Exploitation Conditions

Requires an existing authenticated account on the Command Centre Server holding at least low-level Operator privileges (PR:L); it is NOT remotely exploitable by anonymous actors. The limiting factors are significant: the attacker must already be a trusted, provisioned Operator inside the physical-access-control management system, and exploitation only reveals limited cardholder personal data - no write access, configuration change, or availability impact. Affected builds are specifically 9.30.1874 (MR1), 9.20.2337 (MR3), and 9.10.3194 (MR6); environments on other/patched builds are not affected. No special non-default feature toggle is named in the description - the over-broad data visibility occurs through normal cardholder viewing by an under-privileged operator.

Impact

This is a low-to-moderate priority issue, not a high-urgency threat. The vendor-supplied CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, base 5.5 MEDIUM) describes a confidentiality-only authorization flaw: a user who is ALREADY an authenticated, privileged Operator can view limited cardholder personal data beyond their intended permission scope. There is no integrity or availability impact and no privilege escalation. The EPSS score is very low (0.13%, 3rd percentile), consistent with the absence of any public exploit and the fact that exploitation requires an existing trusted insider account rather than remote reach. This CVE is NOT in CISA KEV and no POC is referenced, so there is no evidence of active exploitation - no public exploit identified at time of analysis. Note one conflict worth flagging: the input Tag labels this 'Authentication Bypass,' but the description and CWE-359 (Exposure of Private Personal Information) describe an AUTHORIZATION/information-disclosure problem affecting an already-authenticated operator - it is not an authentication bypass. Also, the description says 'limited personal data,' which arguably supports a Confidentiality impact of Low rather than the vendor's High; this is an honest point of disagreement, not a confirmed error. Overall: real but modest insider-trust confidentiality risk, appropriately prioritized below internet-facing or RCE issues.

Exploit ScenarioDerived

A low-privileged but legitimate Command Centre Operator - for example a guard-desk or departmental operator without HR/security-admin rights - navigates to a Cardholder record and is able to view limited personal details (PII) that their role should not expose. No public exploit code is required or known; the flaw is triggered through normal application use by an already-authenticated insider. Because the CVSS vector is AV:L/AC:L/PR:L/UI:N, exploitation is simple for anyone with any operator-level access.

AnalysisAIv1 – Oct 08, 2026

Over-broad cardholder data visibility in Gallagher Command Centre Server builds 9.30.1874 (MR1), 9.20.2337 (MR3) and 9.10.3194 (MR6) allows a low-privileged, already-provisioned Operator to view limited personal data about a Cardholder that their role should not expose, due to insufficient authorization filtering on cardholder records (CWE-359). Exploitation requires an authenticated Operator account with at least low-level privileges on the Command Centre Server (CVSS:3.1/AV:L/AC:L/PR:L/UI:N) and yields read-only disclosure of a constrained set of personal fields - there is no write, configuration-change or availability impact. No public exploit has been identified at time of analysis, EPSS is 0.13% (3rd percentile) and the issue is not in CISA KEV, so this is a low-to-moderate priority privacy/authorization defect rather than a high-urgency threat.

RemediationAI

Apply the fixed Command Centre Server build published in the vendor advisory at https://security.gallagher.com/en-NZ/Security-Advisories/CVE-2025-35981 - Gallagher addresses issues of this class through maintenance releases (MR) on each supported train (9.10, 9.20, 9.30), so administrators of the exact affected builds 9.30.1874 (MR1), 9.20.2337 (MR3) and 9.10.3194 (MR6) should consult that advisory page for the specific superseding build numbers rather than assuming any patch level; no independent fix version was confirmed in the supplied data. Because the exposure only materialises through a legitimate Operator account, the most effective compensating control while awaiting an upgrade is strict least-privilege review of Command Centre Operator roles - remove or narrow access for accounts that have no operational need to open cardholder records, accepting the trade-off that staff who legitimately handle credential or photo data may need temporary elevation. Additionally, enable and review Command Centre audit/operator activity logging for cardholder record views outside a role's expected scope, and treat any such anomalous internal access as a potential indicator of exploitation; this monitoring does not prevent the disclosure, but it is the only practical detective measure given that the flaw triggers under normal cardholder viewing and cannot be blocked by network segmentation or by restricting the listening port. There is no public exploit code and no known active exploitation, so emergency out-of-band change windows are not warranted; schedule the fix in a routine maintenance cycle.

Affected ProductsAI

Gallagher Command Centre Server, specifically builds 9.30.1874 (MR1), 9.20.2337 (MR3) and 9.10.3194 (MR6) as enumerated in the vulnerability description; environments on other or subsequently patched builds are not stated to be affected. This is a server-side Command Centre component (the management server hosting cardholder and access-control data), and exploitation presupposes an existing Operator account on that server rather than a network-facing anonymous interface. No CPE identifiers were provided with the intelligence, so version identification should be confirmed against the build string of the installed Command Centre Server. The vendor advisory for this CVE is available at https://security.gallagher.com/en-NZ/Security-Advisories/CVE-2025-35981.

Technical ContextAI · show details

Gallagher Command Centre is a physical security management platform that centralises access control, alarm monitoring and cardholder management, holding personally identifiable information such as cardholder names, credentials and related records. The flaw is an instance of CWE-359 (Exposure of Private Personal Information to an Unauthorized Actor), meaning the role-based authorization layer that is supposed to scope a given Operator's view of cardholder data does not fully apply when cardholder records are queried or displayed, so an Operator with legitimate but limited privileges sees fields outside their granted permission set. The authoritative assessment rates this AV:L/AC:L/PR:L/UI:N/S:U with low confidentiality impact (C:L) - an inside-the-system, authenticated scenario with no user interaction, no scope change and no integrity or availability effect. Note that the supplied feed tag 'Authentication Bypass' is a mischaracterisation: the CVSS vector requires PR:L, so an Operator must already be authenticated and provisioned, and the defect is an authorization/least-privilege failure, not a break of authentication. The vendor advisory at https://security.gallagher.com/en-NZ/Security-Advisories/CVE-2025-35981 (reported by disclosures@gallagher.com) is the authoritative technical reference; no CPE strings were included in the supplied intelligence.
