CVE-2010-4364 in DaDaBIK
Summary
by MITRE
DaDaBIK 4.3 beta3, when running in a case-sensitive environment, does not include the htmLawed library, which allows remote attackers to bypass the protection mechanism for CVE-2010-4355 and conduct cross-site scripting (XSS) attacks via the (1) html content and (2) rich_editor fields. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2010-4364 affects DaDaBIK version 4.3 beta3 and represents a critical security flaw that undermines the application's input validation mechanisms. This issue specifically manifests when the application operates within a case-sensitive file system environment, creating a scenario where essential security components fail to load properly. The vulnerability directly relates to the improper handling of HTML content processing, which creates a pathway for malicious actors to circumvent existing security controls designed to prevent cross-site scripting attacks.
The technical flaw stems from the application's failure to properly include the htmLawed library, a critical component responsible for sanitizing HTML content and preventing XSS vulnerabilities. When the application runs in a case-sensitive environment, the library's inclusion mechanism fails, resulting in the bypass of protective measures that were specifically implemented to address CVE-2010-4355. This creates a dangerous condition where user-provided content in the html content and rich_editor fields can contain malicious scripts that execute in the context of other users' browsers. The vulnerability operates through a classic bypass attack pattern where the absence of proper input sanitization allows attackers to inject harmful code that can persist and execute across different user sessions.
The operational impact of this vulnerability is severe and multifaceted, as it enables remote attackers to conduct persistent cross-site scripting attacks against users of the application. Attackers can exploit this weakness to inject malicious JavaScript code into the html content and rich_editor fields, potentially leading to session hijacking, data theft, privilege escalation, and other malicious activities. The vulnerability's exploitation does not require authentication, making it particularly dangerous as it can be leveraged by anyone who can submit content through the affected fields. This creates a significant risk for web applications that rely on user-generated content and can result in widespread compromise of user data and application integrity.
The security implications extend beyond simple XSS execution, as this vulnerability demonstrates poor defensive programming practices and inadequate error handling in the application's security architecture. The issue aligns with CWE-20, "Improper Input Validation," and CWE-79, "Cross-site Scripting," while also reflecting ATT&CK techniques related to command and control through web-based attacks. Organizations using DaDaBIK 4.3 beta3 should immediately implement mitigations including ensuring proper library inclusion regardless of file system case sensitivity, implementing additional input validation layers, and deploying web application firewalls to detect and block malicious payloads. The recommended approach involves upgrading to patched versions of the application, implementing comprehensive input sanitization, and establishing monitoring for suspicious content submissions in the affected fields.
This vulnerability highlights the importance of robust dependency management and the critical need for applications to maintain consistent security controls regardless of deployment environment characteristics. The case-sensitive environment requirement exposes a design flaw where security controls are conditional rather than absolute, creating potential attack vectors that can be exploited by adversaries. The remediation process should include thorough testing of security controls across different deployment scenarios and implementation of defensive measures that do not rely on specific environmental conditions for proper functionality. Organizations should also consider implementing automated security testing that validates the proper inclusion and operation of security libraries under various system configurations to prevent similar vulnerabilities from manifesting in production environments.
