Yes. busybox's ftpd has only anonymous mode.
In order to keep code small, it does not bother to
check usernames. So, you don't even need to login
as "anonymous", and username will do.
In fact, you don't even need to login.
You can connect and immediately start downloading stuff,
without issuing USER or PASS commands.

It is described in the usage text. You need to use -w option:
# ftpd --help
BusyBox v1.16.0.git (2009-08-30 17:07:12 CEST) multi-call binary
Usage: ftpd [-wvS] [-t N] [-T N] [DIR]
FTP server
ftpd should be used as an inetd service.
ftpd's line for inetd.conf:
21 stream tcp nowait root ftpd ftpd /files/to/serve
It also can be ran from tcpsvd:
tcpsvd -vE 0.0.0.0 21 ftpd /files/to/serve
Options:
-w Allow upload
-v Log to stderr
-S Log to syslog
-t,-T Idle and absolute timeouts
DIR Change root to this directory
If you do so, also use DIR, or else users will be able
to overwrite any file on the filesystem using ftp upload.
