Summary
by MITRE • 12/24/2025
Ecessa WANWorx WVR-30 versions before 10.7.4 contain a cross-site request forgery vulnerability that allows attackers to perform administrative actions without request validation. Attackers can craft a malicious web page with a hidden form to create a new superuser account by tricking an authenticated administrator into loading the page.

The vulnerability identified as CVE-2018-25151 affects Ecessa WANWorx WVR-30 devices running firmware versions prior to 10.7.4, representing a critical cross-site request forgery flaw that fundamentally compromises the device's administrative security posture. This vulnerability resides in the web-based management interface of the network appliance, where the system fails to implement proper request validation mechanisms for administrative operations. The flaw enables attackers to execute unauthorized administrative actions by exploiting the absence of anti-CSRF tokens or similar protective measures that should validate the authenticity of requests originating from legitimate administrative sessions. The vulnerability specifically targets the authentication and authorization framework of the device, allowing malicious actors to bypass normal security controls through deceptive web page construction.
The technical implementation of this vulnerability stems from the device's failure to enforce proper session validation and request origin verification during administrative operations. When an authenticated administrator accesses a maliciously crafted web page, the hidden form elements within the page automatically submit administrative requests to the vulnerable device without the administrator's knowledge or explicit consent. This occurs because the web interface does not require or validate anti-CSRF tokens, which are standard security mechanisms designed to prevent unauthorized requests from being executed on behalf of authenticated users. The vulnerability operates under CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications, and aligns with ATT&CK technique T1078.004 for Valid Accounts and T1566.001 for Spearphishing Attachment, as attackers can leverage social engineering to deliver malicious payloads that exploit this flaw. The device's authentication context remains active during the execution of these unauthorized requests, allowing the malicious form to create new superuser accounts with elevated privileges.
The operational impact of this vulnerability is severe and far-reaching, as it provides attackers with complete administrative control over the affected network appliance. Successful exploitation enables unauthorized users to establish persistent access through newly created superuser accounts, potentially leading to complete network compromise and unauthorized data exfiltration. The vulnerability affects not only the device's immediate security but also creates a potential attack vector for broader network infiltration, as the compromised device serves as a gateway for further malicious activities. Organizations using affected WVR-30 devices face significant risk of unauthorized network access, configuration changes, and potential data breaches. The vulnerability's exploitation requires minimal technical expertise and can be accomplished through simple web page crafting techniques, making it particularly dangerous in environments where administrators frequently browse untrusted websites or receive email attachments.
Mitigation strategies for CVE-2018-25151 center on immediate firmware updates to version 10.7.4 or later, which contain the necessary patches to address the CSRF vulnerability. Network administrators should also implement additional security measures including web application firewalls, strict access controls for administrative interfaces, and regular security assessments of network infrastructure devices. The implementation of proper anti-CSRF token validation mechanisms should be enforced across all administrative web interfaces, and organizations should conduct regular security awareness training for administrators to recognize potential social engineering attacks. Additionally, network segmentation and network access controls should be implemented to limit the potential impact of successful exploitation, while monitoring systems should be deployed to detect unauthorized administrative activities. Organizations should also consider implementing multi-factor authentication for administrative access and regularly review device configurations to ensure that administrative interfaces are not exposed to untrusted networks or public internet access.
