CVE-2026-27518 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the administrative web interface of Binardat Ltd.'s 10G08-0800GSM network switch firmware version V300SP10260209 and prior. The vulnerability arises because the firmware does not implement CSRF tokens or other anti-CSRF mechanisms to protect state-changing operations. As a result, an attacker can craft a malicious web page that, when visited by an authenticated administrator, causes the browser to unknowingly send unauthorized commands to the switch. These commands could alter network configurations, potentially compromising network integrity or availability. The vulnerability is remotely exploitable over the network without requiring prior authentication or elevated privileges, but it does require the administrator to be logged in and to interact with the attacker's content (user interaction). The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:A), and limited impact on confidentiality and integrity but no impact on availability. No patches or mitigations have been officially released yet, and there are no known exploits in the wild. This vulnerability highlights the importance of implementing CSRF protections in network device management interfaces to prevent unauthorized configuration changes that could lead to network disruption or compromise.

The primary impact of this vulnerability is unauthorized modification of network switch configurations by an attacker leveraging an authenticated administrator's session. This can lead to misconfigurations that disrupt network traffic, degrade performance, or create backdoors for further exploitation. In critical infrastructure environments, such unauthorized changes could cause significant operational outages or security breaches. Since the attack requires user interaction, the risk is somewhat mitigated, but social engineering or phishing campaigns targeting network administrators could increase exploitation likelihood. The lack of confidentiality and availability impact reduces the risk of data leakage or direct denial of service, but integrity of network configurations is at risk. Organizations relying on Binardat 10G08-0800GSM switches in their network core or edge infrastructure could face operational disruptions and increased exposure to subsequent attacks if this vulnerability is exploited.

1. Implement strict network segmentation and access controls to limit administrative interface exposure to trusted networks only. 2. Use multi-factor authentication (MFA) for administrative access to reduce the risk of compromised credentials being exploited. 3. Educate administrators to avoid clicking on suspicious links or visiting untrusted websites while logged into network device management consoles. 4. Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block CSRF attack patterns targeting the administrative interface. 5. Monitor administrative logs for unusual configuration changes or access patterns indicative of CSRF exploitation. 6. Contact Binardat Ltd. for firmware updates or patches addressing CSRF protections and apply them promptly once available. 7. If possible, implement custom CSRF tokens or session validation mechanisms via configuration or proxy solutions as an interim protective measure. 8. Regularly audit network device configurations to detect unauthorized changes early.
