Description
C-Kermit 8.0.200 before 11.1.515 contains a path traversal vulnerability in doftpget() in ckcftp.c that allows malicious FTP servers to write files outside the intended directory. Attackers can return absolute paths, tilde names, or dot-dot components in NLST or MLSD listings during MGET /RECURSIVE to overwrite files like .bashrc, leading to code execution.
