Summary

CVE-2024-43425 is a high-severity Code Injection (CWE-94) vulnerability in Moodle Moodle. Its CVSS base score is 8.1 (High).

Operationally, ranked in the top 0.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

A flaw in Moodle creates a remote code execution risk within calculated question types because of insufficient restrictions on code generation. The issue is tracked as CVE-2024-43425 and is associated with CWE-94; successful exploitation requires an attacker to possess the capability to add or update questions.

An attacker with network access who can supply crafted input to these question types may achieve arbitrary code execution on the server. The vulnerability carries a CVSS 3.1 score of 8.1, reflecting high impact on confidentiality, integrity, and availability under conditions of high attack complexity and no required user interaction.

Public advisories referenced in the Red Hat Bugzilla entry and the Moodle discussion forum indicate that additional server-side restrictions are needed to mitigate the code-injection exposure in calculated questions. The current EPSS score of 0.8892, with a recorded peak of 0.9008, reflects sustained exploitation interest following disclosure.

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.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
