CVE-2006-1643
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 login.php in Interact 2.1.1 allows remote attackers to execute arbitrary SQL commands via the user_name parameter. NOTE: the provenance of this information is unknown; the details are obtained from third party.
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 confidenceSQL injection vulnerability in login.php of Interact 2.1.1 allows remote attackers to execute arbitrary SQL commands via the user_name parameter. The lack of proper input sanitization or parameterized queries in the authentication logic enables attackers to manipulate SQL queries, potentially gaining unauthorized access to the application and underlying database.

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 Interact installation and versionLocate the Interact web application in your environment. Check for version information in the application files, such as a version file, about page, or the login page source. Compare your installed version to the affected ranges: 1.8.7, 1.9, 1.9.1, 2.0, 2.1, or 2.1.1.Affected if Your installed Interact version matches any of the affected versions listed.
-
Verify login.php is accessibleConfirm that the login.php file exists and is accessible via HTTP/HTTPS on your web server. This is typically found in the root directory of the Interact application.Affected if login.php is present and web-accessible in your Interact installation.
-
Check authentication implementationExamine the login.php file source code (if you have file access) for the user_name parameter handling. Look for whether the authentication logic uses raw SQL queries with user input or properly sanitized input/parameterized queries.Affected if The code uses unsanitized user input in SQL queries for the user_name parameter without prepared statements or input validation.
-
Assess network exposureDetermine if the login.php endpoint is exposed to untrusted networks or the public internet. Check firewall rules and web server access controls.Affected if The login.php endpoint is reachable from untrusted networks without additional access controls.
You are affected if your Interact installation version is 1.8.7, 1.9, 1.9.1, 2.0, 2.1, or 2.1.1 and the login.php file with the vulnerable authentication logic is accessible.

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 proper input validation and use parameterized queries/prepared statements for the user_name parameter in login.php. If a vendor patch is available, apply it; otherwise, upgrade to a supported version of Interact.
