Description
Allowing privilege escalation violates least privilege and could allow an attacker to gain unauthorized access to sensitive resources or execute arbitrary code.
How to fix?
Set allowPrivilegeEscalation to false.
Set the allow_privilege_escalation attribute to false.
Example Configuration
resource "kubernetes_pod_security_policy" "allowed" {
metadata {
name = "terraform-example630-1"
}
spec {
privileged = false
allow_privilege_escalation = false
read_only_root_filesystem = true
run_as_user {
rule = "MustRunAsNonRoot"
}
se_linux {
rule = "RunAsAny"
}
supplemental_groups {
rule = "MustRunAs"
range {
min = 1
max = 65535
}
}
fs_group {
rule = "MustRunAs"
range {
min = 1
max = 65535
}
}
}
