CVE-2007-6730 in P-330W router
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in the web management interface in the ZyXEL P-330W router allow remote attackers to hijack the authentication of administrators for requests that (1) enable remote router management via goform/formRmtMgt or (2) modify the administrator password via goform/formPasswordSetup.

The CVE-2007-6730 vulnerability represents a critical cross-site request forgery flaw in ZyXEL P-330W router's web management interface, demonstrating a fundamental weakness in session management and authentication mechanisms. This vulnerability falls under the CWE-352 category, which specifically addresses Cross-Site Request Forgery vulnerabilities, where attackers can trick authenticated users into performing unintended actions without their knowledge or consent. The flaw exists in the router's web interface implementation, where proper CSRF protection mechanisms are absent or insufficient, allowing malicious actors to exploit the authentication state of administrators through crafted web requests.
The technical exploitation of this vulnerability occurs through specifically crafted HTTP requests that target two distinct administrative functions within the router's management interface. The first attack vector enables remote router management via the goform/formRmtMgt endpoint, which allows attackers to remotely configure and control router settings without administrator knowledge. The second vector targets the goform/formPasswordSetup endpoint, enabling password modification attacks that can completely compromise administrative access to the device. These endpoints lack proper anti-CSRF token validation, making them susceptible to exploitation through social engineering or malicious websites that automatically submit requests to the router's management interface.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with complete administrative control over the affected router. Once exploited, attackers can modify network configurations, enable remote access, change administrator credentials, and potentially establish persistent backdoors within the network infrastructure. This represents a significant threat to network security, as routers serve as critical gateways and often contain sensitive configuration data that can be leveraged for further attacks. The vulnerability affects the router's core management functionality, making it particularly dangerous as it allows attackers to compromise the device's fundamental security posture and potentially use it as a pivot point for attacking other network devices.
Organizations and network administrators should immediately implement mitigations including disabling remote management features when not required, implementing strong authentication mechanisms, and ensuring that all network devices receive regular firmware updates. The vulnerability highlights the importance of proper input validation and anti-CSRF protection in web applications, particularly those managing critical network infrastructure. Security practitioners should consider implementing network segmentation and monitoring for unauthorized configuration changes, as well as conducting regular security assessments of network devices to identify similar vulnerabilities. The ATT&CK framework categorizes this type of vulnerability under T1071.004 Application Layer Protocol: DNS, where attackers may leverage compromised routers for data exfiltration or command and control communications, making the mitigation of such vulnerabilities essential for maintaining overall network security posture.
