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 Identification and Authentication (Organizational Users) good match

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

IA-8 Identification and Authentication (Non-organizational Users) good match

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

IA-5 Authenticator Management good match

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

AC-3 Access Enforcement partial match

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

PR.AA-02 partial match

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

PR.AA-03 partial match
blocks

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