CVE-2026-24430 has a CVSS 3.1 base score of 7.5 (High). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. EPSS exploitation probability: 0.0%.

How to fix or mitigate CVE-2026-24430?

Within 24 hours: Identify all Tenda W30E V2 devices in your environment and document firmware versions; isolate devices from production networks if possible and restrict maintenance interface access to trusted networks only. Within 7 days: Disable the maintenance interface if operationally feasible; if required, change all admin credentials immediately and rotate any credentials that may have been exposed. Within 30 days: Replace affected devices with patched alternatives or devices from vendors with active security support; escalate to procurement to prevent future purchases of unsupported hardware.

AnalysisAIv1 – Mar 12, 2026

Shenzhen Tenda W30E V2 firmware through V16.01.0.19(5037) transmits administrative credentials in plaintext over unencrypted HTTP from the maintenance interface, allowing unauthenticated network attackers to intercept and obtain account credentials. Affected devices lack authentication requirements for accessing this interface, making credential theft trivial for anyone on the same network. No patch is currently available for this vulnerability.

Technical ContextAI · show details

Affects W30E Firmware. Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) disclose sensitive account credentials in cleartext within HTTP responses generated by the maintenance interface. Because the management interface is accessible over unencrypted HTTP by default, credentials may be exposed to network-based interception.

DescriptionCVE.org

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) disclose sensitive account credentials in cleartext within HTTP responses generated by the maintenance interface. Because the management interface is accessible over unencrypted HTTP by default, credentials may be exposed to network-based interception.

Executive ViewAI

Why It Matters

Tenda W30E V2 wireless devices expose administrator credentials in cleartext through their maintenance interface, creating immediate risk of unauthorized network access and data compromise. Any organization using affected firmware versions faces potential breach of network infrastructure credentials without a vendor patch currently available.

Business Impact: High

Compensating Controls

Disable the maintenance interface or restrict it to a protected management VLAN with strict firewall rules; implement network segmentation to isolate affected devices; deploy WAF rules blocking HTTP responses containing credential patterns; rotate administrative credentials immediately; monitor for suspicious authentication attempts; consider air-gapping devices until patch availability confirmed; implement mandatory VPN/802.1X authentication for any maintenance access.
