CVE-2026-2702 in 777VR1
Summary
by MITRE • 02/19/2026
A security flaw has been discovered in Beetel 777VR1 up to 01.00.09. This issue affects some unknown processing of the component WPA2 PSK. Performing a manipulation results in hard-coded credentials. The attacker must have access to the local network to execute the attack. The complexity of an attack is rather high. The exploitability is assessed as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

The security vulnerability identified in Beetel 777VR1 firmware versions up to 01.00.09 represents a critical weakness in the wireless security implementation that affects the WPA2 Pre-Shared Key (PSK) processing component. This flaw constitutes a significant deviation from standard security practices where wireless credentials should be dynamically generated and securely managed rather than being embedded within the device firmware. The vulnerability stems from improper handling of WPA2 PSK parameters during the device configuration process, creating a scenario where hardcoded credentials are inadvertently exposed within the system's operational parameters.
The technical exploitation of this vulnerability requires an attacker to gain local network access to the affected device, establishing a baseline of network proximity that significantly limits the attack surface but does not eliminate the threat entirely. The complexity of the attack is rated as high due to the need for both physical or network proximity access and the requirement to manipulate specific firmware components that process WPA2 PSK information. This complexity factor aligns with attack patterns documented in the MITRE ATT&CK framework under the T1059.007 technique for command and scripting interpreter, where attackers must navigate through specific system interfaces to achieve credential exposure. The vulnerability manifests when the device processes WPA2 PSK information, potentially storing or transmitting hardcoded credentials in a manner that allows unauthorized access to the wireless network.
The operational impact of this vulnerability extends beyond simple credential exposure, as it fundamentally compromises the wireless security posture of any network utilizing affected Beetel 777VR1 devices. Once exploited, attackers can gain unauthorized access to the wireless network, potentially enabling further lateral movement within the network infrastructure and access to connected devices. The presence of public exploits demonstrates that this vulnerability has transitioned from theoretical concern to active threat, with malicious actors capable of leveraging the flaw without requiring advanced technical skills. This represents a significant concern for enterprise environments where wireless access points serve as entry points for broader network infiltration, and the lack of vendor response to early disclosure indicates a potential gap in the security supply chain that may leave users vulnerable for extended periods.
The absence of vendor response to early disclosure efforts creates additional risk for affected users, as it suggests either limited understanding of the vulnerability or inadequate security response protocols within the vendor's organization. This delay in remediation aligns with CWE-1004 weakness in security design where insufficient security measures are implemented in the development lifecycle, particularly in the areas of credential management and secure configuration. Organizations should implement immediate mitigations including network segmentation, monitoring for unauthorized wireless access points, and verification of device firmware versions to prevent exploitation. The vulnerability also highlights the importance of maintaining up-to-date firmware and implementing robust security monitoring procedures that can detect anomalous wireless network behavior. Given the public availability of exploits and the difficulty of attack execution, organizations should consider this vulnerability as a high-priority threat requiring immediate attention and remediation through firmware updates or network isolation measures.
