Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NSummary
CVE-2025-24517 is a high-severity Use of Client-Side Authentication (CWE-603) vulnerability in Jvn (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) 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.
CVE-2025-24517 is a client-side authentication flaw (CWE-603) affecting all versions of CHOCO TEI WATCHER mini (IB-MCT001). The vulnerability permits unauthenticated remote access to the device's login password, resulting in a CVSS 3.1 score of 7.5 with network attack vector, low complexity, and high confidentiality impact.
An unauthenticated attacker can exploit the issue over the network to retrieve the product login credentials without any user interaction or prior authentication, thereby gaining the ability to log into the device and access its functions.
Vendor and government advisories, including those from Inaba Denki Sangyo and CISA (ICSA-25-084-04), direct users to the manufacturer's mitigation guidance published in the associated PDF; JVN also references the same vendor document for resolution steps.
EPSS for the CVE rose from a low baseline of 0.0060 to a peak of 0.0107, indicating increased exploitation interest after disclosure.
