How the Exploit Works

The exploit works by taking advantage of a stack-based buffer overflow vulnerability in the strcpy function of the /goform/SetFirewallCfg file in the Tenda AC20 router firmware. An attacker can maliciously manipulate the argument ‘firewallEn’ to overflow the buffer, which can potentially lead to arbitrary code execution. This means that the attacker can perform any operation on the system, leading to a complete system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This example assumes the attacker sends a malicious HTTP POST request to the vulnerable endpoint:

POST /goform/SetFirewallCfg HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
firewallEn=1&buffer=[Insert malicious payload here]

In this example, ‘[Insert malicious payload here] would be replaced with a payload designed to overflow the buffer, potentially leading to arbitrary code execution.

Mitigation

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy, helping to identify and block potential exploit attempts.

Affected Products

Product | Affected Versions

Grav CMS | v1.7.48

How the Exploit Works

The exploit takes advantage of a lack of proper file validation within the /admin/tools/direct-install interface of the Grav CMS. An attacker with admin privileges can upload a malicious plugin to this interface. Once uploaded, the plugin is automatically extracted and loaded, which is where the vulnerability lies. This process allows the execution of arbitrary PHP code within the server environment and the potential for reverse shell access, enabling the attacker to perform unauthorized operations on the server.

Conceptual Example Code

Below is a conceptual example of an HTTP request that could be used to exploit this vulnerability:

POST /admin/tools/direct-install HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="plugin"; filename="malicious_plugin.zip"
Content-Type: application/zip
(Contents of malicious_plugin.zip)
------WebKitFormBoundary7MA4YWxkTrZu0gW

In this example, a malicious plugin is uploaded as a zip file to the /admin/tools/direct-install endpoint. Once uploaded and extracted, the malicious PHP code within the plugin would be executed, resulting in a successful exploit of the vulnerability.

Mitigation Guidance

The best way to mitigate this vulnerability is to apply the vendor-provided patch as soon as possible. If this is not immediately feasible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure to block potential exploit attempts. However, these should only be seen as temporary solutions, and patching the system should be the priority.

Affected Products

Product | Affected Versions

Vedo Suite | 2024.17

How the Exploit Works

An attacker, once authenticated, can exploit this vulnerability by sending a specially crafted request to the ‘uploadPreviews()’ function in ‘/api_vedo/colorways_preview. The function does not properly validate the uploaded file, allowing the attacker to upload files to arbitrary locations within the server’s filesystem. This functionality can be misused to upload malicious scripts or executables, which, when executed, can lead to remote code execution.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability:

POST /api_vedo/colorways_preview HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW

Vulnerability Summary

CVE ID: CVE-2025-54886
Severity: High (CVSS: 8.4)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

skops Python library | 0.12.0 and below

How the Exploit Works

The root cause of the vulnerability lies in the Card.get_model function of the skops library. While the function supports secure loading for .skops models, it falls back to the joblib loader for non-.zip file formats without any warning. This is problematic as joblib allows arbitrary code execution during loading, bypassing the security measures in place. Consequently, an attacker can potentially execute malicious code by merely providing a non-.zip file for loading.

Conceptual Example Code

This is a conceptual example of how the vulnerability might be exploited. An attacker could craft a malicious non-.zip file that contains a payload leading to arbitrary code execution when loaded by the joblib loader.

from skops import Card
# Malicious payload embedded in a non-zip file
malicious_file = 'malicious.pkl'
# Loading the malicious file using the Card.get_model function
model = Card.get_model(malicious_file)

In this example, `malicious.pkl` is a non-zip file containing a crafted payload. When the `Card.get_model` function is used to load this file, it falls back to joblib’s loader, executing the malicious code embedded in the file.

Mitigation

Users are strongly advised to upgrade the skops library to version 0.13.0 or later, where the issue has been fixed. If upgrading is not possible, a temporary mitigation would be to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block suspicious file loading activities.

Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Eventin WordPress Plugin |

How the Exploit Works

The exploit takes advantage of a flaw in the ‘Eventin\Speaker\Api\SpeakerController::update_item’ function. The function does not validate a user’s identity or capability adequately before updating their details, like their email. This flaw allows an unauthenticated attacker with contributor-level and above permissions to change arbitrary user email addresses, including administrators. Once the attacker has changed the email address, they can then reset the user’s password. This password reset enables the attacker to gain access to the user’s account, leading to a potential system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of an HTTP request that might exploit this vulnerability:

POST /wp-json/eventin/v1/speakers/<id> HTTP/1.1
Host: vulnerable-website.com
Content-Type: application/json
{
"email": "attacker@email.com"
}

In this example, the attacker replaces the `` with the ID of the target user’s account and `attacker@email.com` with the attacker’s email address. As a result, the attacker can reset the password of the target user’s account, effectively taking over the account.
It’s important to note that this is a conceptual example and real-world attacks could be more sophisticated or combined with other attack vectors. Nevertheless, this example demonstrates the critical nature of the vulnerability and the importance of applying the available patches or setting up WAF/IDS for temporary mitigation.
