CVE-2023-48783
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn Authorization Bypass Through User-Controlled Key vulnerability [CWE-639] affecting PortiPortal version 7.2.1 and below, version 7.0.6 and below, version 6.0.14 and below, version 5.3.8 and below may allow a remote authenticated user with at least read-only permissions to access to other organization endpoints via crafted GET requests.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencePortiPortal versions 7.2.1 and below, 7.0.6 and below, 6.0.14 and below, and 5.3.8 and below contain an IDOR (Insecure Direct Object Reference) vulnerability where authenticated users with read-only permissions can manipulate organization identifiers in GET request parameters to access sensitive endpoints belonging to other organizations, bypassing multi-tenant isolation controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FortiPortal versionAccess the FortiPortal admin interface and navigate to System > Settings > About, or use the CLI command 'fortiportal -v' or check the /opt/fortiportal/version file if accessible. Alternatively, check the HTTP response headers on the login page for version information.Affected if The installed version falls within 5.3.0-5.3.8, 6.0.0-6.0.14, 7.0.0-7.0.6, or 7.2.0-7.2.1.
-
Verify multi-tenant organization configurationIn the FortiPortal admin GUI, navigate to Organization > Organizations to list all configured organizations. If more than one organization exists, multi-tenant isolation is in use.Affected if Multiple organizations are configured in the system.
-
Identify read-only user accountsNavigate to User & Authentication > User Groups or Administration > Users to review user accounts and their assigned roles. Look for users with 'Read Only' or equivalent restricted permission profiles.Affected if Read-only or restricted-role user accounts exist in the system.
-
Review API endpoint access logsExamine FortiPortal audit logs or access logs for GET requests where the 'orgId' or 'organizationId' parameter appears. Check if these requests originate from users in one organization but reference resources in a different organization.Affected if Audit logs show GET requests with organization identifiers that do not match the requesting user's organization.
You are affected if FortiPortal version is 5.3.8 or below, 6.0.14 or below, 7.0.6 or below, or 7.2.1 or below AND the system uses multi-tenant organization isolation with users having read-only permissions.

dbcve · scoped7.0.77.2.2
Upgrade to a patched version of PortiPortal. Until an update is available, implement strict authorization validation on all endpoints to ensure users can only access resources within their own organization.
FortiPortal 5.3.9 (for 5.3.x), 6.0.15 (for 6.0.x), 7.0.7 (for 7.0.x), or 7.2.2 (for 7.2.x)
- 1. Identify the currently installed FortiPortal version from the web UI (System > Settings > About) or CLI: 'get system status'
- 2. Based on your current version, plan the upgrade to the fixed release: If running 5.3.x, upgrade to 5.3.9 or later; If running 6.0.x, upgrade to 6.0.15 or later; If running 7.0.x, upgrade to 7.0.7 or later; If running 7.2.x, upgrade to 7.2.2 or later
- 3. Download the appropriate firmware from Fortinet Customer Support portal (https://support.fortinet.com/)
- 4. Backup the FortiPortal configuration via the web UI (System > Maintenance > Backup & Restore) or CLI
- 5. Review FortiPortal upgrade documentation for any prerequisites or migration steps specific to your version path
- 6. Perform the upgrade during a planned maintenance window following Fortinet's recommended upgrade procedure
- 7. After upgrade, verify the FortiPortal version and confirm all services are operational
- 8. Validate that the fix is applied by testing that authenticated users with read-only permissions can no longer access other organization endpoints via crafted GET requests
