Impact: System Compromise or Data Leakage

Affected Products

Product | Affected Versions

Windows | All current versions prior to patch

How the Exploit Works

The exploit occurs when an authorized user manipulates the Windows Cred SSProvider Protocol by overloading the memory buffer with more data than it can handle. This causes a heap-based buffer overflow, a type of vulnerability that overwrites the memory and can be used to run arbitrary code with elevated privileges. The attacker can then initiate unauthorized actions, such as stealing sensitive data or taking control of the system.

Conceptual Example Code

Below is a simplified conceptual representation of how an attacker might exploit this vulnerability. Note that the code is conceptual and does not represent an actual exploit.
```
# Attacker's malicious code
buffer = "A" * 8000 # Excessive data causing the buffer overflow
# Command to be executed with escalated privileges
command = "echo 'System Compromised'"
# Overwrite the buffer and execute the command
exploit = buffer + command
# Send the exploit to the vulnerable protocol
send_to_cred_ssprovider(exploit)
```
In this conceptual example, the attacker crafts an excessive amount of data, represented by “A” * 8000, causing a buffer overflow. They then append a command to be executed with escalated privileges. The exploit is sent to the Cred SSProvider Protocol, which fails to handle the excessive data and ends up executing the attacker’s command.

Mitigation and Prevention

To mitigate the CVE-2025-47987 vulnerability, users should immediately apply the vendor-released patch. If the patch cannot be applied immediately, temporary mitigation can be achieved using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and prevent exploit attempts. Regular system updates and security audits should also be part of a proactive cybersecurity strategy to prevent similar vulnerabilities in the future.

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.
