Product | Affected Versions

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

The designated vulnerability CVE-2023-49132 exploits an uninitialized pointer access in Solid Edge SE2023. This means that an attacker can craft special PAR files that trigger this vulnerability when parsed by the application. The exploitation can lead to the execution of arbitrary code in the context of the current process. This could potentially allow the attacker to perform unauthorized actions, such as modifying data, creating new accounts with full user rights, or even taking control of the system.

Conceptual Example Code

Below is a conceptual example of how an attacker might leverage this vulnerability. This pseudocode represents a malicious PAR file that could exploit the uninitialized pointer, triggering unexpected behavior:

# Pseudo code for a malicious PAR file
class MaliciousParFile:
def __init__(self):
self.payload = b"\x90" * 100  # NOP sled
self.payload += b"\xCC" * 4  # INT 3 instruction (Breakpoint)
self.payload += b"\x90" * 100  # NOP sled
def save(self, filename):
with open(filename, 'wb') as f:
f.write(self.payload)
malicious_par = MaliciousParFile()
malicious_par.save('exploit.par')

In this example, the malicious PAR file contains a payload designed to cause a breakpoint interruption when parsed by the Solid Edge SE2023 software, demonstrating the potential for code execution within the application’s process.
Please note that this is a simplified example meant for educational purposes only. Actual exploits could be much more complex and harmful.

Remediation

The mitigation guidance for the CVE-2023-49132 vulnerability is to apply the vendor patch or use Web Application Firewalls (WAF) / Intrusion Detection Systems (IDS) as temporary mitigation. Users are highly encouraged to update their Solid Edge SE2023 to V223.0 Update 10 or higher as soon as possible to protect their systems from potential attacks.
