Original Bulletin: 

- --------------------------BEGIN INCLUDED TEXT--------------------

MISP 2.4.134 released

In the previous version of MISP, the new Event Report functionality has been
introduced to edit, visualise and share reports in Markdown format, which
includes the ability to reference elements from within a MISP event.

In the current version, the Event Report has been extended to support the
automatic discovery of attributes, galaxies and tags from any website captured.

Video tag is not supported by your browser

This functionality allows the analysts to collect external reports and
automatically discover information which can be used in MISP. The Event Report
fetching capabilities require the misp-modules to be activated.

Optional A/V scanning in MISP

A new feature has been added to automatically scan attachments in MISP. The
functionality is completely optional and can be enabled in the global

ATT&CK sub-techniques

MISP now includes the ATT&CK sub-techniques as a MISP galaxy.

Example script for direct STIX ingestion into MISP

A new Ingest STIX script is available to show how to easily ingest STIX 1 and 2
files in MISP while using the parsing functionality of MISP core.

Security fix - CVE-2020-28043

A security vulnerability CVE-2020-28043 has been fixed. MISP through 2.4.133
allows SSRF in the REST client via the use_full_path parameter with an
arbitrary URL.

  o by using the full path parameter in the rest client, users could issue
    queries to any server
  o this becomes especially problematic when the MISP server is able to query
    other internal servers, as external users could trigger those
  o new server setting added that allows enabling the full path option, this is
    now disabled by default
  o new server setting added to add an override baseurl for the rest client,
    removing the need for the full path option in the first place (for example
    for the training VM with its port forwarding)
  o Thanks to Heitor Gouvea for reporting this vulnerability

Many bugs fixed and small improvements

  o Tag index has been improved with a simple view excludes eventtags /
    attributetags / sightings
  o Many UI improvements (thanks to Jakub Onderka for his continuous effort and
    attention to details)

A host of other improvements are documented in the complete changelog is


We would like to thank all the contributors, reporters and users who have
helped us in the past months to improve MISP and information sharing at large.
This release includes multiple updates in misp-objects, misp-taxonomies and
misp-galaxy .

As always, a detailed and complete changelog is available with all the fixes,
changes and improvements.
