SOLIDWORKS eDrawings | Desktop 2025 Release
How the Exploit Works
The vulnerability stems from a Use After Free (UAF) condition in the JT file reading procedure within SOLIDWORKS eDrawings. UAF vulnerabilities occur when an application continues to use memory after it has been freed, leading to either a crash or the execution of arbitrary code. In this case, an attacker could craft a special JT file that, when opened by a victim using SOLIDWORKS eDrawings, leads to the execution of arbitrary code.
Conceptual Example Code
The following pseudocode illustrates the potential exploit. The real attack would likely involve complex binary code and be embedded within a JT file:
# Create malicious JT file
malicious_jt_file = JTFile()
# Embed arbitrary code within the JT file
malicious_code = """
def arbitrary_code():
# Arbitrary commands here
pass
"""
malicious_jt_file.embed_code(arbitrary_code)
# Save the JT file
malicious_jt_file.save("malicious.jt")The victim would then open the “malicious.jt” file with SOLIDWORKS eDrawings, causing the embedded code to execute.
Remediation and Mitigation
All users of SOLIDWORKS eDrawings Desktop 2025 are advised to apply the vendor patch as soon as possible. If the patch cannot be applied immediately, temporary mitigation can be achieved through the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS). These systems should be configured to monitor and block suspicious activity related to the opening of JT files.
