Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in cgi-bin/ddns in the web management panel for the WBR3404TX broadband router with firmware R1.94p0vTIG allow remote attackers to inject arbitrary web script or HTML via the (1) DD or (2) DU parameter.

The vulnerability identified as CVE-2007-5027 represents a critical cross-site scripting flaw discovered in the web management interface of the WBR3404TX broadband router running firmware version R1.94p0vTIG. This vulnerability resides within the cgi-bin/ddns component of the router's web server implementation, specifically targeting parameters named DD and DU. The flaw enables remote attackers to execute malicious scripts in the context of authenticated users who access the router's web management panel, creating a significant security risk for network administrators and end users who rely on the device for internet connectivity.
The technical nature of this vulnerability stems from inadequate input validation and output sanitization within the router's web interface. When the DD or DU parameters are processed by the cgi-bin/ddns script, the system fails to properly sanitize user-supplied data before incorporating it into dynamic web responses. This improper handling allows attackers to inject malicious HTML content or JavaScript code through these parameters, which then executes in the browser of any user who views the affected page. The vulnerability is classified as a classic reflected cross-site scripting issue under CWE-79, where malicious input is immediately reflected back to the user without proper encoding or validation.
The operational impact of this vulnerability extends beyond simple script injection, as it provides attackers with the capability to perform various malicious activities within the network environment. An attacker could potentially steal session cookies, redirect users to malicious websites, deface the router's web interface, or even execute arbitrary commands if the router's management interface allows for further exploitation. The vulnerability is particularly dangerous because it affects the router's web management panel, which typically requires administrative privileges to access, making it a prime target for attackers seeking to gain persistent access to network infrastructure. This aligns with ATT&CK technique T1059.007 for Command and Scripting Interpreter, as the vulnerability enables remote code execution through script injection.
The exploitation of this vulnerability requires minimal technical expertise, as attackers only need to craft malicious URLs containing the vulnerable parameters and convince victims to click on them while authenticated to the router's management interface. This makes the attack vector particularly effective in social engineering scenarios where users might be tricked into visiting malicious links. Network administrators who regularly access their router's management interface from web browsers are at risk, especially when using the same browser session across multiple applications. The vulnerability also demonstrates the importance of input validation at all levels of web application development, as the flaw exists in the router's embedded web server implementation rather than in client-side code. Security professionals should note that this vulnerability underscores the critical need for proper security testing of embedded network devices and highlights the potential for widespread impact when such flaws exist in commonly deployed networking equipment. Organizations should implement immediate mitigations including firmware updates, network segmentation, and monitoring for suspicious traffic patterns that might indicate exploitation attempts.
