Summary

Ultralytics from 8.4.65 is affected by a deserialization flaw in the torch_load function. The function does not properly validate user-supplied data, so it deserializes untrusted data (CWE-502). A remote attacker can execute arbitrary code in the context of the current user if the target visits a malicious page or opens a malicious file.

Description from the CNA

Ultralytics torch_load Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ultralytics. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the torch_load function. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-29652.
