H3C devices running firmware version NX15V100R015 are vulnerable to unauthorized access due to insecure default credentials. The root user account has no password set, and the H3C user account uses the default password admin, both stored in the /etc/shadow file. Attackers with network access can exploit these credentials to gain unauthorized root-level access to the device via the administrative interface or other network services, potentially leading to privilege escalation, information disclosure, or arbitrary code execution.
Weakness
The product does not require that users should have strong passwords.

Potential Mitigations
A product’s design should require adherance to an appropriate password policy. Specific password requirements depend strongly on contextual factors, but it is recommended to contain the following attributes:
Depending on the threat model, the password policy may include several additional attributes.
See NIST 800-63B [REF-1053] for further information on password requirements.
