CVE-2014-0620 in TC7200
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Technicolor (formerly Thomson) TC7200 STD6.01.12 allow remote attackers to inject arbitrary web script or HTML via the (1) ADDNewDomain parameter to parental/website-filters.asp or (2) VmTracerouteHost parameter to goform/status/diagnostics-route.

The CVE-2014-0620 vulnerability represents a critical cross-site scripting weakness affecting Technicolor TC7200 routers running firmware version STD6.01.12. This vulnerability resides in the web-based administrative interface of the device, specifically within two distinct parameters that handle user input without proper sanitization or validation. The flaw demonstrates the classic characteristics of XSS vulnerabilities, where malicious actors can inject arbitrary script code that executes in the context of authenticated users' browsers. The vulnerability affects both the parental control functionality and network diagnostics features, creating multiple attack vectors that could be exploited by remote adversaries.
The technical implementation of this vulnerability stems from improper input validation within the router's web interface. When the ADDNewDomain parameter in parental/website-filters.asp receives user-supplied data, or when the VmTracerouteHost parameter in goform/status/diagnostics-route processes input, the system fails to properly escape or sanitize these values before incorporating them into dynamically generated web responses. This lack of input sanitization creates an environment where attackers can inject malicious JavaScript code that gets executed when other users view the affected web pages. The vulnerability is classified under CWE-79 as a failure to sanitize user input, which is a fundamental weakness in web application security design. The attack surface is particularly concerning because it affects administrative functions that are typically accessed by users with elevated privileges, potentially allowing attackers to escalate their access and compromise the entire network.
The operational impact of this vulnerability extends beyond simple script injection, as it could enable attackers to perform session hijacking, steal administrative credentials, or redirect users to malicious sites. The presence of XSS vulnerabilities in network infrastructure devices like routers poses significant risks to enterprise and home network security, as these devices often serve as gateways to internal systems. Attackers could leverage this vulnerability to gain unauthorized access to the router's administrative interface, potentially modifying firewall rules, changing network configurations, or installing persistent backdoors. The attack could also be used for credential theft, where users' authentication tokens are captured when they interact with compromised pages, leading to complete network compromise. According to ATT&CK framework, this vulnerability maps to T1059.007 for Scripting and T1566.001 for Spearphishing Attachment, as it enables attackers to deliver malicious payloads through web-based attack vectors.
Mitigation strategies for this vulnerability should focus on immediate firmware updates from Technicolor, as the manufacturer would have released patches to address the input sanitization issues. Network administrators should implement strict input validation on all web applications and ensure that user-supplied data is properly escaped before being rendered in web pages. The implementation of Content Security Policy headers can provide additional protection against XSS attacks by restricting the sources from which scripts can be loaded. Regular security assessments of network infrastructure devices should include web application vulnerability scanning to identify similar issues. The vulnerability highlights the importance of secure coding practices and input validation in embedded systems, particularly those with web interfaces that are accessible from untrusted networks. Organizations should also consider network segmentation and access controls to limit the potential impact of such vulnerabilities, ensuring that even if one device is compromised, the attacker cannot easily move laterally within the network infrastructure.
