Kevin Maradona 6c705d572b filter.d/nginx-limit-req.conf: nginx limit-req log-level can be set to warn or error therefore having this regex will include both of them. 2017-12-05 22:31:54 +01:00

Avoid injection using quotes after `auth` command;
Added non-greedy fallback for quoted something (with lookahead simulated possessive greedy catch of non-quoted parts `[^"]*(?=")`).
Note that because host-info's are hereafter (with foreign input in-between), we would not use greedy or non-greedy catch-alls (`.*` or `.*?`) here (preventing performance losses).

Serg G. Brester f59df2e156
Avoid any injecting on protocol (e. g. tries using camel-case)
The phrase "AUTH command used when not advertised" is precise enough as anchor here, so prevent by any foreign-input (any auth protocol error).

Exim failregex: Include lower/mixed case AUTH
When reporting the error `AUTH command used when not advertised`, Exim
starts with `SMTP protocol error in "........."`. Here, Exim logs the
SMTP command as it was provided by the connecting client.
https://github.com/Exim/exim/blob/exim-4_89+fixes/src/src/smtp_in.c#L2850

According to RFC 5321 (SMTP) "[..] a command verb [..] MAY be encoded
in upper case, lower case, or any mixture of upper and lower case with
no impact on its meaning."
https://tools.ietf.org/html/rfc5321#section-2.4

Lower case `auth login` brute-force attempts were seen in the wild and
were not caught by the current failregex.

This commit makes the failregex case-insensitive for the `AUTH`
command, so that lower case (`auth`) or mixed case (`aUtH`) now also
match. The failregex was already case-insensitive for the command
arguments (e.g. `AUTH login` already matched).

dovecot: Match also when user field is empty
Commit 5678d08 of 2016-11-26 changed:

    ( user=<\S*>,)?

to:

    ( user=<[^>]+>,)?

The change from `*` (zero or more times) to `+` (one or more times) may
not have been intended. It will miss lines containing, for example:

    Aborted login (tried to use disallowed plaintext auth): user=<>

This commit reverts the `+` back to `*`.
