CVE-2010-4841 in EventLog Analyzer
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in ManageEngine EventLog Analyzer 6.1 allow remote attackers to inject arbitrary web script or HTML via the (1) HOST_ID, (2) OS, (3) GROUP, (4) exportFile, (5) load, (6) type, or (7) tab parameter to INDEX.do, the (8) reported parameter to INDEX2.do, the (9) gId parameter to hostlist.do, the (10) newWindow parameter to globalSettings.do, or the (11) STATUS parameter to enableHost.do.

The CVE-2010-4841 vulnerability represents a critical cross-site scripting flaw in ManageEngine EventLog Analyzer version 6.1, a network security monitoring and log management solution. This vulnerability stems from inadequate input validation and sanitization mechanisms within the web application's parameter handling processes, creating multiple entry points for malicious actors to inject arbitrary web scripts or HTML content. The vulnerability affects several key endpoints including INDEX.do, INDEX2.do, hostlist.do, globalSettings.do, and enableHost.do, each representing different functional areas of the application's web interface. The flaw demonstrates a classic weakness in web application security where user-supplied data is directly incorporated into web responses without proper sanitization or encoding, making it susceptible to exploitation by remote attackers who can manipulate various parameters to execute malicious code in the context of authenticated users' browsers.
The technical exploitation of this vulnerability occurs through parameter manipulation attacks targeting specific input fields within the application's HTTP request handling mechanisms. Attackers can inject malicious scripts through parameters such as HOST_ID, OS, GROUP, exportFile, load, type, tab, reported, gId, newWindow, and STATUS, each representing different data flow paths within the application's architecture. The vulnerability's impact is amplified by the fact that these parameters are processed in different contexts, including user interface elements, configuration settings, and reporting functions, providing attackers with multiple potential attack vectors. When these malicious inputs are processed and rendered without proper HTML encoding or validation, they can execute within the victim's browser session, potentially leading to session hijacking, credential theft, or redirection to malicious sites. This vulnerability directly maps to CWE-79 which defines cross-site scripting as a weakness where applications fail to properly validate or encode user-supplied input before incorporating it into dynamically generated web content.
The operational impact of CVE-2010-4841 extends beyond simple script execution to encompass significant security risks for organizations relying on ManageEngine EventLog Analyzer for network security monitoring. Since the application likely serves as a central point for log analysis and security event management, successful exploitation could allow attackers to compromise the integrity of security monitoring processes, potentially masking malicious activities or manipulating security alerts. The vulnerability's scope across multiple parameters suggests a systemic weakness in input validation rather than isolated flaws, indicating that the application's security architecture may be insufficiently hardened against common web application attacks. Organizations using this version of EventLog Analyzer face risks including unauthorized access to security logs, potential data exfiltration, and the ability for attackers to modify system configurations through the globalSettings.do endpoint. The vulnerability also aligns with ATT&CK technique T1059.007 which covers command and scripting interpreter for executing malicious scripts in user contexts, potentially enabling attackers to establish persistent access or escalate privileges within the monitored network environment.
Mitigation strategies for this vulnerability should prioritize immediate patching of the ManageEngine EventLog Analyzer to version 6.2 or later, as this represents the most effective solution to address the underlying input validation flaws. Organizations should implement comprehensive input sanitization measures across all web application interfaces, ensuring that all user-supplied parameters undergo proper validation and encoding before being processed or displayed in web responses. Network segmentation and access controls should be strengthened to limit exposure of the vulnerable application to untrusted networks, while regular security assessments should be conducted to identify similar vulnerabilities in other web applications within the organization's infrastructure. The implementation of Content Security Policy headers and proper HTTP response headers can provide additional layers of protection against XSS exploitation attempts, though these measures serve as defensive mechanisms rather than primary fixes for the core vulnerability. Security teams should also establish monitoring procedures to detect unusual parameter patterns in application logs that might indicate attempted exploitation of similar vulnerabilities.
