CVE-2024-48572
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 User enumeration vulnerability in AquilaCMS 1.409.20 and prior allows unauthenticated attackers to obtain email addresses via the "Add a user" feature. The vulnerability occurs due to insufficiently validated user input being processed as a regular expression, which is then matched against email addresses to find duplicate entries.
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 confidenceAquilaCMS versions 1.409.20 and prior contains a user enumeration vulnerability in the 'Add a user' feature. Attackers can submit specially crafted input that is not properly validated before being used as a regular expression pattern. This regex is then matched against existing user email addresses in the system, allowing unauthenticated attackers to determine if specific email addresses are already registered.

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 AquilaCMS versionCheck the installed version of AquilaCMS by inspecting package.json, package-lock.json, or the admin dashboard version info. The version is typically found in the root directory or in the CMS about page.Affected if Version is 1.409.20 or lower (the CVE states versions prior to and including 1.409.20 are affected)
-
Verify Add a user endpoint accessibilityDetermine if the user registration endpoint (typically /api/users or /api/auth/register) is accessible without authentication. Check server configuration and API route definitions.Affected if The endpoint is exposed to unauthenticated users (no login required to access the 'Add a user' feature)
-
Confirm lack of regex sanitization in input validationInspect the backend code handling the 'Add a user' request, specifically the email input validation logic. Look for regex pattern matching where user-supplied input is used directly without escaping special characters.Affected if User input in the email field is used directly as a regex pattern without sanitizing special characters like . * + ? [ ] { } ( ) | \ ^ $
-
Test for user enumeration behaviorSubmit a crafted request to the Add a user endpoint with regex metacharacters in the email field (e.g., [email protected].* or [email protected]+). Compare response behavior to determine if the system reveals whether an email already exists based on regex matching.Affected if Submitting input with regex special characters produces different responses that reveal whether specific email addresses are registered in the system
Environment is affected if running AquilaCMS version 1.409.20 or lower with the Add a user endpoint accessible to unauthenticated users and without proper sanitization of regex special characters in the email input field.

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 to escape or whitelist regex special characters before using user input in pattern matching. Additionally, require authentication or implement rate limiting on the 'Add a user' endpoint to prevent automated enumeration.
