Vulnerability from fkie_nvd - Published: 2026-09-02 11:17 - Updated: 2026-09-03 16:41

Severity

7.6 (High) - CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N

Summary

In Eclipse Ditto versions [1.3.0, 3.9.6], the ImplicitThingCreationMessageMapper of the connectivity service builds a CreateThing command by substituting placeholder values (e.g. {{ header:device_id }}) resolved from inbound message headers into a pre-configured JSON "thing" template as raw, un-escaped strings, and then parses the resulting string as JSON. Because the placeholder engine performs no JSON escaping and is unaware of the surrounding JSON string context, a resolved value containing a double-quote character can break out of its string and inject additional JSON structure. When a connection is configured to use this mapper with a template that reflects a header whose value a publishing device can control (for example an MQTT 5 user property, an AMQP 1.0 application property, or a Kafka record header), an attacker able to publish on that connection can inject an inline _policy object. The inline policy overrides the administrator-configured policyId, letting the attacker assign an arbitrary access-control policy to the newly created digital twin — gaining full read/write access to it and potentially revoking the legitimate owner's access, with no administrator interaction. Exploitation requires all of the following: the connection uses the (non-default) ImplicitThingCreation mapper; its template reflects an attacker-controllable header; and, for the policy-override impact, the connection's authorization subjects are permitted to create policies (the default). Deployments that restrict the connection's subjects to thing creation only via the entity-creation configuration are not affected by the policy-override impact.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
