Overview

Technical Description

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in misp allows Stored XSS.

This issue affects MISP before 2.5.37.

A stored cross-site scripting vulnerability exists in the template element attribute handling logic. The application accepted arbitrary values for the TemplateElementAttribute type and category fields without validating them against the known MISP attribute type and category definitions. An attacker with permission to create or modify template element attributes could store a crafted type value.

This affects the old templating (not more accessible in 2.5.37) engine from MISP which will be removed in 2.5.38

Remediation

Check the references section for vendor advisories and patches from misp-project. Update misp to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
