FileCodeBox

A vulnerability found in IPRateLimit implementation of FileCodeBox up to 2.2 allows remote attackers to bypass ip-based rate limit protection and failed attempt restrictions by faking X-Real-IP and X-Forwarded-For HTTP headers. This can enable attackers to perform DoS attacks or brute force share codes.

CVE-2025-51663 is a vulnerability identified in the IPRateLimit feature of FileCodeBox, a file sharing and collaboration platform, affecting versions up to 2.2. The vulnerability arises because the application trusts the X-Real-IP and X-Forwarded-For HTTP headers to determine the client's IP address for rate limiting purposes. Attackers can exploit this by spoofing these headers, effectively bypassing IP-based rate limiting and failed attempt restrictions. This allows an attacker to perform denial-of-service (DoS) attacks by overwhelming the service with requests or to brute force share codes without being blocked by the rate limiting mechanism. The vulnerability does not require authentication or user interaction, increasing its exploitability. The CVSS v3.1 base score is 7.5, reflecting a high severity due to network attack vector, low attack complexity, no privileges required, no user interaction, and a significant impact on availability. The weakness corresponds to CWE-305, which involves insufficient validation of input leading to security bypass. No patches or known exploits are currently documented, but the risk remains high given the nature of the flaw. The vulnerability impacts the confidentiality and integrity minimally but severely affects availability by enabling DoS attacks. The reliance on HTTP headers for IP identification is a common misconfiguration in web applications behind proxies or load balancers, making this a critical implementation flaw in FileCodeBox's rate limiting logic.
