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 vulnerability was determined in Campcodes Online Water Billing System 1.0. This affects an unknown function of the file /addclient1.php. Executing manipulation of the argument lname can lead to sql injection. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. Other parameters might be affected as well.

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 Campcodes Online Water Billing System 1.0 allows remote attackers to inject malicious SQL code through the lname parameter in /addclient1.php. The lack of input sanitization enables attackers to manipulate database queries, potentially leading to unauthorized data access or complete system compromise.

MitigationImplement parameterized queries (prepared statements) for all user inputs in addclient1.php, particularly the lname parameter and any other affected parameters identified during code review.

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 if Campcodes Online Water Billing System is installed
    Search the web server for files or directories containing 'water billing' or 'campcodes' in the name. Check for the presence of the application root directory.
    Affected if The application files are found on the system
  2. Verify the installed version is 1.0
    Look for a version file, about page, or check the application source code for a version indicator. Compare against the affected version range.
    Affected if The installed version is 1.0
  3. Confirm addclient1.php exists and is accessible
    Locate the file addclient1.php within the web application directory structure. Verify it is accessible via HTTP/HTTPS if the application is web-facing.
    Affected if The file addclient1.php exists and is web-accessible
  4. Check if the lname parameter is processed
    Examine the addclient1.php source code to verify the lname parameter is used in database queries. Search for SQL query patterns that include lname without parameterized queries.
    Affected if The lname parameter is used in SQL queries without prepared statements or input sanitization

If the system runs Campcodes Online Water Billing System version 1.0 with the addclient1.php file accessible and the lname parameter processed in SQL queries without sanitization, the environment is affected by CVE-2025-9492.

Mitigation

Implement parameterized queries (prepared statements) for all user inputs in addclient1.php, particularly the lname parameter and any other affected parameters identified during code review.

Recommended fix Moderate confidence

Latest available version from Campcodes (check github.com/campcodes for patched release)

  1. 1. Verify the current version of Online Water Billing System installed in your environment
  2. 2. Check Campcodes official repository (github.com/campcodes) or contact vendor for the latest version that includes SQL injection fixes
  3. 3. If a patched version exists, download it from the official source
  4. 4. Backup the current application database and files before upgrading
  5. 5. Replace the application files with the new version
  6. 6. Test all client creation and management functionality, especially the /addclient1.php endpoint and other form inputs
  7. 7. Verify that SQL injection is no longer possible by testing with malformed input in lname and other parameters
  8. 8. Monitor application logs for any suspicious SQL error messages
Caveat Test all billing workflows after upgrade as database schema may have changed
