Detailsinfo

A vulnerability was found in MISP up to 2.5.47. It has been rated as problematic. Affected by this issue is an unknown code block of the component Attribute Search. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. Impacted is confidentiality. CVE summarizes:

MISP contains an improper access control vulnerability in its attribute search and paginated attribute view endpoints. When a user queries for soft-deleted attributes (e.g., via the deleted-attributes search or the paginated attribute listing), the application returned soft-deleted attributes belonging to events owned by other organizations to any authenticated user who had visibility of the event. The event detail view correctly restricted soft-deleted attribute visibility to the owning organization and sync-permission users, but the attribute search and paginated view code paths lacked this restriction. Preconditions: - An authenticated MISP user with at least read access to an event owned by another organization. - The user issues a query for deleted attributes (search or paginated view with the deleted filter). Impact: - Confidentiality: Soft-deleted threat intelligence attributes (e.g., IOCs, indicators, context) from other organizations are disclosed to unauthorized users. This may expose sensitive intelligence that the owning organization intended to remove from general visibility. Affected versions: MISP versions prior to v2.5.48.
