H3C Magic M Device | M2V100R006

How the Exploit Works

The exploit takes advantage of a default password vulnerability in the H3C Magic M Device M2V100R006. An attacker can remotely connect to the device using the default password, bypassing any authentication mechanisms in place. This allows the attacker to gain unauthorized access to the system. Once access is gained, the attacker is able to execute arbitrary code on the system, leading to potential system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit the vulnerability using a simple SSH command:

ssh root@target_ip -p port_number
# The attacker then enters the default password when prompted

Once logged in, the attacker can execute arbitrary commands, potentially compromising the system or exfiltrating sensitive data.

Mitigation and Workarounds

To mitigate this vulnerability, users are advised to apply the vendor-supplied patch as soon as it becomes available. In the meantime, users can apply some temporary mitigation measures such as using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block suspicious activities.
Moreover, users should change the default password of the device to a strong, unique password to prevent unauthorized access. Regularly updating and patching your systems, along with following security best practices, can greatly reduce the risk of exploitation.

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.

H3C Device | R365V300R004

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.

Overview

This blog post aims to shed light on a significant security vulnerability tagged as CVE-2025-9693, which affects the User Meta – User Profile Builder and User management plugin for WordPress. The vulnerability could potentially allow an attacker with Subscriber-level access to delete arbitrary files on the server. This vulnerability is crucial as it can lead to remote code execution if a critical file (e.g., wp-config.php) is deleted. The potential system compromise or data leakage due to this vulnerability underscores its severity.

Vulnerability Summary

CVE ID: CVE-2025-9693
Severity: High (CVSS: 8.0)
Attack Vector: Network
Privileges Required: Low (Subscriber-level access)
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

User Meta – User Profile Builder and User management plugin | Up to and including 3.1.2

How the Exploit Works

The vulnerability stems from insufficient file path validation in the postInsertUserProcess function of the User Meta – User Profile Builder and User management plugin for WordPress. An attacker with Subscriber-level access can exploit this vulnerability by sending a specially crafted request to the server that manipulates file paths to point to arbitrary files on the server. This allows the attacker to delete any file of their choosing, with potential targets being critical system files whose deletion could lead to remote code execution.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited. This is a simplified example and does not represent actual code:

POST /user_meta/user_profile_builder/delete_file HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "filepath": "/absolute/path/to/wp-config.php" }

In this example, the attacker is sending a POST request to the delete_file endpoint of the User Meta – User Profile Builder plugin with a JSON payload specifying the absolute path to the wp-config.php file. If the endpoint is vulnerable and does not validate the filepath correctly, it may process this request and delete the specified file, leading to possible remote code execution.

Mitigation

Users of the affected plugin are strongly encouraged to apply the vendor-supplied patch as soon as possible. If a patch cannot be applied immediately, users should consider leveraging a web application firewall (WAF) or an intrusion detection system (IDS) as a temporary mitigation measure. These systems can be configured to block or alert on suspicious requests that target the vulnerable endpoint.
