CyberRota Analysis
AI-GeneratedXlight FTP Server versions prior to 3.9.5 are vulnerable to an information disclosure flaw that enables unauthenticated attackers to retrieve the server's current GetTickCount() value by sending a specially crafted USER command. This vulnerability could potentially allow attackers to infer server uptime and other timing-related information, which may aid in further exploitation. Organizations using this FTP server should prioritize patching to mitigate the risk of information leakage.
Original NVD Description
Xlight FTP Server before 3.9.5 contains an information disclosure vulnerability that allows unauthenticated attackers to obtain the server's current GetTickCount() value by sending a USER command with a username ending in the :adm suffix. Attackers can trigger the admin protocol path within the standard FTP listener pre-authentication to leak timing information from the FTP 331 response without requiring a separate port or configuration change.
