Summary
MISP is an open source threat intelligence and sharing platform. Prior to version 2.5.37, MISP Collections did not enforce RFC 4122 UUID validation, allowing users to submit malformed UUID values, potentially leading to data integrity issues.
Risk Assessment
The ability to introduce malformed UUIDs may lead to data integrity problems and unexpected application behavior, which can impact the organization's security.
Recommendation
It is recommended to upgrade MISP to version 2.5.37 or later to ensure proper UUID validation and minimize the risk associated with this vulnerability.
Original NVD description (English source)
MISP is an open source threat intelligence and sharing platform. Prior to 2.5.37, MISP Collections did not enforce RFC 4122 UUID validation on the uuid field. As a result, a user able to create or modify Collection records could submit malformed UUID values, potentially causing integrity issues or unexpected behaviour in code paths that assume Collection UUIDs are valid identifiers. This vulnerability is fixed in 2.5.37.
