CVE-2026-1410: Beetel 777VR1 UART missing authentication

A vulnerability was detected in Beetel 777VR1 up to 01.00.09/01.00.09_55. Impacted is an unknown function of the component UART Interface. The manipulation results in missing authentication. An attack on the physical device is feasible. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1410 affects Beetel 777VR1 broadband routers running firmware 01.00.09 or 01.00.09_55. The device UART interface reportedly lacks authentication, allowing a physically present attacker to access critical functions. Business urgency is moderate because exploitation requires physical device access and is described as difficult, but confidentiality, integrity, and availability impact can be high.

Executive priority

Treat this as a physical-access risk rather than a broad remote emergency. Prioritize affected routers in shared, public, branch, or customer-accessible locations. If no official fix is available, reduce physical access and plan replacement or compensating controls.

Technical view

The vulnerability is classified as missing authentication in the UART interface, mapped to CWE-287 and CWE-306. CVSS 3.1 is 6.4 with physical attack vector, high attack complexity, no privileges, no user interaction, and high C/I/A impact. VulDB states exploit material is public and the vendor did not respond to early disclosure.

Likely exposure

Exposure is mainly for organizations that deploy Beetel 777VR1 routers on affected firmware where attackers, insiders, contractors, or visitors could physically access devices. Remote internet exposure is not indicated by the provided sources.

Exploitation context

Sources state a public exploit exists, but exploitation requires physical access and is considered difficult. There is no KEV listing and no cited evidence of active exploitation in the wild.

Researcher notes

Evidence is limited to VulDB, the CVE record, and referenced public exploit material. The vulnerable UART function is not further specified in the provided bundle. Do not infer remote attackability or active exploitation. Vendor response and remediation status appear unresolved in the cited sources.

Mitigation direction

  • Inventory Beetel 777VR1 routers and record firmware versions.
  • Prioritize devices running 01.00.09 or 01.00.09_55.
  • Check Beetel or service-provider guidance for firmware updates or official mitigation.
  • Restrict physical access to routers, wiring closets, and customer-premises equipment.
  • Use tamper controls or inspections where physical access cannot be tightly controlled.
  • Consider replacement if no vendor-supported remediation is available.

Validation and detection

  • Confirm model and firmware version through approved asset-management or device-administration processes.
  • Review physical security around affected routers and UART-accessible areas.
  • Check vendor, ISP, or procurement channels for updated firmware advisories.
  • Look for unexplained device resets, configuration changes, or physical tampering signs.
  • Document whether affected devices are in public, shared, or controlled locations.
