Name of the Vulnerable Software and Affected Versions
MISP core (affected versions not specified)
Description
Broken access-control flaws exist where authorization checks are performed against incorrect entities or ownership and editability checks are missing on write paths. This allows a lower-privileged authenticated user with specific feature permissions to authorize one object while mutating another, or modify objects that are visible but not editable by their organization. Affected areas include
- Event Reports tag removal: The route-authorized report may differ from the report ID used for tag detachment, allowing cross-organization tag removal.
- Collection Elements bulk deletion: Authorization occurs against a collection whose ID matches the collection-element row ID instead of the actual parent collection, allowing deletion of elements from collections not owned by the user.
- Analyst Data capture/update: Nested updates may overwrite records without the
canEditAnalystData()ownership check, enabling cross-organization overwrites. - Template Elements editing: Authorization occurs against a template whose ID matches the template-element ID instead of the parent template, allowing unauthorized edits to other organizations' template elements.
- Decaying Model editing and mappings: Write paths load models using view-scope access without verifying edit ownership, allowing users to edit or remap visible models owned by other organizations.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
