Summary

CVE-2025-2398 is a high-severity Use of Default Credentials (CWE-1392) vulnerability. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked at the 43th 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 CM-6 (Configuration Settings) and IA-5 (Authenticator Management) — 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-2025-2398 is a vulnerability in the CLI su Command Handler of China Mobile P22g-CIac, ZXWT-MIG-P4G4V, ZXWT-MIG-P8G8V, GT3200-4G4P, and GT3200-8G8P devices running firmware up to version 20250305. Rated as critical with a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and mapped to CWE-1392 (Use of Default Credentials), the flaw allows manipulation leading to exploitation of default credentials.

The vulnerability can be exploited remotely by attackers who possess high privileges on the affected system. Successful exploitation enables high confidentiality, integrity, and availability impacts, facilitating unauthorized access such as execution of telnet commands, as detailed in public disclosures.

Advisories from VulDB and GitHub vulnerability reports indicate that the vendor was contacted early regarding the issue but provided no response. No patches or official mitigations are mentioned, and the exploit has been publicly disclosed, including proof-of-concept details in repositories like https://github.com/Fizz-L/Vulnerability-report/blob/main/Unauthorized%20access%20to%20execute%20the%20telnet%20command.md and VulDB entries at https://vuldb.com/?ctiid.299897 and https://vuldb.com/?id.299897.

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure configuration settings establish baselines that prohibit default credentials on system components.

IA-5 Authenticator Management good match

Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.

RA-5 Vulnerability Monitoring and Scanning good match

Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.

AC-2 Account Management partial match

Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.

PR.AA-01 mostly match
prevents

Credential management processes directly require replacing or disabling default passwords and keys.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.9 Configuration management mostly match
prevents

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
