CVE-2025-10100
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 was detected in SourceCodester Simple Forum Discussion System 1.0. This impacts an unknown function of the file /admin_class.php?action=login. Performing manipulation of the argument Username results in sql injection. It is possible to initiate the attack remotely. The exploit is now 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 SourceCodester Simple Forum Discussion System 1.0 allows remote attackers to inject malicious SQL queries through the Username parameter in the /admin_class.php?action=login endpoint. The lack of input sanitization or parameterized queries enables attackers to manipulate database queries, potentially gaining unauthorized administrative access.

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 vulnerable login scriptSearch for the file admin_class.php in your web root directory. This file typically resides in the /admin/ directory or the application root of the Simple Forum Discussion System.Affected if The file admin_class.php exists and contains a login action handler at the endpoint admin_class.php?action=login
-
Verify the application versionCheck your installed version of SourceCodester Simple Forum Discussion System (also known as Oretnom23 Simple Forum/discussion System). Look for version indicators in the source code, README, or any version file included with the installation.Affected if The installed version is exactly 1.0 (this is the only affected version)
-
Inspect the login function for SQL injection vulnerabilityOpen admin_class.php and locate the code handling the 'login' action. Search for the SQL query that processes the Username parameter. Check if the query uses parameterized queries (prepared statements) or direct string concatenation with the username input.Affected if The login code constructs SQL queries using the Username parameter directly without parameterized queries or input sanitization
-
Confirm the login endpoint is accessibleVerify the login page is accessible at the path /admin_class.php?action=login or similar admin login URL patterns used by this application.Affected if The login endpoint is publicly or internally accessible without additional authentication barriers
Your environment is affected if you have SourceCodester Simple Forum Discussion System version 1.0 installed, with the admin_class.php file containing a login function that uses direct string concatenation in SQL queries for the Username parameter.

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.
dbcve · scopedImplement prepared statements/parameterized queries for all database operations in the login function and apply input validation to prevent SQL injection attacks. Given the critical CVSS score and public exploit, immediate remediation is required.
- 1. Immediately restrict network access to the admin login page /admin_class.php?action=login using firewall rules or IP allowlisting
- 2. Implement a Web Application Firewall (WAF) rule to detect and block SQL injection attempts in the Username parameter
- 3. As a temporary workaround, add input validation/sanitization in admin_class.php to filter SQL injection payloads from the Username input before the query execution
- 4. Replace the vulnerable Simple Forum Discussion System with a maintained, actively supported forum software that receives security updates
- 5. If the application must continue running, audit all other parameters and files in the application for additional SQL injection or other vulnerabilities
