CVE-2026-9139
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTaiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 contains a hard-coded credential vulnerability in the embedded web configuration interface where authentication is implemented entirely in client-side JavaScript in login.zhtml, exposing static plaintext credentials in the page source. Unauthenticated attackers with network access can recover administrative credentials directly from the client-side validate() function to obtain full administrative access to the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Taiko AG1000-01A SMS Alert Gateway versions 7.3 and 8 contain hard-coded credentials embedded in client-side JavaScript (login.zhtml). The authentication logic resides entirely in the validate() function within the page source, exposing static plaintext administrative credentials. Unauthenticated attackers with network access can recover these credentials directly from the client-side code to gain full administrative access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Access the login pageNavigate to the device's login.zhtml page over HTTP/HTTPS (e.g., http://<device-ip>/login.zhtml)Affected if The page loads successfully and is accessible over the network
-
View page source codeRight-click on the login page and select 'View Page Source' or use browser developer tools (F12) to inspect the HTML contentAffected if The page source is visible and contains JavaScript code
-
Locate the validate() functionSearch within the page source for the string 'function validate' or 'validate()'Affected if A client-side validate() function exists in the JavaScript
-
Search for hardcoded credentialsWithin the validate() function or surrounding JavaScript, look for plaintext username and password strings (e.g., 'admin', 'password', credential variables assigned string literals)Affected if Hardcoded username and password values are present in the JavaScript code
-
Confirm client-side authenticationVerify that the validate() function performs authentication logic entirely in the browser without communicating with a server endpoint for credential validationAffected if Authentication logic runs entirely in the browser and credentials are checked client-side
If the login.zhtml page source contains a validate() function with hardcoded administrative credentials, the device is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataContact the vendor for a patched firmware version that removes hard-coded credentials and implements proper server-side authentication. Until a patch is available, isolate the device behind a firewall or disable remote administration to limit exposure.
