Published: 27 April 2023
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, ranked in the top 11.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
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.

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.
