I use pass and userdb with dict protocol in a similar way:
key passdb {
key = passdb^MAuth-User: %u^MAuth-Pass: %w^MAuth-Protocol:
%s^MClient-IP: %r
format = json
}
(^M is an \r character, inserted with vi CTRL-v + enter)
Until 2.2.24 this has worked, but 2.2.25 seems to convert that ASCII
13 into an ASCII 1 and an "r".
Python printout from what I get with 2.2.25:
'Lshared/passdb\x01rAuth-User: user\x01rAuth-Pass:
pass\x01rAuth-Protocol: pop3\x01rClient-IP: 1.2.3.4'
Is this change intentional? Why?
Hi!
Dict protocol escapes you newlines. You are expected to de-escape them
yourself.
Following escapes are done, you can de-escape them with your client.
\x00 => \x10
\x01 => \x11
\t => \x1t
\r => \x1r
\n => \x1n
Following up on this: dovecot 2.2.27 and 2.2.28 goes even further
(2.2.25 was OK).
If a user specifies a password with a % in it, dovecot silently
truncates it.
So for example if I specify (just to check this simple example is also bad):
key passdb {
key = %w
format = json
}
and a user tries to log in with the password 'Lofasznehogyma%', dovecot
sends the following into the dict socket:
'Lshared/Lofasznehogyma'
According to user reports, other characters may also be affected.
Could you please fix this?
