Summary
by MITRE
Cross-site request forgery (CSRF) vulnerability in webconfig/admin_passwd/passwd.html/admin_passwd in Xavi X7968 allows remote attackers to hijack the authentication of administrators for requests that change the administrator password via the sysUserName, sysPassword, and sysCfmPwd parameters.

The CVE-2012-5323 vulnerability represents a critical cross-site request forgery flaw in the Xavi X7968 device management interface. This vulnerability exists within the webconfig/admin_passwd/passwd.html/admin_passwd component of the device's web administration portal, specifically targeting the password change functionality. The flaw allows remote attackers to execute unauthorized administrative actions by tricking administrators into visiting malicious web pages that automatically submit forged requests to the vulnerable device.
The technical implementation of this CSRF vulnerability stems from the absence of proper authentication tokens or validation mechanisms in the password change form. When administrators access the device's web interface to modify their credentials, the system accepts requests containing sysUserName, sysPassword, and sysCfmPwd parameters without verifying the authenticity of the request source. This design flaw enables attackers to craft malicious HTML pages or exploit existing web content that submits these parameters to the device's administration interface, effectively hijacking the administrator's session and changing the password without their knowledge or consent.
The operational impact of this vulnerability is severe and far-reaching within network security contexts. An attacker who successfully exploits this CSRF flaw gains complete administrative control over the Xavi X7968 device, potentially leading to unauthorized network access, data exfiltration, configuration manipulation, and persistent backdoor establishment. The vulnerability particularly affects network infrastructure devices where administrative access is critical for maintaining security posture, making it a prime target for attackers seeking long-term network compromise. The remote nature of the attack means that exploitation can occur from anywhere on the internet, without requiring physical access or network proximity to the device.
Security professionals should recognize this vulnerability as a classic example of CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications. The flaw aligns with ATT&CK technique T1078.004, which covers valid accounts used for lateral movement, as the compromised administrative credentials would provide attackers with legitimate access to the device. Organizations should implement multiple mitigations including the deployment of anti-CSRF tokens in all administrative forms, implementation of strict referer header validation, and enforcement of session management best practices. Network segmentation and access control measures should also be strengthened to limit the potential impact of such compromises, while regular security audits should verify that all administrative interfaces properly implement CSRF protection mechanisms to prevent similar vulnerabilities from persisting in network infrastructure devices.
