CVE-2019-25611Public exploit

Root code execution via unbounded configuration copy

Published Mar 22, 2026 · Updated Mar 22, 2026

Stack buffer overflow in MiniFtp allows local users to execute arbitrary code as root through a crafted miniftpd.conf file. parseconf_load_setting passes 128-byte key and value arrays to str_split, which copies text after the equals sign with unbounded strcpy. The user must be able to replace the configuration file before a privileged operator starts the server; a successful overwrite redirects root-process control flow.
