CVE-2005-3828
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 · uneditedSQL injection vulnerability in index.php in ActiveCampaign KnowledgeBuilder 2.4 and earlier allows remote attackers to execute arbitrary SQL commands via the article parameter.
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 index.php allows remote attackers to execute arbitrary SQL commands via the article parameter in ActiveCampaign KnowledgeBuilder 2.4 and earlier. The application fails to properly sanitize user input before using it in dynamic SQL queries.

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.
-
Identify KnowledgeBuilder versionLocate the installed version of ActiveCampaign KnowledgeBuilder by examining the application header, footer, or version file included with the softwareAffected if The installed version is 2.4 or any version earlier than 2.4
-
Locate vulnerable index.phpFind index.php in the web root directory of the KnowledgeBuilder installationAffected if index.php exists and is accessible in the application directory
-
Inspect article parameter handlingOpen index.php and search for code that handles the 'article' parameter from user request (GET/POST). Examine how this parameter is used in database queriesAffected if The 'article' parameter is used in SQL queries without sanitization or parameterized queries
-
Check for proper input validationLook for input validation functions, escaping functions (like mysql_real_escape_string), or use of prepared statements when the article parameter is incorporated into SQLAffected if No input sanitization or parameterized queries are found for the article parameter in SQL execution
You are affected if running KnowledgeBuilder version 2.4 or earlier and index.php contains direct use of the article parameter in dynamic SQL queries without sanitization.

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 dataImplement parameterized queries (prepared statements) or proper input validation/sanitization for the article parameter and all user-supplied inputs in index.php.
