CVE-2007-3593 in Netflow Analyzer
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in ManageEngine NetFlow Analyzer 5 allow remote attackers to inject arbitrary web script or HTML via the (1) alpha parameter in (a) netflow/jspui/applicationList.jsp, the (2) task parameter in (b) netflow/jspui/appConfig.jsp, the (3) view parameter in (c) netflow/jspui/index.jsp, and the (4) rtype parameter in (d) netflow/jspui/selectDevice.jsp and (e) netflow/jspui/customReport.jsp. NOTE: it was later reported that vector 3 also affects 7.5 build 7500.

The vulnerability identified as CVE-2007-3593 represents a critical cross-site scripting flaw in ManageEngine NetFlow Analyzer version 5, which falls under the CWE-79 category of Cross-Site Scripting. This vulnerability stems from insufficient input validation and sanitization within multiple web application parameters, creating multiple attack vectors that allow remote threat actors to inject malicious scripts into web pages viewed by other users. The flaw specifically affects the application's user interface components that process user-supplied data without proper sanitization, enabling attackers to execute arbitrary code within the context of victims' browsers.
The technical exploitation of this vulnerability occurs through four distinct parameter injection points within the application's web interface. The first vector involves the alpha parameter in the applicationList.jsp file, while the second targets the task parameter within appConfig.jsp. The third vector affects the view parameter in index.jsp, and the fourth and fifth vectors utilize the rtype parameter in both selectDevice.jsp and customReport.jsp. These parameters are processed by the web application without adequate input validation, allowing attackers to embed malicious JavaScript code that executes when other users navigate to affected pages. The vulnerability affects not only version 5 but also 7.5 build 7500 as subsequently reported, indicating the persistence of this input sanitization flaw across multiple releases.
The operational impact of this vulnerability is severe as it enables attackers to perform session hijacking, steal user credentials, redirect victims to malicious websites, or execute arbitrary commands on affected systems. Since NetFlow Analyzer is typically used for network monitoring and analysis, attackers could potentially gain access to sensitive network traffic data and system information. The remote nature of the attack means that threat actors can exploit this vulnerability from anywhere on the internet without requiring local system access, making it particularly dangerous for organizations that expose this application to external networks. The vulnerability could also be leveraged as a stepping stone for further attacks within the network infrastructure.
Organizations should implement immediate mitigations including input validation and output encoding for all user-supplied parameters, regular security updates, and network segmentation to limit access to vulnerable applications. The ATT&CK framework categorizes this vulnerability under T1566 - Phishing and T1059 - Command and Scripting Interpreter, highlighting the potential for attackers to use this vulnerability for initial access and execution. Additionally, implementing proper web application firewalls and security headers can provide additional defense-in-depth measures. Regular security assessments and vulnerability scanning should be conducted to identify similar input validation flaws in other applications, as this represents a common weakness in web applications that requires comprehensive remediation across all user input handling mechanisms.
