Affected Products

Product | Affected Versions

DELMIA Apriso | 2020 – 2025

How the Exploit Works

The exploit takes advantage of a missing authorization vulnerability in DELMIA Apriso. The application fails to correctly implement access controls, allowing an attacker to bypass the normal authorization process. This could potentially allow a malicious actor to gain elevated privileges on the application, giving them the ability to manipulate data and potentially compromise the entire system.

Conceptual Example Code

The following is a hypothetical example of how the vulnerability might be exploited. This pseudocode is meant to illustrate the concept and does not represent actual exploit code:

POST /delemia_endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"auth": {
"username": "attacker",
"password": "guess"
},
"action": {
"elevate_privileges": {
"user": "attacker",
"role": "admin"
}
}
}

In this example, the attacker sends a POST request to a vulnerable endpoint on the target system. The attacker uses their own low-level credentials but includes an action to elevate their privileges to an admin role. Due to the missing authorization vulnerability, the application fails to check the validity of this action, and the attacker gains elevated privileges.

Mitigation

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as temporary mitigation by detecting and blocking attempts to exploit this vulnerability.

User Interaction: None
Impact: Full system compromise or data leakage

Affected Products

Product | Affected Versions

OpenNebula Community Edition (CE) | Before 7.0.0
OpenNebula Enterprise Edition (EE) | Before 6.10.3

How the Exploit Works

The vulnerability arises due to a race condition in FireEdge, a component of OpenNebula. An attacker can exploit this race condition to generate a valid JSON Web Token (JWT) for any user without needing their credentials. By gaining a valid JWT, the attacker can impersonate a legitimate user and take control of their account, leading to a full system compromise or significant data leakage.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability. The example uses a simple HTTP request to exploit the race condition.

POST /fireedge/generateJWT HTTP/1.1
Host: target.opennebula.com
Content-Type: application/json
{ "user_id": "target_user_id" }

In this example, an attacker sends a POST request to the `/fireedge/generateJWT` endpoint with a target user’s ID. If the race condition is successfully exploited, the server responds with a valid JWT for the user, which the attacker can then use to take over the user’s account.

Mitigation Guidance

Users are strongly advised to apply the vendor patch as soon as possible to fix this critical vulnerability. For those unable to apply the patch immediately, deploying a web application firewall (WAF) or intrusion detection system (IDS) can provide a temporary mitigation against potential attacks. However, these measures are only temporary and do not fully resolve the vulnerability, so applying the vendor patch should be the top priority.

Overview

In this blog post, we delve into an intricate vulnerability that has surfaced in iperf, a widely used networking tool for measuring bandwidth performance.

Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

iperf | Before 3.19.1

How the Exploit Works

The vulnerability is located in the ‘net.c’ component of iperf. This stems from improper handling of the –skip-rx-copy function, particularly for the MSG_TRUNC in the recv function. When this function is used, a buffer overflow is triggered, creating an opening for attackers to execute arbitrary code on the system. Attackers can exploit this vulnerability remotely over a network without requiring user interaction or any privileges.

Conceptual Example Code

An attacker might exploit the vulnerability by sending a specially crafted payload to the affected iperf version. Conceptually, the malicious shell command might look like this:

iperf --skip-rx-copy -c target.example.com -p 5201 -F <file_with_malicious_payload>

In this example, `target.example.com` is the vulnerable system running iperf, `5201` is the port on which iperf is running, and `file_with_malicious_payload` contains the malicious code that triggers the buffer overflow.
The above is just a conceptual example and the exact payload would depend on the attacker’s objective, the specific system configuration, and other factors.

Mitigation and Recommendations

To mitigate this vulnerability, users of the affected iperf versions are strongly advised to apply the vendor-provided patch. In the interim, until the patch is applied, security measures such as Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can be used for temporary mitigation. It is also recommended to review system logs and network traffic for any suspicious activity that may indicate an attempted or successful exploit of this vulnerability.
As a part of good security hygiene, users should always keep their software up-to-date, apply patches promptly, and monitor systems for unusual behavior.

Vulnerability Summary

CVE ID: CVE-2025-47175
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Microsoft Office PowerPoint | All versions prior to the vendor patch

How the Exploit Works

The vulnerability exploits a use-after-free condition within the PowerPoint application. In programming, a “use after free” flaw occurs when a program continues to use memory after it has been freed and can be re-allocated for other tasks. This can lead to a number of undesirable outcomes, including code corruption, faulty executions, or in more severe cases like this, unauthorized code execution.
In the case of CVE-2025-47175, an attacker can craft a malicious PowerPoint document that, when opened by a user, exploits the use after free vulnerability to execute arbitrary code. This code runs with the same privileges as the user, potentially leading to a full system compromise if the user has administrative rights.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited. This pseudo-code represents a potential malicious payload embedded in a PowerPoint document:

def exploit_CVE-2025-47175():
payload = """
# Arbitrary code here
"""
create_powerpoint_document_with_payload(payload)
if exploit_successful:
execute_code_with_current_user_privileges()

This pseudo-code represents the creation of a PowerPoint document containing a malicious payload. If the exploit is successful (i.e., the document is opened by a user, and the use-after-free condition is triggered), the arbitrary code is executed with the same privileges as the current user.
The exact nature of the code would depend on the attacker’s goal, but could include actions such as downloading additional malware, creating a backdoor, or exfiltrating sensitive data.

Overview

The cybersecurity landscape is constantly evolving with new threats emerging on a regular basis. One such threat that has come to light recently is the CVE-2025-47174 vulnerability. This vulnerability is a heap-based buffer overflow in Microsoft Office Excel. This vulnerability is of significant concern as it allows an unauthorized attacker to execute code locally.

Vulnerability Summary

CVE ID: CVE-2025-47174
Severity: High (CVSS 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Microsoft Office Excel | All versions prior to patch

How the Exploit Works

This exploit takes advantage of a heap-based buffer overflow in Microsoft Office Excel. A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory, or buffer, than it can hold. In this case, the overflow is happening in the heap, a region of a computer’s memory space that is used for dynamic memory allocation. An attacker can manipulate this vulnerability to execute arbitrary code on the system running the vulnerable software.

Conceptual Example Code

While we do not provide actual exploit code, the following conceptual example illustrates how an attacker might use a crafted Excel spreadsheet to exploit this vulnerability:

# Hypothetical Python-based exploit
import malicious_module
def create_exploit():
buffer = "A" * 5000  # Overflow the buffer
malicious_code = malicious_module.generate_code()  # Generate malicious code
spreadsheet = open("exploit.xls", "w")
spreadsheet.write(buffer + malicious_code)
spreadsheet.close()
create_exploit()

In this conceptual example, the attacker creates an Excel spreadsheet with a large amount of data (“A” * 5000) to overflow the buffer. They then append malicious code to this overflowed buffer and save it within an Excel file (`exploit.xls`). When this file is opened in a vulnerable version of Excel, the overflow occurs, executing the malicious code.

Overview

In this post, we’re exploring a significant cybersecurity vulnerability identified as CVE-2025-47173. This vulnerability lies within Microsoft Office, a suite of productivity applications used by millions of individuals and businesses worldwide. This flaw stems from improper input validation, allowing an attacker to execute code locally and potentially compromise the system or cause data leakage.

Affected Products

Product | Affected Versions

Microsoft Office | All versions before the latest patch

How the Exploit Works

The vulnerability lies in the way Microsoft Office validates user input. An attacker can exploit this by crafting malicious input that is not properly sanitized by the application. This could be in the form of a document or a script embedded within a document. When this document is opened by a victim, the embedded code is executed locally. This could lead to actions ranging from unauthorized data access to complete control over the system depending on the user’s privileges.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited using a macro embedded in an Office document:

Sub Auto_Open()
Dim cmd As String
cmd = "Shell(""cmd.exe /c echo This is a test > C:\test.txt"", vbNormalFocus)"
Call VBA.Interaction.CallByName(Application, cmd, VBA.CallType.Method)
End Sub

This example showcases an Office macro that, when opened, will execute a command using the Windows command prompt. This is a benign example, writing “This is a test” to a text file in the root of the C drive, but it demonstrates how an attacker could execute arbitrary commands.

Mitigation Guidance

Users are advised to apply the vendor-provided patch immediately to mitigate this vulnerability. In the absence of a patch, the use of Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can provide temporary mitigation. These systems can detect and block attempts to exploit known vulnerabilities, providing an added layer of security. However, these are not foolproof, and applying the vendor patch remains the most effective solution.
It is also recommended to be cautious when opening Office documents from unknown sources and to disable macros where possible, as these are commonly used as an attack vector. It’s important to keep your software updated and follow best practices for cybersecurity to reduce your risk of exploitation.

Attack Vector: Local
Privileges Required: None
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

Microsoft Office Word | All versions before patch

How the Exploit Works

The exploit takes advantage of a heap-based buffer overflow vulnerability in Microsoft Office Word. An attacker sends a specially crafted Word document to the victim. When the victim opens this document, the buffer overflow is triggered. This causes data to be written beyond the buffer’s boundary, leading to arbitrary code execution in the context of the current user.

Conceptual Example Code

The actual exploit would require a sophisticated understanding of buffer overflows and intricate knowledge of Word’s internal workings. However, a conceptual version can be represented as follows:

class BufferOverflow:
def __init__(self, buffer_size):
self.buffer = [None]*buffer_size
def overflow(self, data, index):
self.buffer[index] = data
# Attacker creates buffer overflow object
exploit = BufferOverflow(10)
# Attacker overflows buffer with malicious code
for i in range(20):
exploit.overflow("malicious code", i)

In this conceptual example, the BufferOverflow class represents a buffer in Word. The attacker is able to overflow the buffer by writing more data to it than it can hold.

Mitigation Guidance

Microsoft has released a patch to address this vulnerability. Users are strongly advised to apply this patch immediately to protect against potential attacks. Until the patch can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These tools can help to identify and block attempts to exploit the vulnerability.
It’s essential to remain vigilant and ensure that all software, especially widely-used ones like Microsoft Word, are regularly updated to the most recent versions to stay protected against such vulnerabilities.
