Short explanation
A uniqueItems keyword validation flaw in Eclipse Vert.x allows remote unauthenticated attackers to cause a denial of service.
This vulnerability enables attackers to submit moderately-sized JSON arrays, consuming disproportionate CPU time and leading to service disruptions.
What should be done?
- Follow vendor advisories
- Update affected modules
- Limit JSON array sizes
Chain of evidence and sources
Eclipse Vert.x sürümlerinde uniqueItems anahtar kelime doğrulaması kısa devre veya boyut sınırı olmaksızın O(n²) ikili karşılaştırma döngüsü kullanır.
Uzaktan kimlik doğrulaması yapılmamış bir saldırgan, aşırı CPU süresi tüketerek denial of service durumuna yol açan orta büyüklükte bir JSON dizisi sunabilir.
Etkilenen bileşen io.vertx:vertx-json-schema olup, buna bağlı olan io.vertx:vertx-web-openapi-router, io.vertx:vertx-web-validation ve io.vertx:vertx-openapi modülleri de etkilenmektedir.
Show the technical text from the sources
In Eclipse Vert.x versions [4.0.0, 4.5.34] or [5.0.0,5.0.12] or [5.1.0,5.1.9] or [5.2.0, 5.2.0], the uniqueItems keyword validation uses an O(n²) pairwise comparison loop with no short-circuit or size limit. A remote unauthenticated attacker can submit a moderately-sized JSON array that consumes disproportionate CPU time, leading to denial of service. The impacted component is io.vertx:vertx-json-schema. The following Vert.x modules depend on vertx-json-schema and are also affected: io.vertx:vertx-web-openapi-router io.vertx:vertx-web-validation io.vertx:vertx-openapi
