| CVE-2026-70637 | 1 Hfiref0x | 1 Lightftp | 2026-08-06 | 5.9 Medium |
| 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-2026-67607 | 1 Hfiref0x | 1 Lightftp | 2026-08-03 | 5.9 Medium |
| LightFTP 2.3.1 contains a residual race condition vulnerability (an incomplete fix for CVE-2024-11144) in the worker_thread_cleanup() function of ftpserv.c that allows remote unauthenticated attackers to destabilize or crash the daemon by triggering unsynchronized access to shared per-connection state without holding the required mutex lock. Attackers can send a data-transfer command such as LIST followed immediately by ABOR to exploit the missing synchronization on shared context and detached thread id reuse, resulting in daemon destabilization or crash which can lead to a denial of service. The 2.3.1 patch only narrowed the timing window (an extra re-check and reordered cleanup), it never added the missing lock, so the underlying race remains. | ||||
| CVE-2023-24042 | 1 Hfiref0x | 1 Lightftp | 2025-12-08 | 7.5 High |
| A race condition in LightFTP through 2.2 allows an attacker to achieve path traversal via a malformed FTP request. A handler thread can use an overwritten context->FileName. | ||||
| CVE-2017-1000218 | 1 Hfiref0x | 1 Lightftp | 2025-12-08 | N/A |
| LightFTP version 1.1 is vulnerable to a buffer overflow in the "writelogentry" function resulting a denial of services or a remote code execution. | ||||
| CVE-2025-65403 | 2 Hfiref0x, Lightftp Project | 2 Lightftp, Lightftp | 2025-12-05 | 6.5 Medium |
| A buffer overflow in the g_cfg.MaxUsers component of LightFTP v2.0 allows attackers to cause a Denial of Service (DoS) via a crafted input. | ||||
