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 has been found in itsourcecode Electronic Judging System 1.0. This affects an unknown part of the file /intrams/admin/login.php. The manipulation of the argument Username leads to sql injection. Remote exploitation of the attack is possible. The exploit has been disclosed to the public 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 Electronic Judging System 1.0 at /intrams/admin/login.php. The Username parameter is not properly sanitized, allowing remote attackers to inject malicious SQL queries through the login form.

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.
-
Locate the login.php fileSearch the web server document root for login.php, typically in the application root directory. Common paths may include /var/www/html/, /www/, or the application's web directory.Affected if The login.php file from itsourcecode Electronic Judging System exists in the web-accessible directory
-
Verify the application versionCheck for version indicators such as a version.php file, footer/branding text in the application, or a README/install file. Compare the identified version to the 1.0 release.Affected if The installed version is itsourcecode Electronic Judging System 1.0 or earlier
-
Inspect the Username parameter handling in login.phpOpen login.php and locate the code handling the Username POST or GET parameter. Look for SQL query construction where the Username variable is directly concatenated or inserted into the query string without proper escaping or parameterized queries.Affected if The Username field is used directly in a SQL query without prepared statements, parameter binding, or input sanitization
-
Confirm the login functionality is accessibleVerify the login page is accessible via HTTP/HTTPS to remote users. Check that the web server is running and the application is publicly or internally reachable.Affected if The login.php page is accessible and accepts user input for authentication
If the system runs itsourcecode Electronic Judging System 1.0 with a login.php that directly incorporates the Username parameter into SQL queries without parameterized prepared statements, the environment is vulnerable to CVE-2026-9383.

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 dataReplace dynamic SQL queries with parameterized queries/prepared statements in login.php. Validate and sanitize all user inputs. Apply vendor patch if available.
