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 · unedited
A security flaw has been discovered in SourceCodester Water Billing System 1.0. This impacts an unknown function of the file /viewbill.php. The manipulation of the argument ID results in sql injection. The attack may be launched remotely. The exploit has been released to the public and may be exploited.

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 confidence

SQL injection vulnerability in SourceCodester Water Billing System 1.0 allows remote attackers to inject malicious SQL queries via the ID parameter in /viewbill.php. The lack of input sanitization or parameterized queries enables complete database compromise.

MitigationReplace dynamic SQL queries in viewbill.php with prepared statements/parameterized queries, implement input validation on the ID parameter, and apply principle of least privilege to database accounts.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Water Billing System version
    Locate the application source files and check version identifiers in configuration files, readme files, or the main index page. Common locations include version.php, README.txt, or the system header/footer files.
    Affected if The installed version is Janobe Water Billing System 1.0 exactly
  2. Locate the viewbill.php file
    Search the web application directory for the file viewbill.php. This is typically found in the root web directory or a subdirectory containing billing modules.
    Affected if The file viewbill.php exists in the web application structure
  3. Verify the ID parameter is accepted
    Access the viewbill.php page via a web browser or curl request and observe if the ID parameter is processed. Test by submitting a request such as /viewbill.php?id=1 and verify the application responds.
    Affected if The application accepts and processes an ID parameter in viewbill.php without immediate error
  4. Check for SQL injection vulnerability
    Examine the viewbill.php source code for direct use of the ID parameter in SQL queries without prepared statements, parameter binding, or input sanitization functions such as mysqli_prepare or PDO::prepare.
    Affected if The code contains unsanitized SQL queries using the ID parameter (e.g., SELECT * FROM bills WHERE ID='$id' without prepare() statements)
  5. Confirm database user privileges
    Review the database configuration file (commonly config.php, db.php, or similar) to identify the database user credentials used by the application.
    Affected if The application database user has elevated privileges (such as DROP, CREATE, or FILE privileges) that could be exploited through SQL injection

Your environment is affected if you are running Janobe Water Billing System version 1.0 with viewbill.php accessible and the ID parameter processed through unsanitized SQL queries.
