Lifecycle Timeline
3DescriptionCVE.org
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the device-webapi-request Socket.IO handler in server/runtime/index.js permits an authenticated non-admin runtime user to control property.address, causing the FUXA server to issue an outbound HTTP or HTTPS request and return the response body to the requesting socket. The attacker can use the server as a read SSRF oracle against reachable internal services or cloud metadata endpoints, with impact depending on the FUXA host's deployment network. This issue is fixed in version 1.3.3.
AnalysisAI
Server-Side Request Forgery in FUXA 1.3.2 and earlier allows authenticated non-admin runtime users to weaponize the FUXA server as an outbound HTTP proxy, reading responses from internal services and cloud metadata endpoints. The vulnerability exists in the device-webapi-request Socket.IO handler, which applies no ownership or allowlist validation to the user-controlled property.address parameter before issuing the request. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active, authenticated session as a non-admin runtime user on the FUXA instance - guest or unauthenticated access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 4.0 score of 6.0 (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N) accurately frames the primary risk: network-reachable, low-privilege exploitation with high confidentiality impact limited to what the FUXA server can reach. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary fix is upgrading to FUXA version 1.3.3, available at https://github.com/frangoteam/FUXA/releases/tag/v1.3.3. … Detailed patch versions, workarounds, and compensating controls in full report. |
