dont use rcon if you can help it. rcon_password ""

install amx or am and use the admin_rcon funcs. Much safer.

Personally, The only thing I am afraid of is someone gaining RCON to my
servers. Is there anyway to set the rcon password in the command line as
opposed to server.cfg? I am still aware of the inherent risk of the rcon
password in the log files, but the amount of time I actually use rcon, as
compared to the total amount  of log files... I'd almost be willing to give
someone with that much patience rcon.

Florian is right with his statement. I tried this exploit by myself on
my servers and in the big sens it work, but not all like I expected.
In cs1.5 you can download any file below cstrike like server.cfg oder
addons/amx/users.ini and so on. In cs1.6 I was not able to download the
server.cfg as every time cs creates at startup new files. And also after
deleting while cs is running in steam, it will not download them. But
other help config files like test.cfg will be downloaded without a hassle.
That means, it is not as easy in cs1.6 as in 1.5 to get rcon access. But
on the other hand it is no problem to generate a directory called 'logs'
and make e.g. 'cmd dlfile logs/L1120000.log'. And if you used your rcon
anytime during that timeperiod of the logfile, the rcon is standing
there in plain text.
I also tried to trick the dlfile to get access above the cstrike
directory with a few unix-specific chars, tried to call sh oder ln but
all failed. At least this seems to be save now.

I switched of sv_allowdownload on all servers and it seems not
vulnerable anymore.

cheers,
