Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 0.2% 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.

Craft CMS versions prior to 4.4.15 contain a code injection vulnerability tracked as CVE-2023-41892 and assigned CWE-94. The flaw carries a CVSS 3.1 score of 10.0 reflecting network attack vector, low complexity, no required privileges or user interaction, and changed scope with high impact on confidentiality and integrity plus partial availability loss. The affected component is the core Craft CMS application, and the issue was resolved in the 4.4.15 release.

Unauthenticated remote attackers can exploit the vulnerability to execute arbitrary code on the server. Successful exploitation grants full control over the application and underlying system, enabling data exfiltration, modification of content or configuration, and service disruption.

Public references, including the Craft CMS changelog and associated commits, direct administrators to upgrade installations to version 4.4.15 or newer. A proof-of-concept exploit demonstrating remote code execution against 4.4.14 has been published on Packet Storm.

The EPSS score remains near its peak of 0.9394 with a current value of 0.9382, indicating sustained exploitation interest after disclosure.

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.

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.

PR.PS-06 mostly match
blocks

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 none match
blocks

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.
