Security Advisories and Reporting Security Vulnerabilities

Reporting security vulnerabilities is of great importance for us, as MISP is used in multiple critical infrastructures.

In the case of a security vulnerability report, we ask the reporter to send it directly to CIRCL, if possible encrypted with the following GnuPG key: CA57 2205 C002 4E06 BA70 BE89 EAAD CFFC 22BD 4CD5. We usually fix reported and confirmed security vulnerabilities in less than 48 hours, followed by a software release containing the fixes within the following days.

If you report security vulnerabilities, do not forget to tell us if and how you want to be acknowledged and if you already requested CVE(s). Otherwise, we will request the CVE(s) directly.

As one of the critical user-bases of MISP consists of the CSIRT community, it is our duty to clearly state which bug could be abused and have a security impact on a MISP instance. CVE assignment is performed even for minor bugs suspected of having a security impact. This allows every user with MISP instances set up in their environments to understand which bugs could impact their security.

We firmly believe that, even though unfortunately it is often not regarded as common practice in our industry, being as transparent as possible about vulnerabilities, no matter how minor, is of crucial importance. At MISP Project, we care about the security of our users and prefer to have a high number of published CVEs rather than sweeping some of them under the rug.


  • CVE-2015-5719 <= MISP 2.3.92 - app/Controller/TemplatesController.php in Malware Information Sharing Platform (MISP) before 2.3.92 does not properly restrict filenames under the tmp/files/ directory, which has unspecified impact and attack vectors.
  • CVE-2015-5720 <= MISP 2.3.89 - Multiple cross-site scripting (XSS) vulnerabilities in the template-creation feature in Malware Information Sharing Platform (MISP) before 2.3.90 allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) add.ctp, (2) edit.ctp, and (3) ajaxification.js.
  • CVE-2015-5721 <= MISP 2.3.89 - Malware Information Sharing Platform (MISP) before 2.3.90 allows remote attackers to conduct PHP object injection attacks via crafted serialized data, related to TemplatesController.php and populate_event_from_template_attributes.ctp.
  • CVE-2017-7215 <= MISP 2.4.68 - Cross site scripting in some view elements in the index filter tool in app/webroot/js/misp2.4.68.js and the organisation landing page in app/View/Organisations/ajax/landingpage.ctp of MISP before 2.4.69 allows remote attackers to inject arbitrary web script or HTML.
  • CVE-2017-13671 <= MISP 2.4.79 - app/View/Helper/CommandHelper.php in MISP before 2.4.79 has persistent XSS via comments. It only impacts the users of the same instance because the comment field is not part of the MISP synchronisation.
  • CVE-2017-14337 <= MISP 2.4.79 - When MISP before 2.4.80 is configured with X.509 certificate authentication (CertAuth) in conjunction with a non-MISP external user management ReST API, if an external user provides X.509 certificate authentication and this API returns an empty value, the unauthenticated user can be granted access as an arbitrary user.
  • CVE-2017-15216 <= MISP 2.4.81 - MISP before 2.4.81 has a potential reflected XSS in a quickDelete action that is used to delete a sighting, related to app/View/Sightings/ajax/quickDeleteConfirmationForm.ctp and app/webroot/js/misp.js.
  • CVE-2017-16802 <= MISP 2.4.82 - In the sharingGroupPopulateOrganisations function in app/webroot/js/misp.js in MISP 2.4.82, there is XSS via a crafted organisation name that is manually added.
  • CVE-2017-16946 <= MISP 2.4.82 - The admin_edit function in app/Controller/UsersController.php in MISP 2.4.82 mishandles the enable_password field, which allows admins to discover a hashed password by reading the audit log.
  • CVE-2018-6926 <= MISP 2.4.87 - In app/Controller/ServersController.php in MISP 2.4.87, a server setting permitted the override of a path variable on certain Red Hed Enterprise Linux and CentOS systems (where rh_shell_fix was enabled), and consequently allowed site admins to inject arbitrary OS commands. The impact is limited by the setting being only accessible to the site administrator.
  • CVE-2018-8948 <= MISP 2.4.89 - In MISP before 2.4.89, app/View/Events/resolved_attributes.ctp has multiple XSS issues via a malicious MISP module.
  • CVE-2018-8949 <= MISP 2.4.89 - An issue was discovered in app/Model/Attribute.php in MISP before 2.4.89. There is a critical API integrity bug, potentially allowing users to delete attributes of other events. A crafted edit for an event (without attribute UUIDs but attribute IDs set) could overwrite an existing attribute.
  • CVE-2018-11245 <= MISP 2.4.91 - app/webroot/js/misp.js in MISP 2.4.91 has a DOM based XSS with cortex type attributes.
  • CVE-2018-11562 <= MISP 2.4.91 - An issue was discovered in MISP 2.4.91. A vulnerability in app/View/Elements/eventattribute.ctp allows reflected XSS if a user clicks on a malicious link for an event view and then clicks on the deleted attributes quick filter.
  • CVE-2018-12649 <= MISP 2.4.92 - An issue was discovered in app/Controller/UsersController.php in MISP 2.4.92. An adversary can bypass the brute-force protection by using a PUT HTTP method instead of a POST HTTP method in the login part, because this protection was only covering POST requests.
  • CVE-2018-19908 <= MISP 2.4.98 - An issue was discovered in MISP 2.4.9x before 2.4.99. In app/Model/Event.php (the STIX 1 import code), an unescaped filename string is used to construct a shell command. This vulnerability can be abused by a malicious authenticated user to execute arbitrary commands by tweaking the original filename of the STIX import.
  • CVE-2019-9482 <= MISP 2.4.102 - In MISP 2.4.102, an authenticated user can view sightings that they should not be eligible for.

  • CVE-2019-12794 <= MISP 2.4.108 - An issue was discovered in MISP 2.4.108. Organization admins could reset credentials for site admins (organization admins have the inherent ability to reset passwords for all of their organization’s users).
  • CVE-2019-12868 <= MISP 2.4.109 - app/Model/Server.php in MISP 2.4.109 allows remote command execution by a super administrator because the PHP file_exists function is used with user-controlled entries, and phar:// URLs trigger deserialization.
  • CVE-2019-14286 <= MISP 2.4.111 - In app/webroot/js/event-graph.js in MISP 2.4.111, a stored XSS vulnerability exists in the event-graph view when a user toggles the event graph view. A malicious MISP event must be crafted in order to trigger the vulnerability.
  • CVE-2019-16202 <= MISP 2.4.114 - MISP before 2.4.115 allows privilege escalation in certain situations.
