Binardat 10G08-0800GSM network switch firmware version V300SP10260209 and prior do not implement rate limiting or account lockout on failed login attempts, enabling brute-force attacks against user credentials.

CVE-2026-27521 identifies a security weakness in the Binardat Ltd. 10G08-0800GSM network switch firmware (version V300SP10260209 and prior) where the device does not enforce any rate limiting or account lockout policies on failed authentication attempts. This flaw corresponds to CWE-307: Improper Restriction of Excessive Authentication Attempts. Without these protections, an attacker can perform unlimited brute-force attempts against user credentials remotely, as no authentication or user interaction is required to initiate login attempts. The vulnerability affects the network switch's management interface, which is typically accessible over the network, increasing the attack surface. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and low impact on confidentiality and integrity (VC:L, VI:L), with no impact on availability. Although no public exploits or patches are currently available, the vulnerability presents a significant risk of unauthorized access if attackers succeed in guessing valid credentials. This could lead to unauthorized configuration changes, interception or manipulation of network traffic, and potential lateral movement within the affected organization's network. The lack of rate limiting is a fundamental security oversight in authentication mechanisms, making this vulnerability a critical consideration for network administrators managing Binardat switches.
