Conceptual Example Code

While the exact code to exploit this vulnerability is not available, a conceptual example would involve an attacker gaining access to the build VM and then modifying the image during the build process. The pseudocode might look something like this:

# Gain root access to the build VM
sudo su
# Navigate to the location of the image being built
cd /path/to/image
# Modify the image with malicious code
echo 'malicious code' >> image_file

This example is highly conceptual and the actual exploit could be more complex, requiring a deep understanding of the Kubernetes Image Builder’s internals.

Mitigation

Users are advised to apply the vendor patch as soon as it becomes available. Until then, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as temporary mitigation.

Vulnerability Summary

CVE ID: CVE-2025-7664
Severity: High – 7.5 (CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

AL Pack for WordPress | All versions up to, and including, 1.0.2

How the Exploit Works

The vulnerability stems from a missing capability check on the check_activate_permission() permission callback for the /wp-json/presslearn/v1/activate REST API endpoint in the AL Pack plugin for WordPress. The callback reads the client-supplied Origin header and, after parsing, allows the request if it matches one of the trusted domains, without ever verifying user authentication, capabilities, or nonce tokens. As a result, unauthenticated attackers can activate premium features by simply spoofing the Origin header.

Conceptual Example Code

Here’s a conceptual HTTP request that could potentially exploit this vulnerability:

POST /wp-json/presslearn/v1/activate HTTP/1.1
Host: target.example.com
Origin: trusted.example.com
Content-Type: application/json
{ "premium_features": "activate" }

In this example, the attacker spoofs the Origin header to match a trusted domain, thereby bypassing the permission check and activating the premium features.

Recommended Mitigation Steps

To mitigate this vulnerability, it’s recommended to apply the vendor patch. In its absence, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as a temporary solution. Regularly updating and patching software is an essential part of maintaining an effective security posture.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise, potential data leakage

Affected Products

Product | Affected Versions

School Management System for WordPress Plugin | Up to and including 93.2.0

How the Exploit Works

The vulnerability arises due to the plugin’s insufficient escaping on user-supplied parameters and lack of adequate preparation on existing SQL queries. This allows unauthenticated attackers to append additional SQL queries into pre-existing ones, exploiting the weakness to extract sensitive information from the database.

Conceptual Example Code

Below is a conceptual example of how the vulnerability could be exploited:

POST /wp-admin/admin-ajax.php?action=smgt_add_subject HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
subject_name="test"; subject_code="test123" UNION ALL SELECT CONCAT(user_login,':',user_pass) FROM wp_users--

In this example, a malicious SQL command is injected into the ‘subject_name’ parameter, which gets executed as part of the original SQL query. The ‘UNION ALL SELECT’ statement allows the attacker to combine the results of the original query with details from the WordPress users’ table, potentially exposing sensitive user credentials.

Vulnerability Summary

CVE ID: CVE-2025-6025
Severity: High (7.5 CVSS)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Unauthorized manipulation of order values, potential system compromise, or data leakage

Affected Products

Product | Affected Versions

Order Tip for WooCommerce Plugin for WordPress | All versions up to and including 1.5.4

How the Exploit Works

The exploit takes advantage of the lack of server-side validation on the `data-tip` attribute. A malicious actor can manipulate the tip amount for an order, applying an excessive or even negative amount. This manipulation can result in unauthorized discounts up to free orders depending on the value submitted by the attacker. Since the vulnerability does not require authentication, it can be exploited by anyone who can interact with the network.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited:

POST /checkout HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"order": {
"items": [...],
"payment": {
"method": "credit_card",
...
},
"tip": {
"data-tip": "-10000"
}
}
}

In this example, the attacker is placing an order and setting a negative tip value (`”data-tip”: “-10000″`). Since there’s no server-side validation, the application subtracts this tip from the total order amount, effectively giving the attacker a large discount on their order.

Mitigation Measures

To mitigate the risk posed by this vulnerability, users of the affected plugin are advised to apply the vendor patch as soon as it becomes available. In the meantime, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation strategy, providing an additional layer of security against potential exploitation.
