CVE-2009-4084
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 the search feature in e107 0.7.16 and earlier allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
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 the search feature of e107 CMS versions 0.7.16 and earlier allows remote unauthenticated attackers to execute arbitrary SQL commands through unsanitized input in the search functionality.

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 e107 CMS installationLocate the e107 version file, typically found in e107_config.php or by checking the footer/admin area of the CMS for the version numberAffected if Installed version is 0.7.16 or lower, or specifically matches 0.6_10, 0.6_11, 0.6_12, 0.6_13, 0.6_14, 0.6_15, 0.6_15a, 0.7, 0.7.1, 0.7.2, or 0.7.3
-
Confirm search feature is enabledCheck the e107 admin panel under Plugins or Modules to verify the search plugin/module is installed and activeAffected if The search functionality is enabled and accessible on the site
-
Inspect search feature configurationExamine the search plugin files in the e107_plugins directory, specifically looking at how user input is handled in search queriesAffected if The search code does not use parameterized queries and accepts unsanitized user input directly into SQL queries
-
Verify search endpoint accessibilityAttempt to access the search functionality via the web interface (typically /search.php or similar) without authenticationAffected if The search feature is reachable without authentication and accepts query parameters
You are affected if your e107 version is 0.7.16 or earlier (specifically 0.6_10 through 0.7.3) and the search feature is enabled and accessible without authentication.

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 dataUpgrade to e107 version 0.7.17 or later; alternatively, implement proper input validation and parameterized queries in the search feature code.
