CVE-2008-1260 in P-2602HW-D1A
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities on the Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware allow remote attackers to (1) make the admin web server available on the Internet (WAN) interface via the WWWAccessInterface parameter to Forms/RemMagWWW_1 or (2) change the IP whitelisting timeout via the StdioTimout parameter to Forms/rpSysAdmin_1.

The CVE-2008-1260 vulnerability represents a critical cross-site request forgery issue affecting the Zyxel P-2602HW-D1A router running firmware version 3.40(AJZ.1). This vulnerability falls under the CWE-352 category, which specifically addresses cross-site request forgery conditions where attackers can trick authenticated users into performing unintended actions. The flaw exists within the router's web-based administration interface, making it particularly dangerous as it allows remote exploitation without requiring authentication credentials. The vulnerability manifests through two distinct attack vectors that directly compromise the router's security posture and network access controls.
The technical implementation of this vulnerability exploits the absence of proper anti-CSRF protections in the affected web forms. Attackers can manipulate the WWWAccessInterface parameter within the Forms/RemMagWWW_1 endpoint to remotely enable internet access to the administrative web server through the WAN interface. This configuration change effectively exposes the router's management interface to external networks, bypassing the intended security boundaries. Additionally, the StdioTimout parameter in the Forms/rpSysAdmin_1 endpoint can be modified to alter the IP whitelisting timeout, which disrupts the router's access control mechanisms and potentially allows unauthorized access attempts from previously blocked IP addresses.
The operational impact of this vulnerability is severe as it fundamentally undermines the router's security architecture. When attackers successfully exploit the first vector, they can make the administrative interface accessible from the internet, creating an attack surface that allows for further exploitation including potential credential theft, configuration changes, or complete router compromise. The second vulnerability allows attackers to manipulate access timing controls, which could be used in conjunction with other attacks to bypass time-based access restrictions. These vulnerabilities align with ATT&CK technique T1071.004 for application layer protocol manipulation and T1566 for credential access through web application attacks.
Mitigation strategies should focus on immediate network segmentation and access control enforcement. Organizations should disable remote administrative access to network devices whenever possible and implement strict firewall rules to restrict access to management interfaces. The affected firmware version should be updated to the latest available version from Zyxel, as this vulnerability was likely addressed in subsequent releases. Network administrators should also implement monitoring solutions to detect unauthorized configuration changes to administrative interfaces. Additionally, implementing proper CSRF tokens and validation mechanisms within web applications can prevent similar vulnerabilities from occurring in the future. The vulnerability demonstrates the importance of secure web application development practices and proper input validation as outlined in OWASP Top Ten categories and NIST cybersecurity frameworks for network device security management.
