internalError.jsp in IBM WebSphere ILOG JRules 6.7 allow remote attackers to inject arbitrary web script or HTML via an RTS URL to (1) explore/explore.jsp, (2) compose/compose.jsp, or (3) home.jsp in faces/.

The vulnerability identified as CVE-2010-2433 represents a critical cross-site scripting flaw within IBM WebSphere ILOG JRules 6.7, specifically affecting the content/internalError.jsp component. This vulnerability stems from insufficient input validation and output encoding mechanisms that fail to properly sanitize user-supplied data before rendering it within web pages. The affected application components include explore/explore.jsp, compose/compose.jsp, and home.jsp in the faces/ directory, all of which process RTS URLs that can be manipulated by remote attackers to execute malicious scripts.
The technical implementation of this vulnerability occurs when the application fails to adequately filter or escape special characters in URL parameters, particularly those related to RTS (Rule Task Service) URLs. Attackers can craft malicious URLs containing script code that gets executed in the context of authenticated users' browsers when they navigate to the affected pages. This flaw operates under CWE-79 which specifically addresses Cross-Site Scripting vulnerabilities, where improper neutralization of input during web page generation creates opportunities for malicious code injection. The vulnerability is classified as a reflective XSS attack since the malicious script is reflected back to the user through the application's response without being stored on the server.
The operational impact of this vulnerability is significant as it enables attackers to perform various malicious activities including session hijacking, credential theft, and data exfiltration. An attacker could exploit this vulnerability to steal user sessions, redirect victims to malicious websites, or inject malware through the compromised browser. The attack vector is particularly dangerous because it requires no privileged access or authentication, making it easily exploitable by remote threat actors. The vulnerability affects the entire IBM WebSphere ILOG JRules 6.7 platform and could potentially compromise sensitive business rule data and operational integrity. According to ATT&CK framework, this vulnerability maps to T1566.001 (Phishing: Spearphishing Attachment) and T1059.007 (Command and Scripting Interpreter: JavaScript) as attackers could leverage the XSS to deliver malicious payloads and establish persistent access.
Mitigation strategies for CVE-2010-2433 should include immediate application patching from IBM to address the root cause of the input validation failures. Organizations should implement comprehensive input sanitization mechanisms that properly encode all user-supplied data before rendering it in web contexts. The implementation of Content Security Policy (CSP) headers can provide additional protection against script execution, while proper output encoding techniques such as HTML entity encoding should be enforced throughout the application. Security headers including X-Content-Type-Options and X-Frame-Options should be configured to prevent content sniffing and clickjacking attacks. Regular security testing including dynamic application security testing (DAST) and manual penetration testing should be conducted to identify similar vulnerabilities in the application codebase. Organizations should also consider implementing web application firewalls (WAF) with rules specifically designed to detect and block XSS attack patterns, and maintain updated threat intelligence feeds to monitor for exploitation attempts targeting this vulnerability. The patching process should be prioritized immediately as the vulnerability exists in the application's core functionality and poses a direct threat to application security and data integrity.
