CVE-2026-24431: Tenda W30E V2 Web UI Reveals Passwords in Cleartext
Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) display stored user account passwords in plaintext within the administrative web interface. Any user with access to the affected management pages can directly view credentials.
Security readout for executives and security teams
Plain-English summary
This flaw lets an authenticated user who can reach the Tenda W30E V2 administrative web interface see stored account passwords in cleartext. The business risk is credential exposure: a lower-privileged or shared admin user may learn passwords that can be reused for device control or other systems.
Executive priority
Treat this as a high-priority credential exposure issue for affected Tenda W30E V2 deployments. Prioritize devices with shared administration, broad internal access, or exposed management interfaces. The source bundle does not name a patch, so remediation should start with access restriction and vendor guidance review.
Technical view
CVE-2026-24431 affects Shenzhen Tenda W30E V2 firmware up to and including V16.01.0.19(5037). The administrative UI exposes stored user account passwords in plaintext. The CVSS 4.0 score is 7.1, with network access, low complexity, low privileges, no user interaction, and high confidentiality impact.
Likely exposure
Exposure is most likely where Tenda W30E V2 devices are deployed and the management interface is reachable by multiple administrators, helpdesk users, or any non-dedicated account. Internet-reachable management interfaces would increase risk, but the bundle does not state external exposure is required.
Exploitation context
The source bundle indicates exploitation requires access to affected management pages with low privileges. It does not cite CISA KEV listing or active exploitation. The issue is disclosure through the UI, not a remote unauthenticated takeover based on the provided evidence.
Researcher notes
Evidence is limited to the CVE bundle and listed references. The affected-version metadata is sparse, but the description names firmware through V16.01.0.19(5037). The weakness maps to CWE-317 and the main impact is confidentiality of stored credentials.
Mitigation direction
Inventory Tenda W30E V2 devices and confirm firmware versions.
Restrict the administrative interface to trusted management networks or VPN access.
Limit administrative UI accounts to users with a clear operational need.
Rotate exposed device and reused credentials after validation.
Check Tenda guidance for fixed firmware or vendor-approved mitigations.
Validation and detection
Confirm whether deployed devices are W30E V2 and at or below V16.01.0.19(5037).
Review authorized management pages for plaintext rendering of stored user passwords.
Verify management UI access is blocked from untrusted networks.
Check whether any viewed credentials were reused on other systems.
Document vendor firmware status before closing remediation.
