Summary

CVE-2024-36553 is a high-severity Channel Accessible by Non-Endpoint (CWE-300) vulnerability in Diva Portal (inferred from references). Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 23th 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-3 (Device Identification and Authentication) and SC-11 (Trusted Path) — 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-2024-36553 is a Man-in-the-Middle (MITM) vulnerability affecting the Forever KidsWatch Call Me KW-50 device with firmware version R36_YDR_A3PW_GM7S_V1.0_2019_07_15_16.19.24_cob_h. Mapped to CWE-300 (Channel Accessible by Non-Endpoint), it earned a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N), highlighting its high severity due to network accessibility, low attack complexity, and significant impacts on confidentiality and integrity.

Any remote attacker without privileges can exploit this vulnerability over the network, provided they induce user interaction. Successful MITM interception enables high confidentiality and integrity violations, such as eavesdropping on or tampering with device communications, potentially leading to remote hijacking of the children's smartwatch.

A referenced research document details exploitation techniques for remotely hijacking children's smartwatches but provides no specific advisories, patches, or mitigation guidance.

Mitigating Controls (NIST 800-53 r5) AI

IA-3 mandates device identification and authentication prior to establishing communications, addressing the non-endpoint actor risk.

SC-23 enforces session authenticity protections that verify both endpoints and prevent channel manipulation by outsiders.

SC-11 provides an isolated trusted path that cryptographically or physically assures the identities of the two endpoints.

SC-8 directly requires cryptographic or equivalent mechanisms to protect the integrity (and confidentiality) of transmitted data, stopping non-endpoint interference.

AC-17 Remote Access partial match

AC-17 requires documented usage restrictions and secure configuration for remote access channels, reducing exposure to non-endpoint actors.

IA-2 requires unique identification and authentication of organizational users before any channel use, blocking unauthenticated endpoint access.
