CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/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-2023-30349 is a critical-severity Code Injection (CWE-94) vulnerability in Jflyfox Jfinal Cms. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 25% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV 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.
JFinal CMS version 5.1.0 contains a remote code execution vulnerability in the ActionEnter function. The flaw is tracked as CVE-2023-30349 with a CVSS 3.1 base score of 9.8 and is associated with CWE-94 code injection. It permits unauthenticated attackers to supply crafted input that results in arbitrary code execution on the server.
An attacker with network access can invoke the affected function without credentials or user interaction, achieving full confidentiality, integrity, and availability impact on the underlying host. Successful exploitation grants the ability to run operating-system commands, read or modify application data, and potentially pivot within the environment.
EPSS probability for the CVE reached a peak of 0.2089 before receding to the current value of 0.0413, indicating a period of elevated exploitation interest after disclosure. The two referenced GitHub issues contain the original discovery report but do not detail vendor patches or configuration work-arounds.

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.
