Affected Products

Product | Affected Versions

V-SFT | v6.2.5.0 and earlier

How the Exploit Works

The vulnerability lies in the VS6MemInIF!set_temp_type_default function of V-SFT. A specially crafted V7 or V8 file, when opened, triggers an out-of-bounds write. This can lead to a system crash, information disclosure, or even arbitrary code execution. The attacker would need to convince the user to open the malicious file, which might be disguised as a legitimate document or sent via a phishing email.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited. In this case, the attacker sends a specially crafted V7 or V8 file to the victim. This file, when opened with V-SFT, triggers the vulnerability:

# Attacker crafts a malicious V7 or V8 file
$ craft-malicious-file -o exploit.v7 "malicious_payload"
# The victim opens the malicious file with V-SFT
$ v-sft open exploit.v7

This shell command example demonstrates the simplicity with which an attacker could exploit this vulnerability, provided they have crafted the malicious file correctly and managed to convince the victim to open it.

Recommended Mitigations

To mitigate this vulnerability, it is highly recommended to apply the vendor-supplied patch as soon as it becomes available. If the patch is not immediately available or cannot be applied in a timely manner, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation. These tools can detect and block attempts to exploit this vulnerability, providing a crucial layer of defense. However, they are not a permanent solution and should be used in conjunction with other security measures, such as user education and software patching.

Affected Products

Product | Affected Versions

V-SFT | v6.2.5.0 and earlier

How the Exploit Works

The vulnerability exists in VS6EditData.dll!CWinFontInf::WinFontMsgCheck function of V-SFT software. An attacker can exploit it by creating and sending specially crafted V7 or V8 files to a target system with the vulnerable software. Once the file is opened, it triggers a free of pointer not at the start of the buffer, causing the system to crash or potentially allowing the attacker to execute arbitrary code or disclose information.

Conceptual Example Code

The following is a conceptual representation of how an attacker might create a malicious V7 or V8 file to exploit the vulnerability:

# conceptually creating a malicious V8 file
malicious_file = V8File()
malicious_file.craft_exploit_payload("arbitrary code")
malicious_file.save("exploit.v8")
# conceptually sending the malicious file to the target system
target_system = NetworkSystem("target.example.com")
target_system.send_file("exploit.v8")

Upon the target system opening this maliciously crafted file with the vulnerable V-SFT software, the exploit would be triggered.
Remember, this is a conceptual example and not actual exploit code. Always follow ethical guidelines when dealing with vulnerabilities.

Mitigation Guidance

To mitigate the risks associated with CVE-2025-47749, users and administrators of V-SFT software should apply the patch provided by the vendor as soon as possible. In instances where immediate patching is not feasible, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. In addition, users should be cautious when opening V7 or V8 files from untrusted sources.

Attack Vector: Local
Privileges Required: Low
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

GNU C Library | 2.27 to 2.38

How the Exploit Works

The vulnerability exists due to the way GNU C Library handles the LD_LIBRARY_PATH environment variable. An attacker can manipulate this variable to control the loading of a dynamically shared library in statically compiled setuid binaries that call dlopen. This includes internal dlopen calls after setlocale or calls to NSS functions such as getaddrinfo. As a result, the attacker could execute arbitrary code on the system with the privileges of the user running the affected application.

Conceptual Example Code

The below pseudocode illustrates how the vulnerability might be exploited:

# Attacker sets the LD_LIBRARY_PATH to their malicious library
export LD_LIBRARY_PATH=/path/to/attacker/library
# Attacker runs the setuid binary that loads a library using dlopen
./vulnerable_binary

In this example, the vulnerable_binary would load the attacker’s library instead of the intended one, leading to the execution of the attacker’s code.
It’s crucial to note that this is a simplified representation. The real-world exploitation of this vulnerability could be complex and depends on various factors, including the specific configuration and usage of the affected system.

Product | Affected Versions

UTT HiPER 840G | up to 3.1.1-190328

How the Exploit Works

The vulnerability lies in the handling of the file /goform/formPictureUrl in the UTT HiPER 840G. The application fails to properly validate the input for the argument ‘importpictureurl. By manipulating this argument, an attacker can cause a buffer overflow. This allows the attacker to overwrite memory beyond the buffer boundaries, potentially causing a system crash or, worse, allowing the execution of arbitrary code.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This example uses an HTTP POST request with a likely malicious payload to the ‘/goform/formPictureUrl’ endpoint.

POST /goform/formPictureUrl HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "importpictureurl": "A"*10000 }   // Buffer overflow triggered by oversized string

In this example, the oversized string “A”*10000 triggers the buffer overflow. This is a conceptual example and the actual exploit might involve more complex payloads.

Recommended Mitigation

The best course of action is to apply the vendor patch as soon as it becomes available. However, as the vendor has not yet responded to the vulnerability disclosure, users are advised to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These tools can be configured to detect and block attempts to exploit this vulnerability.

Affected Products

Product | Affected Versions

NI Circuit Design Suite | 14.3.0 and prior versions

How the Exploit Works

The vulnerability is triggered when a user opens a specially crafted .sym file with the SymbolEditor in the NI Circuit Design Suite. The .sym file contains malicious code that causes a stack-based buffer overflow in the DrObjectStorage::XML_Serialize() function. This buffer overflow leads to memory corruption, which can result in arbitrary code execution or information disclosure.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could look somewhat like this:

# Special crafted .sym file
malicious.sym
# Malicious code inside .sym file
<DrObjectStorage::XML_Serialize>
overflow_data = 'A' * 10000  # Buffer overflow caused due to excessive data
</DrObjectStorage::XML_Serialize>

In this hypothetical example, the ‘A’ * 10000 is the excessive data that causes the buffer overflow. When the user opens this malicious .sym file, the overflow_data is processed by the DrObjectStorage::XML_Serialize() function, leading to a buffer overflow, and hence the memory corruption vulnerability.
Please note that this is a conceptual example, and real-world exploitation might involve more complex and specific code.

Recommended Mitigation

Users of the affected software should apply any patches provided by the vendor as soon as they are available. In the meantime, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation strategies, potentially preventing the execution of the malicious .sym file and reducing the risk of system compromise or data leakage.

How the Exploit Works

The exploitation of this vulnerability requires a user to open a specially crafted .sym file. The memory corruption occurs due to an out of bounds read in the Bitmap::InternalDraw() function when using the SymbolEditor of the NI Circuit Design Suite. This corruption leads to the potential for information disclosure or arbitrary code execution.

Conceptual Example Code

Here’s a hypothetical example of how an attacker might use this vulnerability. Note that this is a conceptual illustration and not actual exploit code:

// Assumed .sym file structure
SymFile maliciousSymFile = new SymFile();
// Crafting the malicious bitmap data
Bitmap maliciousBitmapData = new Bitmap();
maliciousBitmapData.overflowData("arbitrary data to trigger out of bounds read");
// Embedding the malicious bitmap data into the .sym file
maliciousSymFile.embedBitmap(maliciousBitmapData);
// The .sym file is then saved and sent to the victim
maliciousSymFile.save("malicious.sym");

In this scenario, the attacker creates a .sym file with embedded malicious bitmap data designed to trigger an out of bounds read. The crafted file is then sent to the victim, who opens it with the SymbolEditor, triggering the exploit.

Mitigation

Users of the affected versions of NI Circuit Design Suite are advised to apply the vendor-supplied patch as soon as possible. As a temporary mitigation, Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can be used to detect and block attempts to exploit this vulnerability. However, this is only a stop-gap measure and does not remove the vulnerability from the system. For full remediation, the patch should be applied.
