CoreFTP is a focused file-transfer client and server product that, despite a narrow product scope, ranks among more prominent vendors in the vulnerability landscape, likely reflecting widespread adoption in enterprise and managed-service environments. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a strong tendency to acquire public exploit code; the exposure recurs through memory-safety and access-control weaknesses including buffer overflows, out-of-bounds writes, path traversal, and race conditions that are characteristic of native FTP implementations handling untrusted network input. Defenders should prioritize patching for this vendor and restrict FTP service exposure; live severity, exploitation, and exposure counts are shown alongside this summary.
