Overview
A notable cybersecurity vulnerability has been identified in the H3C Device R365V300R004. This flaw, identified as CVE-2025-57577, allows a remote attacker to execute arbitrary code via the device’s default password. This vulnerability is of high concern due to its potential to compromise systems or lead to data leakage. It primarily affects organizations using H3C devices without changing their default password. The severity of this vulnerability is underscored by its CVSS Severity Score of 8.0, highlighting the necessity for immediate action.

How the Exploit Works
This vulnerability exploits the use of default passwords in H3C devices. An attacker can remotely connect to the device using the default password, circumventing any authentication measures. Once connected, they can execute arbitrary code on the device, potentially compromising the system or leading to data leakage. This is possible if the administrator has neglected to change the default credentials upon first use.
Conceptual Example Code
The following is a conceptual example of how the exploit might be executed. The attacker would send a network request to the device, using the default credentials and including their arbitrary code in the payload.
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Basic Base64(‘admin:default_password’)
{
"malicious_payload": "..."
}Mitigation Guidance
To mitigate this vulnerability, it is highly recommended that the vendor’s patch is applied as soon as possible. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these measures do not replace the necessity of changing the default password. The vendor underscores that their product lines enforce or clearly prompt users to change any initial credentials upon first use. Failure to do so may result in system compromise.
