How the Exploit Works
An attacker crafts a malicious DGN file, which when imported or linked into Autodesk AutoCAD, triggers a memory corruption vulnerability. This corruption allows the attacker to execute arbitrary code in the context of the current process. The executed code could compromise the system or lead to data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This pseudocode represents a malicious DGN file containing a payload that triggers the memory corruption.
# Pseudocode representing a DGN file with a malicious payload
class MaliciousDGN {
payload = "<arbitrary_code_to_execute_in_context_of_current_process>"
execute() {
corrupt_memory(this.payload)
}
}Note: This is a conceptual representation and does not reflect actual code that could be used to exploit this vulnerability.
Mitigation Guidance
Users are advised to apply the vendor patch as soon as it is available to mitigate the risk posed by this vulnerability. As a temporary mitigation measure, users could use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to help detect and prevent exploitation attempts.
