CVE-2026-1688
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 security vulnerability has been detected in itsourcecode Directory Management System 1.0. The affected element is an unknown function of the file /admin/index.php. The manipulation of the argument Username leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used.
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 confidenceSQL injection vulnerability in itsourcecode Directory Management System 1.0 admin login page (/admin/index.php). The Username parameter accepts unsanitized user input that is directly concatenated into SQL queries, allowing remote attackers to manipulate database queries, potentially bypassing authentication or exfiltrating sensitive data.

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.
-
Confirm itsourcecode Directory Management System is installedLocate the web application root directory and identify if the Directory Management System (Clive 21) is present. Look for the /admin/index.php login page typically found in web application directories.Affected if The application is installed and accessible via web browser at /admin/index.php
-
Verify the installed version is 1.0Check application metadata files such as version.php, README.txt, or any version identifier within the application root directory. Cross-reference with the product name 'Clive 21 Directory Management System'.Affected if The installed version is exactly 1.0 (Clive 21 Directory Management System)
-
Inspect the admin login source codeAccess the file /admin/index.php on the web server and locate the SQL query handling code for the Username parameter. Search for SQL query construction involving the Username field.Affected if The Username parameter is processed via string concatenation into SQL queries rather than parameterized queries
-
Confirm the login form accepts user inputReview the HTML form at /admin/index.php to verify it contains a Username input field that is submitted to the backend without apparent input sanitization or validation.Affected if A Username input field exists in the login form that accepts direct user input
Your environment is affected if Clive 21 Directory Management System version 1.0 is installed and the /admin/index.php file handles the Username parameter via direct SQL string concatenation instead of prepared statements.

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 dataImplement parameterized queries (prepared statements) for all SQL operations involving user input, particularly the Username and Password fields in /admin/index.php. Validate and sanitize all inputs, and apply principle of least privilege to database accounts.
