Overview<\/strong><\/p>\n

The CVE-2025-57295 is a significant vulnerability that affects H3C devices running firmware version NX15V100R015. This vulnerability is particularly critical as it allows unauthorized access to these devices due to insecure default credentials, potentially leading to severe security breaches. As it opens the gate to unauthorized root-level access to the device, this vulnerability could lead<\/a> to privilege escalation, information disclosure, or arbitrary code execution, posing a considerable risk to the integrity and confidentiality of the system data.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-57295
\nSeverity: High (CVSS Score: 8.0)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Unauthorized root-level access to the device, privilege escalation<\/a>, information disclosure, or arbitrary code execution<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

H3C Devices<\/a> | NX15V100R015<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of the lack of password<\/a> for the root user account and the use of a default password for the H3C user account on the mentioned devices. Both these credentials are stored in the \/etc\/shadow file. An attacker with network access can exploit these credentials<\/a> to gain unauthorized root-level access to the device via the administrative interface or other network services. This unauthorized access can potentially lead to privilege escalation<\/a>, information disclosure, or arbitrary code execution.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a conceptual example of how an attacker might exploit this vulnerability via<\/a> SSH:<\/p>\n

ssh root@target_device_ip\n# No password required\nssh H3C@target_device_ip\n# Use \"admin\" as password<\/code><\/pre>\n
Once logged in, the attacker has root-level access to the device and can execute arbitrary<\/a> commands, access sensitive information or escalate their privileges further.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. As a temporary mitigation, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious network activities. Additionally, users are also advised to change the default password<\/a> for the H3C user account and set a strong password for the root user account.<\/p>\n","protected":false},"excerpt":{"rendered":"
