CVE-2006-0254 in Geronimo
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Apache Geronimo 1.0 allow remote attackers to inject arbitrary web script or HTML via the (1) time parameter to cal2.jsp and (2) any invalid parameter, which causes an XSS when the log file is viewed by the Web-Access-Log viewer.

Apache Geronimo version 1.0 contains multiple cross-site scripting vulnerabilities that represent significant security weaknesses in the web application framework. These vulnerabilities stem from inadequate input validation and sanitization mechanisms within the application's logging and parameter handling components. The specific flaws occur in the cal2.jsp file where the time parameter is not properly validated, and in the broader parameter handling system where invalid parameters are processed without adequate security measures. The vulnerability classification aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and represents a critical risk to web application security.
The technical implementation of these vulnerabilities allows remote attackers to execute malicious scripts within the context of other users' browsers through the manipulation of web parameters. When the time parameter is passed to cal2.jsp, the application fails to sanitize the input before processing, creating an opportunity for attackers to inject malicious JavaScript code or HTML content. Similarly, when invalid parameters are encountered by the application, the error handling mechanism does not properly escape or validate these inputs before they are displayed in the Web-Access-Log viewer. This creates a scenario where attackers can craft malicious payloads that persist in log files and execute when legitimate users view the access logs, making this a persistent and insidious vulnerability.
The operational impact of these vulnerabilities extends beyond simple script injection, as they can be leveraged to perform session hijacking, deface web applications, steal sensitive user data, or redirect users to malicious sites. The Web-Access-Log viewer component serves as a critical attack vector because it provides administrative access to log information that is typically considered safe and non-executable. When attackers can inject code into log files that are subsequently viewed by administrators, they gain the ability to execute arbitrary code in the context of privileged users, potentially leading to complete system compromise. This vulnerability type is particularly concerning because it operates through legitimate application logging mechanisms, making it difficult to detect and prevent through standard security monitoring approaches.
The remediation of these vulnerabilities requires comprehensive input validation and output encoding across all parameter handling and logging components. Organizations should implement strict parameter validation for all inputs, including the time parameter in cal2.jsp, and ensure that all user-supplied data is properly escaped before being processed or displayed in log files. The implementation of Content Security Policy headers and proper HTML encoding mechanisms should be enforced throughout the application to prevent script execution in log viewer components. Additionally, regular security assessments and input validation testing should be conducted to identify similar vulnerabilities in other application components, as this class of vulnerability often appears in web applications that do not follow secure coding practices. These fixes align with ATT&CK technique T1566, which covers the exploitation of web application vulnerabilities for initial access or privilege escalation, and emphasize the importance of proper input validation as a fundamental security control.
