CVE-2018-14667 is a critical-severity Code Injection (CWE-94) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.6% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.
The RichFaces Framework versions 3.x through 3.3.4 contain an Expression Language injection vulnerability in the UserResource component. The flaw resides in org.ajax4jsf.resource.UserResource$UriData and is tracked as CWE-94, allowing code injection through improper handling of serialized data. It received a CVSS 3.1 score of 9.8, reflecting network-accessible attack conditions with no required authentication or user interaction.
A remote unauthenticated attacker can supply a crafted chain of Java serialized objects to the UserResource endpoint, resulting in arbitrary code execution on the server. The attack requires only the ability to reach the affected RichFaces application and does not depend on any authenticated session or special privileges.
Red Hat has published errata RHSA-2018:3517 and RHSA-2018:3518 that address the issue in supported products. Public references also describe the Richsploit exploitation toolkit and related disclosure activity from 2020, indicating that working proof-of-concept code has been made available.

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.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
