Vulnerability Summary

CVE ID: CVE-2025-5040
Severity: High (7.8 CVSS Score)
Attack Vector: Local file input
Privileges Required: None
User Interaction: Required (User must open a malicious RTE file)
Impact: System compromise, data leakage, arbitrary code execution in the current process context

Affected Products

Product | Affected Versions

Autodesk Revit | All versions prior to patch

How the Exploit Works

The exploit works by taking advantage of a flaw in the Autodesk Revit’s parsing mechanism for RTE files. A malicious actor can craft a malformed RTE file in a way that triggers a heap-based overflow when parsed by the software. This leads to a buffer overrun, which can cause the software to crash, leak sensitive data, or execute arbitrary code within the context of the current process.

Conceptual Example Code

Although it’s difficult to provide precise pseudocode for the exploit due to its complex nature, a conceptual example might look like this:

Function exploit() {
rte_file = create_malformed_RTE_file();
Autodesk_Revit.open(rte_file);
}

In this pseudocode above, the `create_malformed_RTE_file()` function represents the process of crafting a malicious RTE file that will induce a heap-based overflow. The `Autodesk_Revit.open(rte_file)` is the action of the victim opening the malicious RTE file with Autodesk Revit, thereby triggering the vulnerability.
Remember, this is a conceptual example, and exploiting this vulnerability in a real-world scenario involves a more complex set of operations.

Overview

In the realm of cybersecurity, a new vulnerability has been reported, identified as CVE-2025-5037, that affects users of Autodesk Revit, a widely-used architecture software. This vulnerability stands out due to its ability to execute arbitrary code, potentially leading to system compromise or data leakage. The severity of this vulnerability, combined with the popularity and widespread use of Autodesk Revit in the architecture and construction industries, makes it a significant threat that needs immediate attention and action.

Vulnerability Summary

CVE ID: CVE-2025-5037
Severity: High (7.8 CVSS v3 Score)
Attack Vector: Network via malicious RFA, RTE, or RVT file
Privileges Required: None
User Interaction: Required (user must open a malicious file)
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Autodesk Revit | All versions prior to the vendor patch

How the Exploit Works

The exploit takes advantage of a Memory Corruption vulnerability in Autodesk Revit. When a user opens a maliciously crafted RFA, RTE, or RVT file using Autodesk Revit, it can trigger the memory corruption, creating a security gap. This gap can be exploited by the attacker to execute arbitrary code in the context of the current process, potentially gaining unauthorized access to sensitive data or even taking control of the entire system.

Conceptual Example Code

Here is a conceptual representation of the malicious file:

$ malicious_file.rfa
BEGIN_OBJECT
{
"type": "Buffer",
"data": [ ...malicious_code... ]
}
END_OBJECT

This file, when opened in Autodesk Revit, would trigger the memory corruption vulnerability, leading to the execution of the malicious code within the data array.

Mitigation Guidance

To mitigate the impact of this vulnerability, Autodesk has released a vendor patch that users are strongly advised to apply. The update addresses the memory corruption vulnerability by sanitizing the input files and preventing the execution of any arbitrary code.
For organizations where immediate patching is not feasible due to operational constraints, deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to detect and block suspicious file activities, thereby preventing the execution of the malicious code.
While these measures can significantly reduce the risk posed by this vulnerability, they are not a substitute for a comprehensive security program. Regular software updates, user education, and robust security policies are essential in protecting against this and other types of cybersecurity threats.

Overview

The Common Vulnerabilities and Exposures database has recently confirmed the existence of an arbitrary file upload vulnerability in the WeGIA Web manager for charitable institutions. This flaw allows an attacker to upload a webshell to the server for remote code execution, making it a high-risk vulnerability. As WeGIA is commonly used by various charitable institutions to manage their operations, this vulnerability could potentially affect a large number of organizations, exposing them to potential system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-58745
Severity: Critical 9.9
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise and data leakage due to arbitrary file upload and remote code execution

Affected Products

Product | Affected Versions

WeGIA Web Manager | Versions earlier than 3.4.11

How the Exploit Works

The exploit works by taking advantage of the fact that WeGIA only checks MIME types for Excel files at the endpoint `/html/socio/sistema/controller/controla_xlsx.php`. By using magic bytes of an Excel file in a PHP file, an attacker can bypass WeGIA’s MIME type check and upload a webshell to the server. This can lead to remote code execution, potentially compromising the entire system or leading to data leakage.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a POST request with a crafted PHP file that contains the magic bytes of an Excel file.

POST /html/socio/sistema/controller/controla_xlsx.php HTTP/1.1
Host: target.example.com
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
{ "file": "<?php echo shell_exec($_GET['cmd']); ?>" }

In this example, the uploaded file is a PHP script that will execute any command passed to it via the ‘cmd’ GET parameter. This effectively allows the attacker to execute arbitrary commands on the server.

Mitigation

Users of WeGIA Web Manager are strongly advised to update their systems to version 3.4.11 or later, which contains a fix for this vulnerability. Until the update can be applied, it’s recommended to use a web application firewall (WAF) or intrusion detection system (IDS) as a temporary mitigation measure.

Overview

The CVE-2025-6377 is a serious security vulnerability discovered in the Rockwell Automation Arena®. This vulnerability has the ability to compromise the integrity of the system, potentially leading to data leakage or full system takeover.

Privileges Required: Administrator
User Interaction: Required
Impact: Execution of arbitrary code leading to potential system compromise or data leakage

Affected Products

Product | Affected Versions

Rockwell Automation Arena® | [All Previous Versions till date]

How the Exploit Works

The vulnerability originates from the Arena Simulation software’s improper handling of crafted DOE files. If a user opens a malicious DOE file within the software, it can force the software to write beyond the boundaries of an allocated object. This allows a threat actor to execute arbitrary code on the target system. For the worst-case impact, the software must be running under the context of an administrator.

Conceptual Example Code

While there are no specific details available for this exploit, an example of a similar vulnerability would involve a crafted file that contains malicious code. Here’s a conceptual example:

# Crafted malicious DOE file
$ echo "malicious code" > exploit.doe
# Open the crafted DOE file with the vulnerable software
$ Arena® exploit.doe

In this example, simply opening the crafted DOE file with the Arena® software can trigger the vulnerability, resulting in the execution of the malicious code.

Prevention & Mitigation

The best way to mitigate this vulnerability is by applying the patch provided by the vendor. In case the patch is not immediately available, using a web application firewall (WAF) or an intrusion detection system (IDS) could provide temporary mitigation. It is also recommended to restrict the software to operate under the least privilege necessary and limit the opening of untrusted files to minimize the potential impact.
