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 found in itsourcecode Electronic Judging System 1.0. This vulnerability affects unknown code of the file /admin/edit_team.php. The manipulation of the argument num_id results in sql injection. The attack may be launched remotely. The exploit has been made public and could 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 · moderate confidence

A SQL injection vulnerability exists in the /admin/edit_team.php file of itsourcecode Electronic Judging System 1.0. The 'num_id' parameter is not properly sanitized, allowing remote attackers to inject arbitrary SQL queries. This high-severity (CVSS 7.3) flaw could enable unauthorized database access, data exfiltration, or full system compromise.

MitigationReplace dynamic SQL queries in edit_team.php with parameterized queries (prepared statements) to properly sanitize the num_id parameter input. Review and audit other files in the application for similar SQL injection vulnerabilities as a precautionary measure.

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 Electronic Judging System is installed
    Search the web root directory for itsourcecode Electronic Judging System files, or check for the presence of /admin/ directory and edit_team.php
    Affected if The system is not installed or the files are not present, the vulnerability does not apply
  2. Verify the product version is 1.0
    Check version.php, README, or any version file in the application root for version number; compare against the affected version 1.0
    Affected if The installed version is not 1.0, the specific vulnerability may not apply
  3. Confirm /admin/edit_team.php exists
    Locate and verify the presence of edit_team.php in the /admin/ directory of the web application
    Affected if The file edit_team.php does not exist, the vulnerability cannot be exploited
  4. Check if admin interface is accessible
    Attempt to access the /admin/ login page or edit_team.php directly via HTTP/HTTPS to determine if the admin panel is exposed
    Affected if The admin interface is not accessible (e.g., behind authentication or network restriction), the SQL injection is not exploitable remotely
  5. Inspect the num_id parameter handling in edit_team.php
    Review the source code of edit_team.php to confirm the num_id parameter is used in a database query without proper sanitization or prepared statements
    Affected if The num_id parameter uses parameterized queries or is properly sanitized, the vulnerability may be mitigated

A user is affected if they run Electronic Judging System version 1.0 with the /admin/edit_team.php file accessible and the num_id parameter used in unsanitized SQL queries
