CVE-2022-47879
Published: 12 May 2023
Summary
CVE-2022-47879 is a high-severity Code Injection (CWE-94) vulnerability in Jedox Jedox. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 8.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-47879 is a remote code execution vulnerability in the /be/rpc.php endpoint of Jedox versions up to and including 22.5. The flaw permits remote authenticated users to load arbitrary PHP classes from the rtn directory and invoke their methods, which maps to CWE-94 and carries a CVSS 3.1 score of 7.5 reflecting high impact on confidentiality, integrity, and availability under network attack with low attack complexity once authentication is obtained.
An attacker who already possesses valid credentials can therefore execute arbitrary code on the server by supplying crafted class and method references, achieving full compromise of the affected Jedox installation without further user interaction.
Vendor statements and the referenced disclosure documents indicate that the issue was fixed in Jedox 23.2; installations running that release or later are not affected, and users are advised to upgrade promptly. The associated EPSS score reached a peak of 0.1025 before receding to its current value of 0.0683, indicating modest post-disclosure interest that has since declined.

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.
