DescriptionCVE.org

A security flaw has been discovered in provectus kafka-ui up to 0.7.2. The affected element is the function executeSmartFilterTest of the file kafka-ui-api/src/main/java/com/provectus/kafka/ui/controller/MessagesController.java of the component Groovy Code Handler. The manipulation results in code injection. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Remote code injection in provectus kafka-ui up to version 0.7.2 allows a low-privileged authenticated attacker to execute arbitrary Groovy code on the server via the smart filter test endpoint. The vulnerability resides in the executeSmartFilterTest function of MessagesController.java, where user-supplied Groovy expressions are evaluated without adequate sandboxing or restriction. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated session in kafka-ui with access to the message browsing or smart filter test functionality (CVSS PR:L - low privilege). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) scores 5.3 and reflects low privileges required with limited impact metrics - likely a conservative vendor or reporter assessment. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated kafka-ui user with any level of access navigates to the smart filter test interface and submits a crafted Groovy payload - for example, invoking Runtime.exec() - targeting the executeSmartFilterTest endpoint. Because the Groovy engine runs without a restrictive sandbox, the payload executes on the server with the privileges of the kafka-ui process, potentially granting shell access, credential theft, or lateral movement within the Kafka infrastructure. …
Remediation No vendor-released patch has been identified at time of analysis; the project maintainers have not responded to the disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.
