How the Exploit Works

The exploit takes advantage of the telnet service (telnetd) that is initiated by default at boot via the initialization script /etc/init.d/eth.sh. This insecure permission setting can allow a remote attacker to connect to the device’s shell over the network, potentially without any authentication if default or weak credentials are present.

Conceptual Example Code

This is a conceptual example of how an attacker could potentially take advantage of this vulnerability using a telnet client:

$ telnet target_device_ip
Trying target_device_ip...
Connected to target_device_ip.
Escape character is '^]'.
login: admin
password: admin
# Successful login without any authentication due to insecure permission

Please note that this is a conceptual representation and that actual exploitation would depend on many factors including network configuration, firewall settings, and the presence of default or weak credentials.

Vulnerability Summary

CVE ID: CVE-2025-6742
Severity: High (7.5 CVSS)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

SureForms – Drag and Drop Form Builder for WordPress| Up to and including 1.7.3

How the Exploit Works

The SureForms plugin has a flaw in the delete_entry_files() function. It uses file_exists() without placing any restriction on the path provided, making the plugin vulnerable to PHP Object Injection. This vulnerability can be exploited by unauthenticated users. However, the impact of this vulnerability relies on the presence of another plugin or theme containing a POP chain. If such a plugin or theme is installed, the attacker might be able to delete arbitrary files, retrieve sensitive data, or execute code based on the POP chain.

Conceptual Example Code

Here’s a conceptual example of a malicious request that could exploit this vulnerability:

POST /wp-admin/admin-ajax.php?action=sureforms_delete_entry_files HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"path": "../../../../../../../var/www/html/wp-config.php"
}

In this scenario, the path is manipulated to point to a sensitive file (wp-config.php), which contains database connection details. If a POP chain is present, this file could be deleted or its contents leaked, potentially leading to a system compromise.

Mitigation

Users are urged to apply the vendor patch as soon as it becomes available. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used to help detect and prevent exploitation attempts.

Affected Products

Product | Affected Versions

IBM InfoSphere Data Replication VSAM for z/OS Remote Source | 11.4

How the Exploit Works

The exploit takes advantage of an error handling mechanism in the log reading service of the affected product. An attacker can send an invalid HTTP request to this service, which fails to handle the request correctly and crashes, resulting in a denial of service. This could potentially compromise the system or lead to data leakage.

Conceptual Example Code

Given the nature of the exploit, an attacker might use a malformed HTTP request to trigger the vulnerability. Here is a conceptual example of what such a request might look like:

GET /log/invalid_endpoint HTTP/1.1
Host: target.example.com

This request aims at a non-existing endpoint (‘/log/invalid_endpoint’) in the log reading service. The service, unable to handle this invalid request properly, could crash and cause a denial of service.

Mitigation

Users are advised to apply the vendor-supplied patch to fix this vulnerability. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to block malformed HTTP requests to the log reading service, preventing the exploit from triggering the vulnerability.

Affected Products

Product | Affected Versions

MCP Server Kubernetes | Versions prior to 2.5.0

How the Exploit Works

The vulnerability is caused by unsanitized input parameters within a call to child_process.execSync in the MCP Server Kubernetes. This exploit takes advantage of the server’s lack of proper input sanitization to inject arbitrary system commands.

Conceptual Example Code

A conceptual example of how the vulnerability might be exploited is as follows:

$ curl -X POST -H "Content-Type: application/json" -d '{"command": "; arbitrary_system_command ;"}' http://target.example.com/vulnerable/endpoint

In this example, the attacker sends a POST request to the vulnerable endpoint with a JSON payload containing an arbitrary system command. The command is injected into the system via the unsanitized `command` field, which is processed by `child_process.execSync`, leading to the execution of the injected command.

Mitigation

The recommended mitigation method is to apply the vendor patch, namely, the upgrade to version 2.5.0 which contains a fix for the vulnerability. As a temporary mitigation, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help to filter out malicious payloads.

Affected Products

Product | Affected Versions

node-code-sandbox-mcp | < 1.3.0 How the Exploit Works

The vulnerability exists due to the unsanitized use of input parameters within a call to child_process.execSync. This allows an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process’s privileges on the host machine, bypassing the sandbox protection of running code inside docker.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability:

// Attacker uses unsanitized input to pass malicious command
var payload = "`touch /tmp/arbitrary-file`";
// The unsanitized input is passed to child_process.execSync
require('child_process').execSync(payload);

In this example, if the payload is executed, an arbitrary file would be created in the /tmp directory, demonstrating the ability to execute arbitrary commands.
