Inductive Automation Ignition ResponseParser Notification Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Inductive Automation Ignition. User interaction is required to exploit this vulnerability in that the target must connect to a malicious server. The specific flaw exists within the ResponseParser method. 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-22067.

Detection & IOCsextracted from sources · hover to see the quote

→The vulnerability is triggered when a target user connects to a malicious server — monitor for Ignition client processes initiating unexpected outbound connections to untrusted hosts, particularly during deserialization in the ResponseParser method. ↗
→Focus detection on the ResponseParser notification handling code path in Inductive Automation Ignition; deserialization of untrusted data here can lead to arbitrary code execution in the context of the current user. ↗

·Exploitation requires the victim Ignition client to actively connect to an attacker-controlled malicious server; purely passive or server-side detection is insufficient without also monitoring client-initiated connections. ↗
