CVE-2026-23678 is an OS command injection vulnerability categorized under CWE-78 affecting the Binardat Ltd. 10G08-0800GSM network switch firmware version V300SP10260209 and prior. The vulnerability resides in the traceroute diagnostic function accessible via the device's web management interface. Specifically, the hostname parameter does not properly neutralize special characters, allowing an attacker to inject the %1a character to manipulate the command line interface (CLI) commands executed by the device. An attacker with authenticated access to the web interface can leverage this flaw to execute arbitrary commands with the privileges of the network switch's management process. This can lead to full system compromise, including unauthorized configuration changes, data exfiltration, or denial of service. The vulnerability is remotely exploitable over the network without user interaction, but requires valid credentials. The CVSS v4.0 score is 8.7 (high severity), reflecting the ease of exploitation (low attack complexity), lack of required user interaction, and the significant impact on confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the vulnerability is published and should be addressed promptly.

The impact of CVE-2026-23678 is substantial for organizations relying on Binardat 10G08-0800GSM network switches, which are often deployed in critical telecommunications and enterprise network infrastructure. Successful exploitation can result in complete device compromise, allowing attackers to manipulate network traffic, disrupt network operations, or pivot to other internal systems. This can lead to data breaches, service outages, and loss of control over network environments. Given the network switch's role in routing and managing data flows, the vulnerability poses risks to network availability and integrity, potentially affecting large numbers of users and connected systems. The requirement for authentication limits exposure to insider threats or attackers who have obtained credentials, but the lack of user interaction and remote exploitability increases the attack surface. Organizations without timely mitigation may face operational disruptions and increased risk of advanced persistent threats targeting their network infrastructure.

To mitigate CVE-2026-23678, organizations should first verify if their Binardat 10G08-0800GSM network switches are running firmware version V300SP10260209 or earlier and prioritize upgrading to a fixed firmware version once released by the vendor. In the absence of an official patch, restrict access to the web management interface by implementing network segmentation and firewall rules limiting management access to trusted administrative hosts only. Enforce strong authentication mechanisms and regularly rotate credentials to reduce the risk of credential compromise. Monitor network switch logs and management interface access for unusual traceroute requests or suspicious command execution patterns indicative of exploitation attempts. Employ intrusion detection systems (IDS) with custom signatures targeting the injection pattern involving the %1a character in traceroute parameters. Additionally, consider disabling or restricting the traceroute diagnostic function if it is not essential for operations. Engage with Binardat support channels to obtain updates and guidance on remediation timelines.
