CVE-2006-2349 in E-Business Designer
Summary
by MITRE
E-Business Designer (eBD) 3.1.4 and earlier allows remote attackers to upload or modify arbitrary files, and execute arbitrary code, via a direct request to (1) common/html_editor/image_browser.upload.html, (2) common/html_editor/image_browser.html, or (3) common/html_editor/html_editor.html. NOTE: this can also be used for cross-site scripting (XSS) attacks by uploading cascading style sheet (.CSS) files.

The vulnerability identified as CVE-2006-2349 represents a critical file upload flaw in Oracle E-Business Designer version 3.1.4 and earlier systems. This weakness stems from insufficient input validation and access control mechanisms within the web application's file handling components. The vulnerability specifically affects three key endpoints: common/html_editor/image_browser.upload.html, common/html_editor/image_browser.html, and common/html_editor/html_editor.html, which collectively form part of the HTML editor functionality used for content management within the e-business platform.
The technical exploitation of this vulnerability occurs through direct HTTP requests to the vulnerable endpoints, allowing remote attackers to bypass authentication and authorization controls. When an attacker successfully uploads a file through these interfaces, the system fails to properly validate file types, extensions, or content, enabling the upload of malicious executables or script files. This flaw directly maps to CWE-434, which describes "Unrestricted Upload of File with Dangerous Type," a common vulnerability pattern that occurs when applications allow file uploads without proper validation of file contents or types. The vulnerability also creates opportunities for cross-site scripting attacks when CSS files are uploaded, as these can be executed in the context of other users' browsers, representing a secondary exploitation vector.
The operational impact of this vulnerability is severe and multifaceted, potentially enabling complete system compromise. Remote attackers can execute arbitrary code on the target system with the privileges of the web application, which typically runs with elevated permissions. This capability allows for privilege escalation, data exfiltration, system reconnaissance, and the establishment of persistent backdoors. The vulnerability affects the integrity and confidentiality of business data, as attackers can modify existing files or create new malicious content that persists across system operations. Additionally, the XSS capability through CSS file uploads can be leveraged to steal session cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users, undermining the application's security model.
From a threat modeling perspective, this vulnerability aligns with several ATT&CK techniques including T1190 for exploitation of vulnerabilities, T1059 for command and scripting interpreter usage, and T1566 for credential access through social engineering. Organizations should implement immediate mitigations including restricting file upload capabilities, implementing strict file type validation, and employing web application firewalls to filter suspicious requests. The recommended remediation strategy involves patching to the latest version of Oracle E-Business Designer, implementing proper input validation controls, and conducting thorough security testing of file handling components. Additionally, network segmentation and monitoring of file upload activities can help detect and prevent exploitation attempts, while regular security assessments should verify that no similar vulnerabilities exist in related components or third-party libraries used within the e-business environment.
