CVE-2024-22387

Severity: Medium CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:H

Components affected: Controller 6000 and Controller 7000

Reported by: Gallagher Internal

Active exploitation of vulnerability*: No

Description of vulnerability: 
External Control of Critical State Data (CWE-642) in the Controller 6000 and Controller 7000 diagnostic web interface allows an authenticated user to modify device I/O connections leading to unexpected behavior that in some circumstances could compromise site physical security controls. Gallagher recommend the diagnostic web page is not enabled (default is off) unless advised by Gallagher Technical support. This interface is intended only for diagnostic purposes.

This issue affects: 9.10 prior to vCR9.10.240520a (distributed in 9.10.1268(MR1)), 9.00 prior to vCR9.00.240521a (distributed in 9.00.1990(MR3)), 8.90 prior to vCR8.90.240520a (distributed in 8.90.1947 (MR4)), 8.80 prior to vCR8.80.240520a (distributed in 8.80.1726 (MR5)), 8.70 prior to vCR8.70.240520a (distributed in 8.70.2824 (MR7)), all versions of 8.60 and prior.

Mitigation: Ensure dipswitch 1 is turned off on all Controllers and the option, "Dipswitch 1 controls the diagnostic web interface", is not checked in Configuration Client on Controller property pages. Do not use the Controller override, "Enable WWW Connections". Refer to the Gallagher Command Centre Hardening Guide for more details.
