Summary
Apache NiFi 2.0.0 through 2.10.0 allows creating, reading, and deleting Assets via REST API. The framework authorizes deletion based on the Parameter Context ID without verifying Asset ownership. Installations without different authorization levels across contexts are not affected. Upgrade to 2.11.0 fixes the issue.
Risk Assessment
Risk of unauthorized deletion of Assets belonging to other Parameter Contexts, potentially disrupting system operations.
Recommendation
Upgrade Apache NiFi to version 2.11.0 or later.
Original NVD description (English source)
Apache NiFi 2.0.0 through 2.10.0 support creating, reading, and deleting Assets associated with Parameter Contexts through the REST API. The framework authorizes asset deletion against the owning Parameter Context using the supplied Parameter Context Identifier and Asset Identifier. The framework performed authorized based on the supplied Parameter Context Identifier without verifying the requested Identifier against the stored Identifier. Apache NiFi installations that do not implement different levels of authorization across Parameter Contexts are not subject to this vulnerability, because the framework enforces write permissions as the security boundary. Upgrading to Apache NiFi 2.11.0 is the recommended mitigation, which verifies Parameter Context ownership of the requested Asset before deletion using the same strategy applied to Asset read operations.
