How the Exploit Works
The exploitation of this vulnerability revolves around the deserialization of untrusted data within the project file parsing process of the DTM Soft application. An attacker crafts a malicious project file that, when loaded by the DTM Soft application, triggers the deserialization process. This process inadvertently executes the malicious code embedded in the project file, leading to remote code execution.
Conceptual Example Code
The following pseudocode demonstrates conceptually how the vulnerability might be exploited:
class maliciousProjectFile:
def __reduce__(self):
return (os.system, ('INSERT MALICIOUS COMMAND HERE',))
malicious_payload = pickle.dumps(maliciousProjectFile())
# This represents the action of loading the malicious project file
loadProjectFile(malicious_payload)In this conceptual example, a malicious project file class is defined that, when unpickled (deserialized), results in the execution of a system command. This object is then serialized and represented as a project file that would be loaded by the DTM Soft application, triggering the vulnerability.
Mitigation Guidance
The best course of action to mitigate this vulnerability is to apply the patch provided by the vendor, Delta Electronics. In scenarios where immediate patching is not possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. These systems can be configured to detect and block attempts to exploit this vulnerability, providing a layer of security until the official patch can be applied.
