Product | Affected Versions

Solid Edge SE2023 | All versions < V223.0 Update 10 How the Exploit Works

The vulnerability arises from an out of bounds read past the end of an allocated structure when the affected applications parse specially crafted PAR files. This condition could be exploited by an attacker who can create and send a malformed PAR file to the victim. When the victim opens the file using the vulnerable version of Solid Edge SE2023, the attacker’s code is executed in the context of the current process, potentially compromising the system or leading to data leakage.

Conceptual Example Code

Here’s a conceptual example of how an attacker might craft a malicious payload.

# Pseudocode for creating a malicious PAR file
file = open("malicious.par", "w")
file.write("\x00"*1024) # Fill the file with null bytes
file.write("\x90"*100)  # Write a NOP sled
file.write("\x0B"*20)   # Write the exploit shellcode
file.close()

This code is a simplified representation and actual exploit code would be more complex, taking into account the specific memory layout and the exact vulnerability characteristics.

Recommended Mitigation

The best way to protect yourself from this vulnerability is to apply the vendor patch as soon as possible. If it’s not immediately feasible to apply the patch, consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation. These tools can detect and block attempts to exploit this vulnerability, providing an additional layer of security for your systems.
