CVE-2025-6103
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 · uneditedA vulnerability, which was classified as critical, has been found in Wifi-soft UniBox Controller up to 20250506. Affected by this issue is some unknown functionality of the file /billing/test_accesscodelogin.php. The manipulation of the argument Password leads to os command injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceOS command injection vulnerability in Wifi-soft UniBox Controller's /billing/test_accesscodelogin.php script. The 'Password' parameter is not sanitized before being passed to a system call, allowing remote attackers to execute arbitrary OS commands by injecting shell metacharacters.

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.
-
Verify UniBox Controller installation existsLocate the web application's document root and confirm the presence of the /billing/ directory and test_accesscodelogin.php scriptAffected if The script /billing/test_accesscodelogin.php is present on the server
-
Confirm script is network accessibleAttempt to access the URL endpoint (e.g., GET/POST request to http://[host]/billing/test_accesscodelogin.php)Affected if The script responds to HTTP requests and accepts input via the Password parameter
-
Inspect code for input sanitizationExamine the test_accesscodelogin.php source code to verify whether the Password parameter undergoes sanitization before being used in system callsAffected if The Password parameter is passed directly to shell execution functions (such as exec, system, shell_exec, passthru) without sanitization or use of escapeshellarg/escapeshellcmd
-
Identify product versionCheck UniBox Controller version via admin interface, configuration files, or HTTP headers (look for version strings in HTML or HTTP responses)Affected if Unable to determine version or version falls within any affected release range provided by vendor
-
Verify web server configuration exposureReview web server logs or access logs for requests to /billing/test_accesscodelogin.php as indicators of potential exploitation attemptsAffected if Suspicious requests containing shell metacharacters (e.g., ;, |, &, $(), ``) in the Password parameter are observed in logs
The environment is affected if the /billing/test_accesscodelogin.php script exists, is accessible over the network, and processes the Password parameter without sanitization before shell execution.

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 dataSanitize all user input before use in system commands; prefer parameterized APIs or safe library functions over shell execution. Consider disabling the affected endpoint until a patch is available from the vendor.
