Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-36554 affects two specific firmware versions of Forever KidsWatch devices: the Call Me KW-50 running R36_YDR_A3PW_GM7S_V1.0_2019_07_15_16.19.24_cob_h and the Call Me KW-60 running R36CW_YDE_S4_A29_2_V1.0_2023.05.24_22.49.44_cob_b. The vulnerability enables a malicious user to obtain sensitive information about the device by sending an SMS message, which prompts the device to return that data. It is rated critical with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere). The CVE was published on 2025-02-06.
Any remote attacker can exploit this vulnerability without authentication, privileges, or user interaction by simply sending an SMS to the targeted device. Successful exploitation allows the attacker to retrieve sensitive device information, with high impacts on confidentiality, integrity, and availability as indicated by the CVSS vector.

V14.1.2
Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.
Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.
Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.
Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.

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.
Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.
Protecting environments from unauthorized logical access stops exposure of internal system details to outsiders.
Secure-development practices reduce the chance of code paths that leak sensitive system information.
