Fail2Ban (version 0.8.10) 2013/06/12
Fail2Ban (version 0.8.11.pre1) 2013/10/30
================================================================================
ver. 0.8.11 (2013/11/XXX) - loves-unittests-and-tight-DoS-free-filter-regexes
-----------
In light of CVE-2013-2178 that triggered our last release we have put
a significant effort into tightening all of the regexs of our filters
to avoid another similar vulnerability. All filters have been updated
and some to catch more login/authentication failures and to support
for newer application versions. There are test cases for most log
cases of failures now.
As usual, if you have other examples that demonstrate that a filter is
insufficient, or if we have inadvertently introduced a regression,
please provide us with example log lines on the github issue tracker
http://github.com/fail2ban/fail2ban/issues and NOT on a random blog in
some obscure corner of the Internet.
- IMPORTANT incompatible changes:
Filter name changes:
* 'lighttpd-fastcgi' filter has been renamed to 'suhosin'
* 'sasl' has been renamed to 'postfix-sasl'
* 'exim' spam catching failregexes was split out into 'exim-spam'
These changes will require changing jail.{conf,local} if any of
those filters were used.
- Fixes:
Daniel Black & Marcel Dopita
* filter.d/apache-auth -- fixed and apache auth samples provide. Closes gh-286
Yaroslav Halchenko
* filter.d/common.conf -- make colon after [daemon] optional. Closes gh-267
* filter.d/apache-common.conf -- support apache 2.4 more detailed error
log format. Closes gh-268
* Backends changes detection and parsing. Close gh-223 and gh-103:
- Polling backend: detect changes in the files not only based on
mtime, but also on the size and inode. It should allow for
better detection of changes and log rotations on busy servers,
older python 2.4, and file systems with precision of mtime only
up to a second (e.g. ext3).
- All backends, possible race condition: do not read from a file
initially reported empty. Originally could have lead to
accounting for detected log lines multiple times.
- Do not crash if executing a command in fail2ban-client interactive
mode has failed (e.g. due to incorrect syntax). Closes gh-353

Filters are tricky. They need to:
* work with a variety of the versions of the software that generates the logs;
* work with the range of logging configuration options available in the
software;
* work with multiple operating systems;
* not make assumptions about the log format in excess of the software
(e.g. do not assume a username doesn't contain spaces and use \S+ unless
you've checked the source code);
* account for how future versions of the software will log messages
(e.g. guess what would happen to the log message if different authentication
types are added);
* not be susceptible to DoS vulnerabilities (see Filter Security below); and
* match intended log lines only.
Please follow the steps from Filter Test Cases to Developing Filter Regular
Expressions and submit a GitHub pull request (PR) afterwards. If you get stuck,
you can push your unfinished changes and still submit a PR -- describe
what you have done, what is the hurdle, and we'll attempt to help (PR
will be automagically updated with future commits you would push to
complete it).
Filter test cases
-----------------
Purpose:
Start by finding the log messages that the application generates related to
some form of authentication failure. If you are adding to an existing filter
think about whether the log messages are of a similar importance and purpose
to the existing filter. If you were a user of Fail2Ban, and did a package
update of Fail2Ban that started matching new log messages, would anything
unexpected happen? Would the bantime/findtime for the jail be appropriate for
the new log messages? If it doesn't, perhaps it needs to be in a separate
filter definition, for example like exim filter aims at authentication failures
and exim-spam at log messages related to spam.
Even if it is a new filter you may consider separating the log messages into
different filters based on purpose.
Cause:
Are some of the log lines a result of the same action? For example, is a PAM
failure log message, followed by an application specific failure message the
result of the same user/script action? If you add regular expressions for
both you would end up with two failures for a single action.
Therefore, select the most appropriate log message and document the other log
message) with a test case not to match it and a description as to why you chose
one over another.
With the selected log lines consider what action has caused those log
messages and whether they could have been generated by accident? Could
the log message be occurring due to the first step towards the application
asking for authentication? Could the log messages occur often? If some of
these are true make a note of this in the jail.conf example that you provide.
Samples:
It is important to include log file samples so any future change in the regular
expression will still work with the log lines you have identified.
The sample log messages are provided in a file under testcases/files/logs/
named identically as the corresponding filter (but without .conf extension).
Each log line should be preceded by a line with failJSON metadata (so the logs
lines are tested in the test suite) directly above the log line. If there is
any specific information about the log message, such as version or an
application configuration option that is needed for the message to occur,
include this in a comment (line beginning with #) above the failJSON metadata.
Log samples should include only one, definitely not more than 3, examples of
log messages of the same form. If log messages are different in different
versions of the application log messages that show this are encouraged.
Also attempt to inject an IP into the application (e.g. by specifying
it as a username) so that Fail2Ban possibly detects the IP
from user input rather than the true origin. See the Filter Security section
and the top example in testcases/files/logs/apache-auth as to how to do this.
One you have discovered that this is possible, correct the regex so it doesn't
match and provide this as a test case with "match": false (see failJSON below).
If the mechanism to create the log message isn't obvious provide a
configuration and/or sample scripts testcases/files/config/{filtername} and
reference these in the comments above the log line.
FailJSON metadata:
A failJSON metadata is a comment immediately above the log message. It will
look like:
# failJSON: { "time": "2013-06-10T10:10:59", "match": true , "host": "93.184.216.119" }
Time should match the time of the log message. It is in a specific format of
Year-Month-Day'T'Hour:minute:Second. If your log message does not include a
year, like the example below, the year should be listed as 2005, if before Sun
Aug 14 10am UTC, and 2004 if afterwards. Here is an example failJSON
line preceding a sample log line:
# failJSON: { "time": "2005-03-24T15:25:51", "match": true , "host": "198.51.100.87" }
Mar 24 15:25:51 buffalo1 dropbear[4092]: bad password attempt for 'root' from 198.51.100.87:5543
The "host" in failJSON should contain the IP or domain that should be blocked.
For long lines that you do not want to be matched (e.g. from log injection
attacks) and any log lines to be excluded (see "Cause" section above), set
"match": false in the failJSON and describe the reason in the comment above.
After developing regexes, the following command will test all failJSON metadata
against the log lines in all sample log files
./fail2ban-testcases testSampleRegex
Developing Filter Regular Expressions
-------------------------------------
Date/Time:
At the moment, Fail2Ban depends on log lines to have time stamps. That is why
before starting to develop failregex, check if your log line format known to
Fail2Ban. Copy the time component from the log line and append an IP address to
test with following command:
./fail2ban-regex "2013-09-19 02:46:12 1.2.3.4" "<HOST>"
Output of such command should contain something like:
Date template hits:
|- [# of hits] date format
| [1] Year-Month-Day Hour:Minute:Second
Ensure that the template description matches time/date elements in your log line
time stamp. If there is no matched format then date template needs to be added
to server/datedetector.py. Ensure that a new template is added in the order
that more specific matches occur first and that there is no confusion between a
Day and a Month.
Filter file:
The filter is specified in a config/filter.d/{filtername}.conf file. Filter file
can have sections INCLUDES (optional) and Definition as follows:
[INCLUDES]
before = common.conf
after = filtername.local
[Definition]
failregex = ....
ignoreregex = ....
This is also documented in the man page jail.conf (section 5). Other definitions
can be added to make failregex's more readable and maintainable to be used
through string Interpolations (see http://docs.python.org/2.7/library/configparser.html)
General rules:
Use "before" if you need to include a common set of rules, like syslog or if
there is a common set of regexes for multiple filters.
Use "after" if you wish to allow the user to overwrite a set of customisations
of the current filter. This file doesn't need to exist.
Try to avoid using ignoreregex mainly for performance reasons. The case when you
would use it is if in trying to avoid using it, you end up with an unreadable
failregex.
Syslog:
If your application logs to syslog you can take advantage of log line prefix
definitions present in common.conf. So as a base use:
[INCLUDES]
before = common.conf
[Definition]
_daemon = app
failregex = ^%(__prefix_line)s
In this example common.conf defines __prefix_line which also contains the
_daemon name (in syslog terms the service) you have just specified. _daemon
can also be a regex.
For example, to capture following line _daemon should be set to "dovecot"
Dec 12 11:19:11 dunnart dovecot: pop3-login: Aborted login (tried to use disabled plaintext auth): rip=190.210.136.21, lip=113.212.99.193
and then ^%(__prefix_line)s would match "Dec 12 11:19:11 dunnart dovecot:
". Note it matches the trailing space(s) as well.
Substitutions (AKA string interpolations):
We have used string interpolations in above examples. They are useful for
making the regexes more readable, reuse generic patterns in multiple failregex
lines, and also to refer definition of regex parts to specific filters or even
to the user. General principle is that value of a _name variable replaces
occurrences of %(_name)s within the same section or anywhere in the config file
if defined in [DEFAULT] section.
Regular Expressions:
Regular expressions (failregex, ignoreregex) assume that the date/time has been
removed from the log line (this is just how fail2ban works internally ATM).
If the format is like '<date...> error 1.2.3.4 is evil' then you need to match
the < at the start so regex should be similar to '^<> <HOST> is evil$' using
<HOST> where the IP/domain name appears in the log line.
The following general rules apply to regular expressions:
* ensure regexes start with a ^ and are as restrictive as possible. E.g. do not
use .* if \d+ is sufficient;
* use functionality of Python regexes defined in the standard Python re library
http://docs.python.org/2/library/re.html;
* make regular expressions readable (as much as possible). E.g.
(?:...) represents a non-capturing regex but (...) is more readable, thus
preferred.
If you have only a basic knowledge of regular repressions we advise to read
http://docs.python.org/2/library/re.html first. It doesn't take long and would
remind you e.g. which characters you need to escape and which you don't.
Developing/testing a regex:
You can develop a regex in a file or using command line depending on your
preference. You can also use samples you have already created in the test cases
or test them one at a time.
The general tool for testing Fail2Ban regexes is fail2ban-regex. To see how to
use it run:
./fail2ban-regex --help
Take note of -l heavydebug / -l debug and -v as they might be very useful.
TIP: Take a look at the source code of the application you are developing
failregex for. You may see optional or extra log messages, or parts there
of, that need to form part of your regex. It may also reveal how some
parts are constrained and different formats depending on configuration or
less common usages.
TIP: For looking through source code - http://sourcecodebrowser.com/ . It has
call graphs and can browse different versions.
TIP: Some applications log spaces at the end. If you are not sure add \s*$ as
the end part of the regex.
If your regex is not matching, http://www.debuggex.com/?flavor=python can help
to tune it:
* use regex from the ./fail2ban-regex output (to ensure all substitutions are
done) and replace <HOST> with (?&.ipv4). Make sure that regex type set to
Python;
* for the test data put your log output with the time removed;
- when you have fixed the regex put it back into your filter file.
Please spread the good word about debuggex - Serge Toarca is kindly continuing
its free availability to Open Source developers.
Finishing up:
If you've added a new filter, add a new entry in config/jail.conf. The theory
here is that a user will create a jail.local with [filtername]\nenable=true to
enable your jail.
So more specifically in the [filter] section in jail.conf:
* ensure that you have "enabled = false" (users will enable as needed);
* use "filter =" set to your filter name;
* use a typical action to disable ports associated with the application;
* set "logpath" to the usual location of application log file;
* if the default findtime or bantime isn't appropriate to the filter, specify
more appropriate choices (possibly with a brief comment line).
Submit github pull request (See "Pull Requests" above) for
github.com/fail2ban/fail2ban containing your great work.
Filter Security
---------------
Poor filter regular expressions are susceptible to DoS attacks.
When a remote user has the ability to introduce text that would match filter's
failregex, while matching inserted text to the <HOST> part, they have the
ability to deny any host they choose.
So the <HOST> part must be anchored on text generated by the application, and
not the user, to a extent sufficient to prevent user inserting the entire text
matching this or any other failregex.
Ideally filter regex should anchor at the beginning and at the end of log line.
However as more applications log at the beginning than the end, anchoring the
beginning is more important. If the log file used by the application is shared
with other applications, like system logs, ensure the other application that use
that log file do not log user generated text at the beginning of the line, or,
if they do, ensure the regexes of the filter are sufficient to mitigate the risk
of insertion.
Examples of poor filters
------------------------
1. Too restrictive
We find a log message:
Apr-07-13 07:08:36 Invalid command fial2ban from 1.2.3.4
We make a failregex
^Invalid command \S+ from <HOST>
Now think evil. The user does the command 'blah from 1.2.3.44'
The program diligently logs:
Apr-07-13 07:08:36 Invalid command blah from 1.2.3.44 from 1.2.3.4
And fail2ban matches 1.2.3.44 as the IP that it ban. A DoS attack was successful.
The fix here is that the command can be anything so .* is appropriate.
^Invalid command .* from <HOST>
Here the .* will match until the end of the string. Then realise it has more to
match, i.e. "from <HOST>" and go back until it find this. Then it will ban
1.2.3.4 correctly. Since the <HOST> is always at the end, end the regex with a $.
^Invalid command .* from <HOST>$
Note if we'd just had the expression:
^Invalid command \S+ from <HOST>$
Then provided the user put a space in their command they would have never been
banned.
2. Filter regex can match other user injected data
From the Apache vulnerability CVE-2013-2178
( original ref: https://vndh.net/note:fail2ban-089-denial-service ).
An example bad regex for Apache:
failregex = [[]client <HOST>[]] user .* not found
Since the user can do a get request on:
GET /[client%20192.168.0.1]%20user%20root%20not%20found HTTP/1.0
Host: remote.site
Now the log line will be:
[Sat Jun 01 02:17:42 2013] [error] [client 192.168.33.1] File does not exist: /srv/http/site/[client 192.168.0.1] user root not found
As this log line doesn't match other expressions hence it matches the above
regex and blocks 192.168.33.1 as a denial of service from the HTTP requester.
3. Application generates two identical log messages with different meanings
If the application generates the following two messages under different
circumstances:
client <IP>: authentication failed
client <USER>: authentication failed
Then it's obvious that a regex of "^client <HOST>: authentication
failed$" will still cause problems if the user can trigger the second
log message with a <USER> of 123.1.1.1.
Here there's nothing to do except request/change the application so it logs
messages differently.

# DEV Notes:
#
# This filter matches the authorization failures of Apache. It takes the log messages
# from the modules in aaa that return HTTP_UNAUTHORIZED, HTTP_METHOD_NOT_ALLOWED or
# HTTP_FORBIDDEN and not AUTH_GENERAL_ERROR or HTTP_INTERNAL_SERVER_ERROR.
#
# An unauthorized response 401 is the first step for a browser to instigate authentication
# however apache doesn't log this as an error. Only subsequent errors are logged in the
# error log.
#
# Source:
#
# By searching the code in http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/aaa/*
# for ap_log_rerror(APLOG_MARK, APLOG_ERR and examining resulting return code should get
# all of these expressions. Lots of submodules like mod_authz_* return back to mod_authz_core
# to return the actual failure.
#
# See also: http://wiki.apache.org/httpd/ListOfErrors
# Expressions that don't have tests and aren't common.
