Security readout for executives and security teams
Plain-English summary
CVE-2026-1610 affects Tenda AX12 Pro V2 firmware 16.03.49.24_cn. The Telnet service reportedly contains hard-coded credentials, which can allow remote compromise of the device if reachable. The issue is rated critical, but the source notes high attack complexity and difficult exploitation. A public exploit is reported, but no KEV listing or confirmed active exploitation is provided.
Executive priority
Treat as urgent for environments using this exact Tenda model and firmware, particularly if management services are exposed. Prioritize discovery and access restriction now, while confirming whether Tenda has released corrective firmware.
Technical view
The vulnerability is categorized as CWE-259 and CWE-798: hard-coded password/credentials in the Telnet Service component. CVSS 4.0 is 9.2 with network attack vector, no privileges, no user interaction, high complexity, and high impact to vulnerable-system confidentiality, integrity, and availability. Affected version identified: Tenda AX12 Pro V2 16.03.49.24_cn.
Likely exposure
Exposure is limited to organizations or users running Tenda AX12 Pro V2 on firmware 16.03.49.24_cn, especially where Telnet or device management is reachable from untrusted networks. Internet-facing management access would increase business risk substantially.
Exploitation context
Sources state remote exploitation is possible and a public exploit exists, but exploitation is described as difficult and high complexity. The provided data does not show CISA KEV inclusion or confirmed active exploitation in the wild.
Researcher notes
Evidence is primarily from CVE/VulDB records and a referenced public issue. The vulnerable functionality is not further detailed beyond the Telnet Service. No patch version is named in the provided sources. Avoid assuming other Tenda models or firmware are affected without vendor confirmation.
Mitigation direction
- Identify AX12 Pro V2 devices and confirm firmware version.
- Restrict Telnet and management access to trusted networks only.
- Disable Telnet if not operationally required.
- Check Tenda guidance for updated firmware or vendor mitigation.
- Replace or isolate devices if no vendor fix is available.
Validation and detection
- Inventory Tenda AX12 Pro V2 assets across all sites.
- Verify whether firmware 16.03.49.24_cn is installed.
- Confirm whether Telnet service is enabled or reachable.
- Review perimeter exposure of router management interfaces.
- Monitor vendor and CVE sources for fix updates.
