The CVE-2015-6378 vulnerability represents a critical cross-site request forgery flaw identified in Cisco DPQ3925 devices running EDVA version 5.5.2. This vulnerability resides within the web-based management interface of the device, creating a significant security risk that can be exploited by remote attackers without requiring any authentication credentials. The flaw specifically affects the device's ability to properly validate and authenticate web requests originating from external sources, allowing malicious actors to perform unauthorized actions on behalf of legitimate users.
The technical implementation of this CSRF vulnerability stems from the device's failure to properly implement anti-CSRF tokens or other sufficient validation mechanisms within its web interface. When a user authenticates to the device's management portal, the system should validate that subsequent requests originate from the authenticated user's session rather than from external malicious actors. However, the DPQ3925 device lacks adequate protection mechanisms, enabling attackers to craft malicious web pages or send specially crafted requests that exploit the trust relationship between the device and its authenticated users.
This vulnerability operates under the Common Weakness Enumeration CWE-352 category, which specifically addresses cross-site request forgery weaknesses in web applications and devices. The operational impact of this flaw is severe as it allows attackers to perform administrative actions such as changing network configurations, modifying user accounts, accessing sensitive device information, or potentially gaining complete control over the device. The vulnerability affects the device's authentication system by enabling unauthorized users to hijack active sessions, making it particularly dangerous for network infrastructure devices that require robust security controls.
The attack vector for this vulnerability is entirely remote, meaning that malicious actors can exploit it from outside the network without requiring physical access or network proximity. This characteristic aligns with ATT&CK technique T1566.001 which involves the use of malicious web content to gain access to systems. The vulnerability essentially allows attackers to perform actions that would normally require legitimate administrative privileges, potentially leading to complete network compromise and unauthorized access to connected systems. The affected Cisco DPQ3925 device serves as a potential entry point for attackers to escalate their privileges and move laterally within the network environment.
Mitigation strategies for this vulnerability include immediate firmware updates from Cisco that address the CSRF implementation flaw and ensure proper token validation mechanisms are in place. Network segmentation and firewall rules should be implemented to restrict access to the device's management interface to trusted administrative networks only. Additionally, implementing multi-factor authentication and regular security audits of network infrastructure devices can help reduce the overall risk exposure. Organizations should also consider disabling unnecessary web management interfaces and ensuring that only authorized personnel have access to administrative functions through secure channels.
