Vulnerability AssessmentAI
| Exploitation | Exploitation requires an account that is both authenticated and explicitly authorized as an operator within Gallagher Command Centre - this maps to the CVSS PR:H (high privilege) designation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 2.7 (Low) accurately reflects the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated operator with a valid high-privilege account on the Gallagher Command Centre system navigates to the Controller 6000 or 7000 diagnostic web interface and sends a specially crafted HTTP request that triggers an unhandled exception in the controller firmware. The controller process terminates and restarts, temporarily interrupting physical access enforcement at all doors or checkpoints managed by that controller - potentially allowing tailgating or lockout at a critical access point during the restart window. |
| Remediation | The primary remediation is to upgrade Command Centre to a patched maintenance release: 9.50.1587 (MR1) containing vCR9.50.260616a, 9.40.3130 (MR3) containing vCR9.40.260616a, 9.30.3983 (MR5) containing vCR9.30.260616a, or 9.20.4349 (MR7) containing vCR9.20.260616a, as applicable to the deployed branch. … Detailed patch versions, workarounds, and compensating controls in full report. |
