Overview
The vulnerability, identified as CVE-2025-8894, is a Heap-Based Overflow vulnerability that affects certain Autodesk products. It can be triggered by a maliciously crafted PDF file. This vulnerability is of significant concern as it allows an attacker to potentially compromise the system, leak data, or execute arbitrary code in the context of the current process.

A new way to communicate
Ameeba Chat is built on encrypted identity, not personal profiles.
Message, call, share files, and coordinate with identities kept separate.
- • Encrypted identity
- • Ameeba Chat authenticates access
- • Aliases and categories
- • End-to-end encrypted chat, calls, and files
- • Secure notes for sensitive information
Private communication, rethought.
Product | Affected Versions
Autodesk AutoCAD | All versions prior to 2025
Autodesk Revit | All versions prior to 2025
How the Exploit Works
The exploit works by an attacker creating a malicious PDF file and persuading a user to open it using an affected Autodesk product. The crafted PDF file contains specific data that triggers a Heap-Based Overflow in the software. This overflow can result in a crash, allow the attacker to read sensitive data, or execute arbitrary code within the context of the current process.
Conceptual Example Code
A conceptual example of how the vulnerability might be exploited could be a crafted PDF file with embedded malicious code. This code is structured to overflow the heap memory when the file is parsed, as shown in the pseudocode below:
def create_malicious_pdf():
buffer = "A" * 5000 # overflow the heap
pdf = PDF()
pdf.add(buffer)
pdf.save("malicious.pdf")
create_malicious_pdf()This is a conceptual example and the actual exploit details may vary.
