Detailsinfo

A vulnerability classified as critical has been found in LiquidFiles Filetransfer Server up to 4.2. This affects an unknown functionality. The manipulation with an unknown input leads to a password recovery vulnerability. CWE is classifying the issue as CWE-640. The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak. The impact remains unknown. The summary by CVE is:

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.
