CVE-2025-5959: High Severity Type Confusion Vulnerability in Google Chrome
Overview

CVE-2025-5959 is a high-severity vulnerability that has been discovered in Google’s popular web browser, Chrome. This vulnerability is centered around the V8 JavaScript engine used by Chrome and can enable an attacker to execute arbitrary code inside a sandbox through a specifically crafted HTML page. This vulnerability is particularly concerning due to the widespread use of Google Chrome, making a large number of users potentially susceptible to this issue if left unaddressed.

Vulnerability Summary

CVE ID: CVE-2025-5959
Severity: High (8.8 CVSS Score)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: This vulnerability could result in a potential system compromise or data leakage

Affected Products

Product | Affected Versions

Google Chrome | Prior to 137.0.7151.103

How the Exploit Works

The vulnerability, a type confusion in V8, allows for the manipulation of the type of an object. Type confusion vulnerabilities occur when the program is tricked into treating an instance of one type as a different type. In the case of CVE-2025-5959, a remote attacker can send a maliciously crafted HTML page to a user. If the user opens this page in a vulnerable version of Chrome, the attacker can execute arbitrary code inside the browser’s sandbox environment.

Conceptual Example Code

The exploitation of this vulnerability would require a specifically crafted HTML page that exploits the type confusion in V8. The actual code would be highly dependent on the specific details of the V8 implementation and the target system, but conceptually, it would look something like this:
```
<html>
<script>
// Detailed JavaScript code that exploits the type confusion vulnerability in V8
var malicious_object = new ConfusableObject();
malicious_object.confuseType();
malicious_object.executeArbitraryCode();
</script>
<body>

</body>
</html>
```
In the example above, `ConfusableObject` is a placeholder for an actual object that can be used to exploit the type confusion vulnerability. The `confuseType` function would manipulate the internal state of the object to cause V8 to treat it as a different type, and the `executeArbitraryCode` function would take advantage of this type confusion to execute arbitrary code within the browser’s sandbox environment.

How the Exploit Works

The exploit takes advantage of a use-after-free vulnerability in Google Chrome’s Media component. In computer programming, ‘use after free’ refers to the attempt to access memory after it has been freed, which can cause a program to crash or, as in this case, can potentially allow the execution of arbitrary code.
An attacker can craft a malicious HTML page to trigger this vulnerability. Once a user opens this page in a vulnerable version of Chrome, the attacker can corrupt the heap memory. This could allow the attacker to execute arbitrary code within the context of the browser, potentially leading to full system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example of how a malicious HTML page might be crafted:
```
<!DOCTYPE html>
<html>
<body>
<script>
// Malicious JavaScript code that exploits the vulnerability
var buffer = new ArrayBuffer(100);
var dataview = new DataView(buffer);
dataview.setFloat32(0, 0.1); // This causes use-after-free
// More malicious code that uses the corruption to execute arbitrary commands
</script>
</body>
</html>
```
Please note that this is a simplified and conceptual example and the actual exploit might be much more complex and obfuscated.

Mitigation Guidance

How the Exploit Works

The exploit leverages the deserialization vulnerability in Microsoft Office SharePoint. Deserialization is the process of converting a stream of bytes back into a copy of the original object. In this case, an authorized attacker can insert malicious serialized data that, when deserialized, can execute arbitrary code. This is possible because SharePoint does not correctly validate or sanitize the serialized data it receives over the network.

Conceptual Example Code

The following is a conceptual representation of how the vulnerability might be exploited. This hypothetical HTTP request could be sent by an attacker to exploit the vulnerability:
```
POST /SharePoint/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/serialized-object
{ "serialized_object": "base64_encoded_malicious_object" }
```
In this case, `base64_encoded_malicious_object` represents a serialized object that contains malicious code. When the SharePoint server deserializes this object, it could potentially execute the embedded malicious code, leading to a system compromise or data leakage.

Mitigation Guidance

While Microsoft is likely to release a patch to address this vulnerability, organizations are advised to apply the vendor patch as soon as it is available. As an interim measure, organizations could employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent exploitation attempts. Other best practices include restricting network access to the SharePoint server and regularly updating all software components.

Affected Products

Product | Affected Versions

Microsoft SharePoint | All unpatched versions

How the Exploit Works

The vulnerability exists due to improper deserialization of untrusted data in Microsoft SharePoint. Deserialization is the process of converting data from a format suitable for storage or transmission back into an object. However, if an attacker can control the serialized data, they can manipulate it to execute arbitrary code when the data is deserialized.
In the case of CVE-2025-47163, an attacker with authorized access to the network could exploit this vulnerability by sending a specially crafted serialized object to Microsoft SharePoint. When SharePoint deserializes the object, the attacker’s code would be executed, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here is a highly simplified example of how an attacker might exploit this vulnerability:
```
POST /_vti_bin/client.svc HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer malicious_serialized_object
{ "malicious_serialized_object": "..." }
```
In this example, the attacker sends a POST request to a vulnerable endpoint on the target SharePoint server. The malicious serialized object is included in the Authorization header and body. When the SharePoint server deserializes the object, it inadvertently executes the attacker’s code. It’s important to note that this is a conceptual example, and actual exploitation would likely be more complex and require a deep understanding of Microsoft SharePoint’s internals.
As a cybersecurity expert, I strongly recommend applying the vendor’s patch as soon as possible to prevent potential exploits. If the patch cannot be applied immediately, consider using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure.

Product | Affected Versions

Windows Server | 2012, 2016, 2019, 2022
Windows 10 | All versions

How the Exploit Works

This vulnerability is based on improper access control in Windows SMB. An attacker, who has already gained initial access to the network, can exploit this flaw by sending specially crafted requests to the SMB server. These requests, due to the improper access control, are not adequately authenticated; hence, they allow the attacker to execute arbitrary code with elevated privileges, potentially leading to a full system compromise.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability. This is not a real exploit code but a demonstration of the type of malicious activity that could occur.
```
# Attacker's machine
$ echo 'exploit_code' > malicious.smb
$ smbclient //target/malicious -U 'username%password' -c 'put malicious.smb'
# Target machine
$ smbclient //localhost/malicious -U 'username%password' -c 'get malicious.smb; exec malicious.smb'
```
In this example, the attacker crafts a malicious SMB file (`malicious.smb`) that contains exploit code. They then use the `smbclient` tool to upload this file to a shared SMB directory on the target machine. On the target machine, the malicious file is executed, leading to a privilege escalation.

Mitigation

Users are advised to apply the latest vendor patches as soon as they become available. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation measures to detect and block suspicious network activities. Regularly updating and patching systems, along with continuous monitoring, are key to preventing such exploits.
