LightFTP vulnerabilities
3 known CVE vulnerabilities in LightFTP, translated and rated.
- CVE-2017-1000218Critical
LightFTP version 1.1 is vulnerable to a buffer overflow in the 'writelogentry' function resulting in denial of service or remote code execution.
- CVE-2026-70637Medium
LightFTP through 2.4 contains multiple data race vulnerabilities in ftpserv.c that allow anonymous attackers to cause undefined behavior by issuing LIST followed by ABOR commands without authentication. The control thread closes data_socket and file_fd descriptors while worker threads concurrently operate on the same fields in worker_thread_cleanup, allowing stale file descriptors to be reassigned by the OS and subsequently used by worker threads on unrelated resources, resulting in potential denial of service.
- CVE-2026-67607Medium
LightFTP 2.3.1 contains an incomplete fix for CVE-2024-11144, leaving a race condition in the worker_thread_cleanup() function. A remote unauthenticated attacker can send a LIST command followed by ABOR, causing daemon instability or crash (denial of service).
