CVE-2023-39476: Inductiveautomation ignition deserialization of untrusted data vulnerability

Inductiveautomation · Ignition

Inductive Automation Ignition JavaSerializationCodec Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Inductive Automation Ignition. Authentication is not required to exploit this vulnerability. The specific flaw exists within the JavaSerializationCodec class. 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 SYSTEM. Was ZDI-CAN-20291.
