CVE-2006-2347 in E-Business Designer
Summary
by MITRE
E-Business Designer (eBD) 3.1.4 and earlier allows remote attackers to obtain the full path of the web server via " " characters, and possibly other invalid values, in (1) the id parameter to form_grupo.html, or requests to the (2) archivos/ and (3) files/ directories. NOTE: this issue might be resultant from SQL injection.

The vulnerability described in CVE-2006-2347 affects Oracle E-Business Designer version 3.1.4 and earlier, presenting a significant information disclosure risk that could enable remote attackers to obtain sensitive server path information. This flaw manifests through improper input validation mechanisms within the web application's parameter handling, specifically targeting the form_grupo.html script and directory access points. The vulnerability operates by accepting specially crafted input containing space characters and other invalid values that trigger the application to reveal complete server path details in error responses or direct output.
The technical exploitation occurs through manipulation of the id parameter in the form_grupo.html endpoint, as well as through requests directed to the archivos/ and files/ directories within the application's web root. When these parameters contain invalid input such as space characters or other malformed data, the application fails to properly sanitize or validate the input before processing, leading to the exposure of filesystem paths. This behavior indicates a lack of proper input validation and error handling mechanisms, allowing attackers to infer the underlying server structure and potentially identify additional attack vectors.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical path information that could facilitate more sophisticated attacks. The exposure of full server paths enables adversaries to better understand the application's directory structure, potentially revealing sensitive file locations, configuration details, and underlying system architecture. This information could be leveraged to craft more targeted attacks or to identify additional vulnerabilities within the application's file access mechanisms. The vulnerability's classification as potentially stemming from SQL injection suggests that the underlying issue may involve improper handling of user input that could also lead to database access or manipulation.
This vulnerability aligns with CWE-200, which specifically addresses the exposure of sensitive information to an unauthorized actor, and represents a classic example of information disclosure through improper error handling. The attack pattern corresponds to techniques documented in the ATT&CK framework under reconnaissance phases, where adversaries gather information about target systems to inform subsequent exploitation attempts. The issue demonstrates a fundamental flaw in input validation and sanitization processes that should be addressed through proper parameter validation, error handling, and secure coding practices. Organizations affected by this vulnerability should implement immediate mitigations including input sanitization, proper error handling, and access controls to prevent unauthorized path disclosure.
The remediation approach should focus on implementing comprehensive input validation mechanisms that reject or sanitize invalid characters before processing user-supplied data. This includes establishing proper parameter validation for all input points, particularly those handling file paths or directory requests. Additionally, error handling should be reviewed to ensure that internal system information is not exposed to end users through error messages or response content. The implementation of proper access controls and directory traversal prevention measures would further mitigate the risk of path disclosure and related security issues. Organizations should also consider implementing web application firewalls or intrusion detection systems to monitor for suspicious parameter patterns that could indicate attempted exploitation of this vulnerability.
