The CVE-2014-5395 vulnerability represents a critical cross-site request forgery flaw affecting Huawei HiLink devices including the E3276, E3236, and E5180s-22 models along with their respective firmware versions. This vulnerability resides in the web-based management interfaces of these telecommunications devices, creating a significant security risk for users who rely on these systems for network connectivity and communication services. The affected firmware versions span multiple release cycles, indicating a prolonged period during which these devices remained vulnerable to unauthorized manipulation. The vulnerability specifically impacts the authentication mechanisms within the device's web user interface, allowing malicious actors to exploit the system's trust relationship with legitimate users.
The technical implementation of this CSRF vulnerability stems from insufficient validation of request origins and lack of proper anti-CSRF tokens within the web interface requests. Attackers can craft malicious web pages or send specially crafted requests that, when executed by an authenticated user, will perform actions without the user's knowledge or consent. The vulnerability enables attackers to modify device configurations, send SMS messages, and potentially execute other unspecified operations that could compromise network security and user privacy. The attack vectors remain unspecified in the CVE description, which suggests that the vulnerability may manifest through multiple attack surfaces within the device's web interface. This lack of specificity in the attack vectors indicates that the vulnerability may affect various functional areas of the device's management interface, making it particularly dangerous as defenders cannot easily predict all potential attack surfaces.
The operational impact of this vulnerability extends beyond simple configuration changes, as it directly compromises the integrity and confidentiality of network communications managed by these devices. An attacker who successfully exploits this vulnerability could gain unauthorized access to the device's management functions, potentially leading to complete network compromise. The ability to send SMS messages through the device represents a significant concern, as it could be used for spamming, fraud, or as a vector for further attacks. The vulnerability affects devices that are commonly deployed in residential and small business environments, where users may not have advanced security awareness or protective measures in place. Network administrators and users who rely on these devices for internet connectivity face substantial risks, as the attack can be executed remotely without requiring physical access to the device.
The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and demonstrates characteristics consistent with ATT&CK technique T1566.001 for credential access through phishing and T1071.004 for application layer protocol usage. The affected Huawei devices represent a critical attack surface within home and small office networks, where these devices often serve as gateways to broader network infrastructure. Security professionals should note that the vulnerability affects multiple device models and firmware versions, indicating that the flaw was likely introduced in the core web interface implementation rather than being isolated to specific components. Organizations should prioritize updating all affected devices to the latest firmware versions provided by Huawei, as these updates typically include proper CSRF token implementation and enhanced authentication mechanisms. The vulnerability also highlights the importance of web application security testing, particularly for embedded systems and IoT devices that are often deployed without adequate security considerations. Network segmentation and monitoring solutions should be implemented to detect unusual patterns of configuration changes or SMS message sending that could indicate exploitation of this vulnerability.
