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 · unedited
LiquidFiles filetransfer server is vulnerable to a user enumeration issue in its password reset functionality. The application returns distinguishable responses for valid and invalid email addresses, allowing unauthenticated attackers to determine the existence of user accounts. Version 4.2 introduces user-based lockout mechanisms to mitigate brute-force attacks, user enumeration remains possible by default. In versions prior to 4.2, no such user-level protection is in place, only basic IP-based rate limiting is enforced. This IP-based protection can be bypassed by distributing requests across multiple IPs (e.g., rotating IP or proxies). Effectively bypassing both login and password reset security controls. Successful exploitation allows an attacker to enumerate valid email addresses registered for the application, increasing the risk of follow-up attacks such as password spraying.

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 confidence

LiquidFiles filetransfer server's password reset function returns different HTTP responses for valid versus invalid email addresses, enabling unauthenticated user enumeration. Prior to v4.2, only IP-based rate limiting exists and can be trivially bypassed using distributed requests. v4.2 introduces user-based lockout but does not prevent enumeration by default.

MitigationUpgrade to version 4.2 or later and explicitly enable/configure user-based lockout mechanisms to prevent both enumeration and brute-force attacks on the password reset function.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed LiquidFiles version
    Locate the version information for your LiquidFiles installation (typically available in the admin UI under System > About, or via CLI if available) and note the exact version number
    Affected if The installed version is lower than 4.2.0
  2. Test password reset response differences
    Submit two password reset requests: one with a known-valid email address and one with a random/invalid email address. Compare the HTTP status code, response body, and response time between the two requests
    Affected if The responses differ in content, timing, or HTTP status codes between valid and invalid emails, indicating user enumeration is possible
  3. Inspect rate limiting configuration
    Check the security or authentication settings in the LiquidFiles admin interface for rate limiting options related to password reset functionality
    Affected if Only IP-based rate limiting is configured without user-based lockout, or no user-based lockout mechanism is explicitly enabled
  4. Verify user-based lockout status
    Examine the security settings for any user-based account lockout or brute-force protection mechanisms on the password reset function
    Affected if User-based lockout is not enabled or configured on the password reset endpoint

Your environment is affected if the installed LiquidFiles version is below 4.2.0 and the password reset endpoint returns distinguishable responses for valid versus invalid accounts without user-based lockout protection.

Upgrade available Upgrade to 4.2.0 or later
Fixed in 4.2.0
Interim mitigation

Upgrade to version 4.2 or later and explicitly enable/configure user-based lockout mechanisms to prevent both enumeration and brute-force attacks on the password reset function.

Recommended fix High confidence

LiquidFiles 4.2.0 or later stable release

  1. 1. Backup the current LiquidFiles installation and database before proceeding with any changes.
  2. 2. Review the official LiquidFiles upgrade documentation at docs.liquidfiles.com for version-specific upgrade instructions.
  3. 3. Ensure the upgrade target environment meets the system requirements for version 4.2.0 or later.
  4. 4. Perform the upgrade to LiquidFiles version 4.2.0 or the latest stable release.
  5. 5. After upgrading, verify that the password reset functionality no longer returns distinguishable responses for valid versus invalid email addresses.
  6. 6. Consider configuring additional security settings such as enabling enhanced lockout policies if available in the admin interface.
Caveat Review release notes for any configuration or behavioral changes between current version and 4.2.0; test in non-production environment first
