IntelMQ Manager 2.1.1 Security Bugfix Release
by Sebastian Wagner 27 Apr '20

27 Apr '20

Dear community, The newest IntelMQ Manager release 2.1.1 fixes a critical security bug. Please never run the IntelMQ Manager without proper authentication in place! Installation instructions: https://github.com/certtools/intelmq-manager/blob/2.1.1/docs/INSTALL.md Bernhard Herzog (Intevation) discovered that the backend incorrectly handled messages given by user-input in the "send" functionality of the Inspect-tool of the Monitor component. An attacker with access to the IntelMQ Manager could possibly use this issue to execute arbitrary code with the privileges of the webserver. Updated deb/rpm-packages are already available in the repositories. Other changes: ### Backend - Fix misspelling of the environmental variable `INTELMQ_MANGER_CONTROLLER_CMD` to `INTELMQ_MANAGER_CONTROLLER_CMD` (an 'a' was missing). - Fix handling of POST variable `msg` of the message-sending functionality available in the Inspect-tool. ### Pages #### Monitor - Fix running commands with the "inspect" widget by fixing the definition of the `CONTROLLER_CMD` in the template (PR #194). ### Documentation - Update supported operating systems in Installation documentation (i.a. PR #191). ### Known issues * Missing CSRF protection (#111). * Graph jumps around on "Add edge" (#148). * wrong error message for new bots with existing ID (#152). * `ALLOWED_PATH=` violates CSP (#183). * Monitor page: Automatic log refresh reset log page to first one (#190). -- // Sebastian Wagner <wagner(a)cert.at> - T: +43 1 5056416 7201 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

Reverse DNS Expert - unusual behavior
by Tomislav Protega 31 Mar '20

31 Mar '20

Hi, recently I noticed that reverse DNS expert bot doesn't correctly apply the reverse lookup results for IP. Meaning, the right value (result) is not applied for the right JSON event. It's like it's skipping it and then applies it to other event. There are no errors in log file for the bot. For the illustration: Let say that hostname for IP 1.1.1.1 is "xx.yyy.zz", but instead the mentioned hostname becomes applied under wrong JSON event for the IP which in real has no PTR record in DNS. Of course, there are events which have applied right PTR record for the IP, but in rare situations. This case is not the issue with raw events which already contain hostname in origin feed. Anyone notice such behavor, or could take a look at already processed data and see if the "source.reverse_dns" has right value applied against IP? Regards, -- Tomislav

RIPE Expert Geolocation data (currently) not available anymore
by Sebastian Wagner 18 Mar '20

18 Mar '20

Hi, I just noticed, that RIPE currently does not provide geolocation information anymore as a result of the MaxMind data license change. That data can/could be queried with the IntelMQ RIPE expert. In case you are still relying on this information, please use another source for geolocation data, like the maxmind geolocation expert and local data. Unfortunately, the returned status code of the API call is 200 and the error is only detectable by another field. I am working on changes in the RPIE expert to detect this and raise a warning for it. best regards, Sebastian For example https://stat.ripe.net/data/maxmind-geo-lite/data.json?resource=131.130.254.… says: messages 0 0 "info" 1 "This data is currently unavailable due to maintenance. Please check official announcements for when it will be available again! https://stat.ripe.net/feedback" data_call_status "maintenance - this data call is in maintenance mode" -- // Sebastian Wagner <wagner(a)cert.at> - T: +43 1 5056416 7201 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

Long filenames and Generic Mail Attachment Fetcher
by Patrick Forsberg 28 Feb '20

28 Feb '20

Hi, I'm pretty sure some of you (at least Sebastian) is aware of this, but there is currently a problem with the intelmq.bots.collectors.mail.collector_mail_attach and attachments with long filenames. The error is not in the bot itself, but in the underlying imbox library that doesn't handle long filenames spread over multiple "filename*=" lines in Content-Disposition. The end result is that some attachments will probably fail to be extracted and it will look similar to the following line in the Collector log. Shadowserver-Mail-Attachment-Fetcher-Collector - INFO - Attachment sv.zip didn't match regex. There is a non merged pull request in the imbox Git repository to handle this but it hasn't been merged with the main repo. The solution is to patch imbox/parser.py I've attached my patch against the pip3 version of imbox (slightly different to the umerged Git pull request) Regards, Patrick Forsberg SUNET CERT

heads up: maxmind license updates (relevant for IntelMQ)
by L. Aaron Kaplan 09 Jan '20

09 Jan '20

Dear IntelMQ users, Sebix mentioned something that might be relevant for everyone using IntelMQ (or actually maxmind for the matter). (quote) "MaxMind has always been committed to an individual’s right to privacy on the internet. We welcome the burgeoning privacy regulations, such as GDPR and CCPA, for the benefit they can provide to internet citizens. However, these new legislative measures place restrictions that impact our ability to continue distributing our GeoLite2 databases on a public page under the Creative Commons Attribution-ShareAlike 4.0 International License." Maxmind has decided to change the download mechanism of the maxmind GeoLite 2 database. You now need to be registered and need a license key. Since I know that many IntelMQ users rely on maxmind for geolocation, you might want to register there and get a new license key and make sure it can be used for the most recent database version. More info at https://blog.maxmind.com/2019/12/18/significant-changes-to-accessing-and-us… All the best and a happy 2020! Aaron. -- // L.

Python 3.4 support coming to an end
by Sebastian Wagner 09 Dec '19

09 Dec '19

Hi, The upstream support of Python 3.4 ended already, this year in March the last bugfix was released. The current oldoldstable Debian version (jessie) uses this version, but I am not aware of any other popular system with an ancient Python version. Even CentOS 7 supports Python 3.6 (previously 3.4). As a consequence, more and more downstream libraries are dropping support for python 3.4, causing more maintenance work for me. I thus came to the point to slowly say Python 3.4 goodbye by -) first only running the CI tests on the core functionalities of IntelMQ for Python 3.4, ignoring other parts with optional requirements -) In the next minor release, only Python >= 3.5 will be supported I hope that this works for everyone.[0] Thanks, Sebastian [0]: If not, please contribute. -- // Sebastian Wagner <wagner(a)cert.at> - T: +43 1 5056416 7201 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

Re: [Intelmq-users] IntelMQ Error
by Sebastian Wagner 02 Dec '19

02 Dec '19

Hi Hatibu, I recommend to upgrade to a newer version, the latest release is 2.1.1. If this is a fresh installation, I recommend to remove the old version and start with the newer instead. Otherwise: It looks like your defaults.conf file (/etc/intelmq/defaults.conf or /opt/intelmq/etc/defaults.conf) is missing the `logging_level` parameter (default value INFO), but maybe there are more values missing.
