CVE-2025-25211
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-25211 is a critical-severity Weak Password Requirements (CWE-521) vulnerability in Jvn (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked in the top 45% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to 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-2025-25211 is a weak password requirements vulnerability, classified under CWE-521, affecting all versions of the CHOCO TEI WATCHER mini (IB-MCT001) device. Published on March 31, 2025, it carries 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), indicating critical severity due to its network accessibility, low attack complexity, and lack of prerequisites for exploitation.
The vulnerability enables remote attackers with no privileges or user interaction to perform brute-force attacks against weak password policies, resulting in unauthorized access and login to the device. Exploitation could lead to high-impact compromise of confidentiality, integrity, and availability, such as unauthorized control over the monitoring functions of the affected hardware.
Advisories from JVN (JVNVU#91154745), CISA (ICS-A-25-084-04), vendor Inaba (chocomini_vulnerability.pdf), and Nozomi Networks detail mitigation strategies, with the latter noting unpatched vulnerabilities in production-line cameras that may enable remote surveillance and hinder stoppage recording. Security practitioners should consult these references for patch availability and hardening guidance.
