Summary
A security flaw was discovered in provectus kafka-ui up to 0.7.2 in the executeSmartFilterTest function of kafka-ui-api/src/main/java/com/provectus/kafka/ui/controller/MessagesController.java of the Groovy Code Handler component. The manipulation results in code injection. The attack can be launched remotely, and the exploit has been released.
Risk Assessment
A remote attacker can inject and execute arbitrary code in the application context, potentially leading to confidentiality, integrity, and availability breaches. The public exploit increases the risk of exploitation.
Recommendation
It is recommended to immediately update kafka-ui to a patched version if available. If not, restrict access to the application and monitor logs for suspicious activity.
