suppaftp is vulnerable to Command Injection
59
Medium Risk
This Affects:
suppaftpTL;DR
The suppaftp FTP client writes command arguments to the control channel without validating them. Arguments that contain carriage return or line feed characters can terminate the intended command and add additional FTP commands onto the authenticated control connection. Affected operations are login, cwd, mkdir/rmdir, rm, rename, retr, stor, appe, list, site, and custom_command across the sync, tokio, and smol clients. The fix validates every command line before transmission and rejects any line containing CR or LF characters.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application passes input into FTP command arguments.
