Code execution via unsafe Terraform deserialization
Published Jun 10, 2021 · Updated Sep 16, 2024
Unsafe deserialization in Palo Alto Networks Checkov before 2.0.139 allows remote authenticated users to execute code via a malicious Terraform file. Palo Alto Networks has not published the deserialization entry point, data format, or unsafe object-construction operation. Exploitation requires attacker-controlled Terraform to reach an affected Checkov scan, where code runs with the scanner process's privileges.
