Summary

CVE-2024-20153 is a high-severity Missing Critical Step in Authentication (CWE-304) vulnerability in Linuxfoundation Yocto. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-20153 is a vulnerability in the wlan STA component that allows attackers to trick a client device into connecting to an access point (AP) with a spoofed SSID. This flaw enables remote information disclosure without requiring additional execution privileges. The issue is tracked under Issue ID MSV-1598 and affects MediaTek products, as indicated by the associated patch IDs ALPS08990446 and ALPS09057442. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is associated with CWE-304 (Missing Critical Step).

The attack scenario involves a remote, unauthenticated attacker with network access who can exploit the vulnerability with low complexity and no user interaction required. By spoofing an SSID, the attacker can lure the client into connecting to a malicious AP, resulting in the disclosure of sensitive information from the affected device.

MediaTek's January 2025 Product Security Bulletin provides details on the vulnerability and recommends applying the patches ALPS08990446 or ALPS09057442 to mitigate the issue. Security practitioners should check the bulletin at https://corp.mediatek.com/product-security-bulletin/January-2025 for affected products and remediation guidance.

Mitigating Controls (NIST 800-53 r5) AI

IA-2 requires unique identification and authentication of users, directly mandating that all critical authentication steps be performed rather than skipped.

IA-8 requires unique identification and authentication of non-organizational users, ensuring the full authentication process is executed without missing steps.

IA-5 enforces proper authenticator lifecycle steps (verification, distribution, revocation) so that no required step in the authentication technique is omitted.

AC-3 enforces access decisions only after approved authentication has completed, making skipped authentication steps ineffective.

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.AA-03 mostly match
prevents

Requiring complete authentication (e.g., MFA, password policy) directly stops omission of critical steps in the auth process.

PR.AA-02 partial match
prevents

Proper identity proofing and credential binding prevents skipping enrollment steps that weaken authentication.

degrades

Mandates secure authentication mechanisms, explicitly addressing missing steps in authentication flows.

degrades

Directly requires secure management of authentication credentials and processes, preventing skipped critical steps.

prevents

Secure development lifecycle can catch missing auth steps during design, but does not directly enforce runtime authentication.

prevents

Application security requirements may specify complete auth flows, but the control itself is broader.

prevents

Secure coding practices can prevent missing auth steps, yet the control is not specific to authentication.

mitigates

Limits access based on proper authentication; incomplete auth weakens the restriction.

RHEL 7 (2 rules)
  • V-204425 The Red Hat Enterprise Linux operating system must be configured so that the SSH daemon does not allow authentication using an empty password. prevents CWE-304
