CVE-2020-10644Known exploitationPublic exploitNetwork attack vector

Information disclosure via unwhitelisted project-diff deserialization

Published Jun 9, 2020 · Updated Aug 4, 2024

Deserialization in Inductive Automation Ignition 7 Gateway before 7.9.14 and Ignition 8 Gateway before 8.0.10 lets remote attackers read project data. The unauthenticated ProjectDownload.getDiffs method passes attacker-supplied Base64 project snapshots to decodeToObjectFragile without a class whitelist, which invokes ObjectInputStream.readObject. The exposed project-diff function returns sensitive project content; a separate gadget-library flaw is required to extend this issue into code execution.
