Short explanation
OpenWISP Controller contains an authorization bypass vulnerability in the GET /api/v1/controller/ca/<integer-id>/crl endpoint due to missing organization scoping.
It allows an authenticated organization manager to retrieve certificate revocation lists belonging to another organization, disclosing sensitive information.
What should be done?
- Follow vendor advisories
- Apply updates when available
- Audit access to the affected endpoint
Chain of evidence and sources
OpenWISP Controller, 1.0.0 ile 1.3.2 sürümleri arasında CA CRL REST API uç noktasında organizasyon kapsamı doğrulaması yapmamaktadır.
CrlDownloadView.retrieve fonksiyonu, CA nesnesini doğrudan çözerek amaçlanan yetkilendirme sınırını atlamaktadır.
Show the technical text from the sources
OpenWISP Controller is a network and WiFi controller for provisioning, configuration management, updates, and PKI management. From 1.0.0 until 1.3.2, the GET /api/v1/controller/ca/<integer-id>/crl endpoint allows an authenticated organization manager with CA view permission to retrieve another organization's certificate revocation list by requesting its sequential CA identifier. CrlDownloadView.retrieve resolves the CA directly instead of using the organization-scoped object retrieval enforced by FilterByOrganizationManaged, bypassing the endpoint's intended authorization boundary. The response can disclose CA issuer information and revoked certificate serial numbers, but it does not expose CA private keys or allow modification. This issue is fixed in version 1.3.2.
