CVE-2023-40762
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 · uneditedUser enumeration is found in PHPJabbers Fundraising Script v1.0. This issue occurs during password recovery, where a difference in messages could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users.
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 confidenceUser enumeration vulnerability in PHPJabbers Fundraising Script v1.0 password recovery function allows attackers to distinguish between valid and invalid usernames through differing error messages, facilitating targeted brute force attacks against legitimate user accounts.

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.
-
Confirm PHPJabbers Fundraising Script v1.0 installationLocate the script installation directory and check version.php or similar version file within the application root or includes folderAffected if Version is exactly 1.0 (other versions may not be affected)
-
Locate the password recovery functionalityIdentify the password recovery or 'forgot password' page within the application, typically found at /index.php?controller=pjForgot or similar route under the public-facing web rootAffected if The password recovery module is accessible and enabled on the site
-
Test error response for non-existent usernameSubmit a clearly invalid username (e.g., 'nonexistentuser123') in the password recovery form and capture the exact error or status message returnedAffected if A specific error message is returned indicating the user does not exist
-
Test error response for existing usernameSubmit a username you know to be valid (e.g., an administrator account) in the password recovery form and capture the exact error or status message returnedAffected if A different or more informative message is returned compared to the invalid username test
-
Compare error messages for enumeration vulnerabilityCompare the exact wording and content of the responses from steps 3 and 4 - examine whether they reveal different information about username validityAffected if The error messages differ in content or specificity, revealing whether the username exists in the system
If the Fundraising Script v1.0 is installed and the password recovery returns different error messages for valid versus invalid usernames, the environment is vulnerable to user enumeration.

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 uniform error messaging for password recovery to prevent username enumeration; return the same response whether the username exists or not.
