CVE-2010-4172 in Tomcat
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in the Manager application in Apache Tomcat 6.0.12 through 6.0.29 and 7.0.0 through 7.0.4 allow remote attackers to inject arbitrary web script or HTML via the (1) orderBy or (2) sort parameter to sessionsList.jsp, or unspecified input to (3) sessionDetail.jsp or (4) java/org/apache/catalina/manager/JspHelper.java, related to use of untrusted web applications.

The vulnerability identified as CVE-2010-4172 represents a critical cross-site scripting weakness affecting Apache Tomcat versions ranging from 6.0.12 through 6.0.29 and 7.0.0 through 7.0.4. This flaw exists within the Manager application component of the web server, which provides administrative functionality for managing deployed web applications. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into web responses. The attack surface encompasses multiple entry points including the sessionsList.jsp page where orderBy and sort parameters are processed, as well as sessionDetail.jsp and JspHelper.java components that handle unspecified input from untrusted web applications. These vulnerabilities fall under CWE-79 which specifically addresses cross-site scripting flaws in web applications, where improper validation of user input allows malicious scripts to be executed in the context of other users' browsers. The implications extend beyond simple data theft as these vulnerabilities enable attackers to manipulate the application's behavior and potentially escalate privileges within the web server environment.
The technical exploitation of this vulnerability occurs through the manipulation of HTTP parameters that are directly processed by the Tomcat Manager application. When attackers submit malicious payloads through the orderBy or sort parameters in sessionsList.jsp, the application fails to properly sanitize these inputs before rendering them in the web response. Similarly, the sessionDetail.jsp and JspHelper.java components process user input without adequate validation, creating additional attack vectors where malicious scripts can be injected into the application's output. The vulnerability is particularly concerning because it affects the manager application itself, which typically operates with elevated privileges and can execute administrative functions on the web server. This creates a potential pathway for attackers to gain unauthorized access to the server's management interface, potentially leading to complete server compromise. The attack requires no authentication for the initial exploitation phase, as the vulnerability exists in the application's response handling rather than in authentication mechanisms, making it particularly dangerous in environments where the manager application is accessible to untrusted users.
The operational impact of CVE-2010-4172 extends beyond immediate script execution capabilities to encompass broader security implications for web server environments. Attackers can leverage these vulnerabilities to execute arbitrary code in the context of the web server process, potentially leading to complete system compromise. The vulnerability enables malicious actors to perform session hijacking, data exfiltration, and modification of web application content, which can result in significant financial and reputational damage. Organizations running affected Tomcat versions face potential exposure to persistent threats where attackers can maintain access through injected scripts that survive server restarts. The vulnerability also affects the integrity of the web application's administrative interface, potentially allowing attackers to modify deployed applications, create new applications, or even delete existing ones. From an ATT&CK framework perspective, this vulnerability maps to T1059 (Command and Scripting Interpreter) and T1566 (Phishing) as attackers can use the XSS capabilities to execute malicious commands and establish persistence. The vulnerability affects the confidentiality, integrity, and availability of web applications, representing a fundamental breach in the web server's security posture.
Mitigation strategies for CVE-2010-4172 must address both immediate remediation and long-term security improvements. The most effective immediate solution involves upgrading to Apache Tomcat versions 6.0.30 or 7.0.5, which contain the necessary patches to address the XSS vulnerabilities. Organizations should also implement input validation and output encoding mechanisms throughout their web applications to prevent similar issues from occurring in other components. The manager application should be restricted to trusted users only, with access controls implemented at the network level to prevent unauthorized access to administrative interfaces. Security headers such as Content Security Policy should be implemented to limit the execution of unauthorized scripts in the browser context. Organizations should also consider implementing web application firewalls and regular security scanning to detect similar vulnerabilities in other applications. Additionally, security teams should conduct comprehensive code reviews focusing on input validation and output encoding practices, particularly in areas where user-supplied data is processed. The vulnerability highlights the importance of maintaining up-to-date software components and implementing proper security controls in administrative interfaces, as these components often represent the most attractive targets for attackers seeking to compromise entire web server environments.
