Summary
CVE-2024-21006 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Oracle Weblogic Server. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique System Service Discovery (T1007); ranked in the top 5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.
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 vulnerability CVE-2024-21006 resides in the Core component of Oracle WebLogic Server within Oracle Fusion Middleware. It affects supported versions 12.2.1.4.0 and 14.1.1.0.0 and is tracked under CWE-306. The flaw carries a CVSS 3.1 base score of 7.5 with a vector indicating network attack vector, low attack complexity, no required privileges or user interaction, and high confidentiality impact.
An unauthenticated attacker with network access via the T3 or IIOP protocols can exploit the issue to obtain unauthorized access to critical data or complete access to all Oracle WebLogic Server accessible data. No authentication or special conditions beyond network reachability are needed for successful exploitation.
Oracle’s April 2024 Critical Patch Update, published at https://www.oracle.com/security-alerts/cpuapr2024.html, addresses the vulnerability and directs administrators to apply the relevant patches for the affected WebLogic Server releases. The EPSS score stands at 0.8743 with an identical recorded peak, indicating sustained exploitation probability without a documented post-disclosure climb.

Mitigating Controls (NIST 800-53 r5) AI
Directly mandates unique identification and authentication of users before access to functions requiring identity.
Extends the same authentication requirement to non-organizational users accessing critical functionality.
Requires authentication of services before they can invoke or expose critical functions.
Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.
Access enforcement requires prior authentication before any authorization decision for critical functions.
Mitigating Controls (NIST CSF 2.0) AI
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.
Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.
Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.
Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.
Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
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.
Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
