CVE-2002-1640 in Configurator
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Oracle Configurator before 11.5.7.17.32 and 11.5.6.16.53 allows remote attackers to inject arbitrary web script or HTML via (1) Text Features in the DHTML UI or (2) the test parameter to the oracle.apps.cz.servlet.UiServlet servlet.

The vulnerability described in CVE-2002-1640 represents a critical cross-site scripting flaw affecting Oracle Configurator versions prior to 11.5.7.17.32 and 11.5.6.16.53. This vulnerability exposes the application to remote code execution risks through malicious script injection attacks that can compromise user sessions and data integrity. The flaw exists within the application's handling of user input in two distinct attack vectors, making it particularly dangerous as it provides multiple pathways for exploitation.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding mechanisms within Oracle Configurator's web interface. When users interact with Text Features in the DHTML UI or when the test parameter is passed to the oracle.apps.cz.servlet.UiServlet servlet, the application fails to properly sanitize or escape user-supplied data before rendering it in web pages. This insufficient sanitization creates opportunities for attackers to inject malicious JavaScript code or HTML content that executes in the context of other users' browsers. The vulnerability specifically aligns with CWE-79, which categorizes cross-site scripting flaws as weaknesses in input validation and output encoding.
The operational impact of CVE-2002-1640 extends beyond simple data theft or defacement, as it enables attackers to perform session hijacking, steal sensitive information, and potentially escalate privileges within the Oracle environment. Attackers can craft malicious payloads that exploit the DHTML UI text features to execute scripts in victim browsers, while the test parameter vulnerability in UiServlet allows for broader exploitation across different application components. These vulnerabilities can be leveraged to establish persistent access points, manipulate application behavior, and compromise the confidentiality and integrity of Oracle Configurator deployments.
Mitigation strategies for this vulnerability should focus on immediate patch application to versions 11.5.7.17.32 and 11.5.6.16.53 which contain the necessary security fixes. Organizations should implement comprehensive input validation measures at all entry points, including the DHTML UI components and servlet parameters, to prevent malicious code injection. Additionally, implementing proper output encoding and content security policies can provide defense-in-depth measures against similar vulnerabilities. The ATT&CK framework categorizes this type of vulnerability under T1566, specifically targeting the execution of malicious code through web application vulnerabilities, making it a critical target for security hardening initiatives and vulnerability management programs.
