CVE-2019-7609
RCE in Elastic Kibana ≤ 5.6.15
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2019-7609 is a critical-severity Code Injection (CWE-94) vulnerability in Elastic Kibana. Its CVSS base score is 10.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Kibana versions before 5.6.15 and 6.6.1 contain an arbitrary code execution flaw in the Timelion visualizer, tracked as CVE-2019-7609 with CWE-94. The issue permits an attacker to submit a request that attempts to execute JavaScript code within the affected component, carrying a CVSS 3.1 score of 10.0 reflecting network attack vector, low complexity, and no required privileges or user interaction.
An attacker with access to the Timelion application can exploit the flaw to run arbitrary commands on the underlying host using the permissions of the Kibana process. This can result in full compromise of confidentiality, integrity, and availability on the affected system.
Elastic security advisories and corresponding Red Hat errata direct users to apply the updates released in versions 5.6.15 and 6.6.1. Additional guidance appears in Elastic's coordinated disclosure notice and community security announcement.
Public references include a detailed exploit description on PacketStorm, confirming the prototype-pollution vector that leads to remote code execution.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
