Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) contain an authorization flaw in the user management API that allows a low-privileged authenticated user to change the administrator account password. By sending a crafted request directly to the backend endpoint, an attacker can bypass role-based restrictions enforced by the web interface and obtain full administrative privileges.
Security readout for executives and security teams
Plain-English summary
CVE-2026-24428 lets a low-privileged authenticated user on a Tenda W30E V2 change the administrator password. That can turn limited access into full device control. The issue is high urgency for organizations that use this device and allow non-admin users to authenticate to its management service.
Executive priority
Treat this as a priority remediation item where W30E V2 devices are present. A compromised low-privileged account could become full administrative control of network equipment, affecting availability, traffic control, and security posture.
Technical view
The source describes a CWE-863 incorrect authorization flaw in the W30E V2 user management API. Firmware up to and including V16.01.0.19(5037) is described as affected. The web interface enforces role restrictions, but the backend endpoint reportedly does not enforce them consistently.
Likely exposure
Exposure is likely limited to environments running Tenda W30E V2 devices, especially where the management interface is reachable by low-privileged authenticated users. The provided affected product metadata is sparse, so asset confirmation is required.
Exploitation context
The bundle does not report CISA KEV listing or active exploitation. Exploitation requires authenticated low-privileged access, but no user interaction and low attack complexity are indicated by the CVSS vector.
Researcher notes
Evidence supports incorrect authorization in the user management API, but the source bundle does not include a vendor fix version, exploit-in-the-wild confirmation, or detailed affected CPE data. Avoid assuming broader Tenda product impact without additional vendor evidence.
Mitigation direction
Inventory Tenda W30E V2 devices and record firmware versions.
Check Tenda guidance and apply any fixed firmware when available.
Restrict management interfaces to trusted administrator networks only.
Remove unnecessary low-privileged accounts from affected devices.
Monitor for unexpected administrator password changes.
Rotate administrator credentials after remediation and account review.
Validation and detection
Confirm whether any Tenda W30E V2 devices are deployed.
Compare firmware against V16.01.0.19(5037) and earlier.
Review management interface exposure and allowed source networks.
Audit local users for unnecessary low-privileged access.
Review device logs for administrator password changes.

CWE-863: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
