rConfig 8.0.0 before 8.2.13 contains an authentication bypass vulnerability that allows unauthenticated attackers to self-register accounts with full Administrator privileges due to a duplicate bare Auth::routes() call in routes/web.php that re-enables the POST /register route after it was explicitly disabled. Attackers can register a new account that is immediately authenticated with Admin-level access because the registration controller does not assign a role and the users.role column defaults to Admin, enabling access to stored device credentials, user data, and API token issuance.

AnalysisAI
Unauthenticated administrator account registration in rConfig 8.0.0 through the affected releases lets any remote attacker create a fully privileged Admin user by hitting a POST /register route that was supposed to be disabled. A duplicate bare Auth::routes() call in routes/web.php re-enables self-registration, and because the registration controller never assigns a role while the users.role column defaults to Admin, the new account is instantly authenticated with full administrative rights. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The only prerequisite is network reachability to the rConfig web application's POST /register endpoint on an affected version (8.0.0 before the fix). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H) scoring 9.3 is consistent with the description: network-reachable, no authentication, no user interaction, no special preconditions, and full confidentiality/integrity/availability impact on the application. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach the rConfig web interface sends a single crafted POST /register request with a chosen username and password, receives an account that is immediately authenticated at Admin level, and logs into the console. From there they browse stored device configurations and credentials, issue API tokens, and pivot into the managed network infrastructure. … |
| Remediation | Upgrade rConfig to the fixed release - the description cites 8.2.13, though the vendor release reference lists 8.2.10, so verify the exact patched version via the GitHub advisory GHSA-w3hx-9cxg-5ccr before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, immediately isolate affected rConfig 8.0.0+ instances from untrusted networks and verify your installed version. …
