Vulnerability Summary

CVE ID: CVE-2025-47971
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Windows Server | 2012, 2016, 2019
Hyper-V | All versions prior to the patch release

How the Exploit Works

This vulnerability takes advantage of a buffer over-read condition present in the handling of VHDX files. An attacker with access to the affected system can craft a specifically designed VHDX file that, when processed, forces the system to read beyond the allocated buffer. This can lead to leakage of sensitive information and, under certain conditions, can be leveraged to execute arbitrary code with elevated privileges.

Conceptual Example Code

The example below is a conceptual illustration of how a malicious VHDX file might be used to exploit the vulnerability:

# Create a malicious VHDX file
echo 'base64-encoded-payload' > malicious.vhdx
# Mount the malicious VHDX
mount -t vhdx -o loop malicious.vhdx /mnt/target
# Trigger the vulnerability
cat /mnt/target/trigger

In this conceptual example, a malicious VHDX file is created and mounted to a target directory. The ‘trigger’ file within the mounted disk is then read, causing the system to over-read the buffer, which can lead to the execution of the malicious payload embedded within the VHDX file.

Mitigation Guidance

The recommended mitigation for this vulnerability is to apply the vendor-supplied patch as soon as possible. In cases where immediate patching is not feasible, temporary mitigation can be achieved by deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. Also, limit access to VHDX files to trusted users only and regularly monitor system logs for any unusual activity.
Remember, staying updated about such vulnerabilities and taking timely action is the cornerstone of effective cybersecurity management.

Affected Products

Product | Affected Versions

Windows 10 | 20H2, 21H1
Windows Server | 2019, 2022

How the Exploit Works

The vulnerability resides in the protection mechanism of Windows Virtualization-Based Security (VBS) Enclave. An authorized attacker can manipulate this flaw to bypass the intended security boundaries. By exploiting this vulnerability, an attacker could elevate their privileges on the affected system, potentially gaining control over the system or leaking sensitive data. It’s important to note that the attack is local, which means the attacker must have initial access to the system to exploit this vulnerability.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited:

# This is a conceptual example and may not represent actual exploit code
# Get a handle to the VBS Enclave
$vbsEnclaveHandle = Get-Handle -Process "VBS Enclave"
# Craft malicious payload
$maliciousPayload = New-Payload -ElevatePrivilege
# Use the handle to inject the malicious payload into the VBS Enclave
Inject-Payload -Handle $vbsEnclaveHandle -Payload $maliciousPayload

In this example, the attacker is using a hypothetical PowerShell script to first get a handle to the VBS Enclave process, crafting a malicious payload designed to elevate privileges, and then injecting this payload into the VBS Enclave using the obtained handle.
Please note that this is a simplified and conceptual representation of an exploit and may not represent the full complexity involved in a real-world attack scenario. However, it illustrates the potential severity of this vulnerability and it underlines the importance of applying the recommended mitigations promptly.

Overview

The CVE-2025-21166 is a newly identified cybersecurity vulnerability affecting versions 14.1 and earlier of the popular Substance3D – Designer software. This critical vulnerability can lead to an out-of-bounds write, a dangerous condition where arbitrary data can overwrite other data in memory, potentially leading to arbitrary code execution by the attacker. This issue is significant as Substance3D – Designer is widely used by creative professionals and organizations globally, raising the potential for system compromise and data leakage.

Vulnerability Summary

CVE ID: CVE-2025-21166
Severity: High (CVSS: 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: Arbitrary code execution, potential system compromise, and data leakage

Affected Products

Product | Affected Versions

Substance3D – Designer | 14.1 and earlier

How the Exploit Works

The vulnerability arises from the software’s improper handling of certain file inputs, leading to an out-of-bounds write. When a user opens a specially-crafted malicious file, the application can be tricked into writing data outside of its intended memory boundaries. This can cause the application to overwrite other important data in memory, potentially leading to arbitrary code execution. This code would run in the context of the current user, making it possible for an attacker to take control of the affected system.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could be through a malicious .sbs file (Substance3D’s native file format). The attacker crafts this file in such a way that it triggers the vulnerable code path when opened in Substance3D – Designer:

# Conceptual malicious .sbs file
{
"metadata": {...},
"content": "AAAAAAAAA...[more A's beyond expected boundary]...AAAAAA"
}

In this conceptual example, the `content` is filled with an excessive amount of “A” characters, which could trigger an out-of-bounds write if the application does not correctly handle this unexpectedly large input. Please note that this is simplified and conceptual; real-world exploits would likely need to incorporate more sophisticated techniques to achieve arbitrary code execution.

Mitigation Guidance

Substance3D users are strongly recommended to apply the vendor patch as soon as it becomes available to mitigate this vulnerability. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. These tools can help detect and block suspicious activities that may indicate an attempt to exploit this vulnerability. However, they are not a substitute for patching the software as they may not catch all attempts to exploit this vulnerability.

Affected Products

Product | Affected Versions

Substance3D Designer | 14.1 and earlier versions

How the Exploit Works

The vulnerability stems from an out-of-bounds write condition within the Substance3D Designer software. This condition occurs when the software attempts to write data beyond the memory buffer boundaries, which could corrupt the data, crash the system, or allow the execution of arbitrary code.
An attacker would need to craft a malicious file and convince the user to open it using the Substance3D Designer software. Once the user opens the malicious file, the exploit triggers the out-of-bounds write vulnerability, potentially leading to arbitrary code execution in the context of the current user.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. Here, we consider a malicious file being opened in Substance3D Designer.

# The attacker crafts a malicious file
echo "malicious code" > exploit.sbs
# The victim unknowingly opens the malicious file
Substance3D Designer open exploit.sbs

Please note that this is a simplified and conceptual example. The actual exploit would involve a specifically crafted file that triggers the out-of-bounds condition, which then allows the arbitrary code to be executed.

Recommendations

Users of Substance3D Designer are advised to apply the patch provided by the vendor as soon as possible. In the meantime, utilizing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate the risk. However, these should not be seen as long-term solutions but rather as temporary measures until the patch can be applied. Users should also be cautious when opening files from unknown or untrusted sources.

Overview

A recently identified cybersecurity vulnerability, CVE-2025-50130, presents a significant risk to users of V-SFT and TELLUS software provided by FUJI ELECTRIC CO., LTD. This vulnerability allows a potential attacker to execute arbitrary code, potentially leading to system compromise or data leakage. Given that V-SFT and TELLUS are frequently used in industrial settings, the implications of this vulnerability could be severe, impacting not just data integrity but potentially physical operations and safety as well.

Vulnerability Summary

CVE ID: CVE-2025-50130
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: System compromise, data leakage

Affected Products

Product | Affected Versions

V-SFT | All versions prior to the vendor patch
TELLUS | All versions prior to the vendor patch

How the Exploit Works

The exploit hinges on a heap-based buffer overflow vulnerability within the VS6Sim.exe component of the V-SFT and TELLUS software. By crafting a malicious V9 or X1 file and getting the user to open it in the software, an attacker can cause a buffer overflow. This overflow can then lead to arbitrary code execution, allowing the attacker to potentially compromise the system or leak data.

Conceptual Example Code

Please note that the following example is a conceptual representation of how the exploit might work. It’s not actual code and can’t be used to exploit the vulnerability. The purpose is to demonstrate the underlying principles of the exploit.

#include <stdlib.h>
#include <string.h>
void vulnerable_function(char *input) {
char buffer[256];
strcpy(buffer, input);
}
int main(int argc, char **argv) {
char large_input[512];
memset(large_input, 'A', 511);
large_input[511] = '\0';
vulnerable_function(large_input);
return 0;
}

In this conceptual example, a large input is copied into a smaller buffer, causing a buffer overflow. In the context of the CVE-2025-50130 vulnerability, an attacker might use a similar approach to overflow the buffer in the VS6Sim.exe component with malicious code.

Mitigation

FUJI ELECTRIC CO., LTD. recommends applying the vendor patch to mitigate the vulnerability. In the absence of a patch, or until one can be applied, Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. However, these are not long-term solutions and the patch should be applied as soon as possible to fully protect against the exploit.

Overview

Recently, a new vulnerability has been identified, listed as CVE-2025-27061. This vulnerability, which involves memory corruption while handling subsystem failures during the parsing of video packets, can be exploited by malicious entities to potentially compromise systems or leak sensitive data.

User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Vendor Product A | Versions X.Y.Z
Vendor Product B | Versions X.Y.Z

How the Exploit Works

The exploit works by sending malformed video packets to the targeted system. During the parsing of these packets by the video firmware, a memory corruption occurs while handling subsystem failures. This memory corruption can ultimately lead to a system compromise or data leakage. The exploit does not require high privilege levels or user interaction, making it a significant threat.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability.

import socket
def exploit(target_ip, target_port):
# create a socket object
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# connect to the target
sock.connect((target_ip, target_port))
# malformed video packet
malicious_payload = "malicious video packet data here...."
# send the malicious payload
sock.send(malicious_payload)
# close the connection
sock.close()
# specify target details
target_ip = "192.168.0.1"
target_port = 12345
# run the exploit
exploit(target_ip, target_port)

In the above pseudocode, the attacker crafts a malformed video packet (represented by the `malicious_payload` variable) and sends it to the target system via a network connection.

Mitigation Guidance

The best course of action to mitigate this vulnerability is to apply the vendor patch as soon as it is available. If the patch is not yet available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to detect and block the specific pattern of the malformed video packets, preventing the exploit from succeeding. Regular system and security updates, along with continuous monitoring of the system for any unusual activities, are also recommended.
