Logic Apps Privesc

有关 SQL 数据库的更多信息，请查看：

Az - Logic Apps

(Microsoft.Resources/subscriptions/resourcegroups/read, Microsoft.Logic/workflows/read, Microsoft.Logic/workflows/write && Microsoft.ManagedIdentity/userAssignedIdentities/assign/action) && (Microsoft.Logic/workflows/triggers/run/action)

拥有此权限，您可以创建或更新 Azure Logic Apps 工作流。工作流定义了各种系统和服务之间的自动化过程和集成。

az logic workflow create \
--resource-group <resource_group_name> \
--name <workflow_name> \
--definition <workflow_definition_file.json> \
--location <location>

az logic workflow update \
--name my-new-workflow \
--resource-group logicappgroup \
--definition <workflow_definition_file.json>

然后在更改后，您可以使用以下命令运行它：

az rest \
--method post \
--uri "https://management.azure.com/subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/Microsoft.Logic/workflows/{logicAppName}/triggers/{triggerName}/run?api-version=2016-10-01" \
--body '{}' \
--headers "Content-Type=application/json"

此外，仅使用 Microsoft.Logic/workflows/write，您可以更改授权策略，例如，允许另一个租户触发工作流：

az rest --method PUT \
--uri "https://management.azure.com/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.Logic/workflows/<workflow-name>?api-version=2016-10-01" \
--body '{
"location": "<region>",
"properties": {
"definition": {
"$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"$connections": {
"defaultValue": {},
"type": "Object"
}
},
"triggers": {
"<trigger-name>": {
"type": "Request",
"kind": "Http"
}
},
"actions": {},
"outputs": {}
},
"accessControl": {
"triggers": {
"openAuthenticationPolicies": {
"policies": {
"<policy-name>": {
"type": "AAD",
"claims": [
{
"name": "iss",
"value": "<issuer-url>"
}
]
}
}
}
}
}
}
}'

Microsoft.Logic/workflows/triggers/listCallbackUrl/action

您可以获取触发器的回调 URL 并运行它。

az rest --method POST \
--uri "https://management.azure.com/subscriptions/<subscription_id>/resourceGroups/<resource_group>/providers/Microsoft.Logic/workflows/<workflow_name>/triggers/<trigger_name>/listCallbackUrl?api-version=2019-05-01"

这将返回一个回调 URL，如 https://prod-28.centralus.logic.azure.com:443/workflows/....。现在我们可以用以下方式运行它：

curl --request POST \
--url "https://prod-28.centralus.logic.azure.com:443/workflows/<workflow_id>/triggers/<trigger_name>/paths/invoke?api-version=2019-05-01&sp=%2Ftriggers%2F<trigger_name>%2Frun&sv=1.0&sig=<signature>" \
--header 'Content-Type: application/json' \
--data '{"exampleKey": "exampleValue"}'

(Microsoft.Web/sites/read, Microsoft.Web/sites/basicPublishingCredentialsPolicies/read, Microsoft.Web/sites/write, Microsoft.Web/sites/config/list/action) && (Microsoft.Web/sites/start/action)

拥有这些权限，您可以使用 ZIP 文件部署来部署 Logic App 工作流。这些权限允许执行诸如读取应用程序详细信息、访问发布凭据、写入更改和列出应用程序配置等操作。结合启动权限，您可以更新并部署具有所需内容的新 Logic App。

az logicapp deployment source config-zip \
--name <logic_app_name> \
--resource-group <resource_group_name> \
--src <path_to_zip_file>
