Short explanation
A vulnerability in SOCFortress CoPilot prior to version 0.1.76 allows low-privileged users to modify cross-tenant object-store data without proper validation.
This flaw enables a low-privileged user to tamper with evidence, blind endpoint telemetry, and poison report templates for subsequent code execution.
What should be done?
- Update SOCFortress CoPilot to version 0.1.76 or later
- Follow the vendor advisory
- Review authorization controls
Chain of evidence and sources
SOCFortress CoPilot sürüm 0.1.76 öncesinde, POST /api/agent_data_store/upload uç noktası müşteri kullanıcılarının sahiplik doğrulaması olmadan kovan ve nesne adı seçmesine izin verir.
En düşük yetkiye sahip bir kullanıcı, kiracılar arası verileri değiştirebilir, uç nokta telemetrisini körleyebilir veya rapor şablonlarını zehirleyebilir.
Bu güvenlik açığı 0.1.76 sürümünde giderilmiştir.

SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.76, `POST /api/agent_data_store/upload` in `backend/app/data_store/data_store_routes.py` permits `customer_user` callers to choose `bucket_name` and `object_name` without an allowlist, tenant prefix, ownership check or content restriction. The only file check requires a nonempty filename. The operations in `backend/app/data_store/data_store_operations.py` create missing buckets and upsert objects, allowing existing objects belonging to any tenant to be overwritten. Targets include `sysmon-configs/<customer_code>/sysmon_config.xml` distributed to managed Windows endpoints, `copilot-case-report-templates/<name>` rendered server-side, and case evidence or forensic artifacts under `copilot-cases/<case_id>/<file>` and `velociraptor-artifacts/<agent_id>/<flow_id>/<file>`. A lowest-privilege user can tamper with cross-tenant evidence, blind endpoint telemetry, poison report templates for later code execution, plant data or exhaust storage. Sibling list, download and delete routes remain restricted to admin/analyst; the exposed operation is the upload write path. This issue is fixed in version 0.1.76.
