CVE-2014-9151
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 · uneditedThe Services module 7.x-3.x before 7.x-3.10 for Drupal does not properly limit the rate of authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack on the administrative password.
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 confidenceThe Drupal Services module 7.x-3.x before version 7.x-3.10 lacks proper rate limiting on its authentication endpoints, allowing unlimited authentication attempts from a single source. This enables remote attackers to perform brute-force attacks against administrative passwords without being blocked or throttled.

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 Services module versionNavigate to Drupal admin panel, go to Extend or Modules page, locate the Services module, and note the version number displayed. Alternatively, check the services.info file in the modules directory for the version line.Affected if The installed version is 7.x-3.9 or any 7.x-3.x version prior to 7.x-3.10.
-
Verify authentication endpoint existsCheck your Services module configuration at Structure > Services (or /admin/structure/services). Look for any endpoint that has the Authentication resource enabled or exposed.Affected if An endpoint is configured and the authentication resource is enabled or accessible.
-
Confirm rate limiting is absentReview the Services module settings at Configuration > Services Authentication or within the endpoint configuration. Check for any rate limiting, flood control, or throttling settings on authentication-related resources.Affected if No rate limiting, flood control, or attempt throttling is configured on the authentication endpoint.
-
Test endpoint accessibilityIf you have access, make a test authentication request to the endpoint URL (typically /api/user/login or similar endpoint path). Note whether the server returns any rate limit headers or enforces any attempt restrictions.Affected if The endpoint accepts authentication requests without imposing any visible limits on repeated attempts from the same source.
You are affected if the Services module version is 7.x-3.9 or earlier AND an authentication endpoint is enabled without rate limiting configured.

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 the Drupal Services module to version 7.x-3.10 or later, which implements proper rate limiting on authentication attempts. Additionally, consider implementing web application firewall (WAF) rules or additional server-side rate limiting as a defense-in-depth measure.
