CyberRota Analysis
AI-GeneratedMISP is vulnerable due to improper input validation in its ORM save path, allowing authenticated users with basic write permissions to exploit the system by embedding malicious nested blocks in their requests. This can lead to cross-tenant data integrity issues, enabling attackers to overwrite or delete data associated with other organizations or events without appropriate access rights. Organizations using affected versions prior to 2.5.48 should prioritize patching to mitigate the risk of unauthorized data manipulation.

Original NVD Description
MISP contains an improper input validation vulnerability in its ORM save path. When a user submits data through various endpoints (attribute add/edit, event edit, free-text import, sighting capture, shadow attribute proposal, event report creation, object reference add, user admin edit), the application sanitizes the flat record by stripping the primary key and pinning the event_id or object_id to the caller's context. However, the underlying ORM's set() method gives priority to a nested key whose name matches the model alias and discards the outer scalar fields. An authenticated user with basic write permissions can exploit this by embedding a nested block under the model alias key inside their request. The sanitization logic (id removal, event_id pinning) is applied to the outer record, but the ORM binds to the inner record instead, which carries an attacker-chosen id and event_id. This allows the attacker to overwrite, re-parent, or soft-delete rows belonging to other organizations or events they have no read access to. Impact: - Cross-tenant data integrity compromise (attribute values rewritten, objects re-parented to attacker events, rows soft-deleted) - Affects multiple entity types: Attribute, Object, EventReport, Sighting, AttributeTag, ShadowAttribute - Requires only a low-privilege authenticated account with perm_add Affected versions: <2.5.48
