CVE-2026-25112: Genetec RabbitMQ Privilege Escalation

CVE-2026-25112 Overview

CVE-2026-25112 is a privilege escalation vulnerability affecting the deployment of RabbitMQ within Genetec products. The flaw stems from incorrect permission assignment for a critical resource [CWE-732], allowing a local authenticated attacker to elevate privileges on the host system. Successful exploitation grants the attacker full impact against confidentiality, integrity, and availability of the affected system. Genetec has published a security advisory describing the issue and recommended remediation steps.

Critical Impact

A locally authenticated, low-privileged user can exploit insecure permissions on the RabbitMQ deployment to gain elevated privileges, resulting in full compromise of the affected host.

Affected Products

• Genetec products deploying the affected RabbitMQ component
• See the Genetec Security Advisory on RabbitMQ for the full list of affected versions
• See the Genetec Bulletin on Privilege Escalation for additional product details

Technical Details for CVE-2026-25112

Vulnerability Analysis

The vulnerability arises from improper permission assignment within the RabbitMQ deployment bundled with Genetec products. RabbitMQ is an open-source message broker used for inter-process communication between Genetec service components. When the broker is deployed with overly permissive access controls on its files, directories, or configuration, low-privileged local accounts can modify resources that run in a higher security context.

An attacker with local access and limited privileges can leverage these insecure permissions to alter configuration files, replace binaries, or modify scheduled tasks tied to the RabbitMQ service. When the service or a privileged process consumes the modified resource, the attacker's code executes with elevated privileges. The Common Weakness Enumeration classification [CWE-732] identifies this as Incorrect Permission Assignment for Critical Resource.

Root Cause

The root cause is misconfigured filesystem or service permissions applied to the RabbitMQ deployment during installation. Critical resources required by the broker are accessible to non-administrative users, violating the principle of least privilege. This configuration weakness exists in the deployment process rather than in RabbitMQ source code.

Attack Vector

Exploitation requires local access to the affected host with a low-privileged user account. No user interaction is required. The attacker identifies writable resources owned or executed by the higher-privileged RabbitMQ service, modifies them, and waits for the service to trigger the modified content. The result is code execution under the privileged service context.

No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Technical exploitation details are described in the Genetec Security Advisory on RabbitMQ.

Detection Methods for CVE-2026-25112

Indicators of Compromise

• Unexpected modifications to RabbitMQ configuration files, plugins, or service binaries within the Genetec installation directory
• New or altered scheduled tasks, services, or autoruns referencing RabbitMQ paths
• Process executions spawned by the RabbitMQ service that do not match known operational behavior
• Local user accounts writing to directories that should be restricted to administrators or service accounts

Detection Strategies

• Audit filesystem access control lists on RabbitMQ installation directories and flag any non-administrative write permissions
• Monitor file integrity on RabbitMQ configuration files, Erlang cookie files, and plugin directories
• Correlate local logon events with subsequent privileged process executions from the RabbitMQ service tree
• Review Windows Security and Sysmon logs for process creation events where a low-privileged user precedes elevated RabbitMQ child processes

Monitoring Recommendations

• Enable command-line and process creation auditing on Genetec servers hosting RabbitMQ
• Forward endpoint and host telemetry to a centralized SIEM for correlation across the Genetec deployment
• Establish a baseline of normal RabbitMQ service behavior and alert on deviations such as unexpected child processes or configuration reloads
• Track changes to local group memberships and service account privileges on affected hosts

How to Mitigate CVE-2026-25112

Immediate Actions Required

• Apply the remediation steps documented in the Genetec Security Advisory on RabbitMQ as soon as possible
• Restrict interactive local logon on Genetec servers to administrators and operational staff who require it
• Audit and remove any unnecessary local accounts on hosts running the RabbitMQ deployment
• Verify that filesystem permissions on the RabbitMQ installation directory deny write access to non-administrative users

Patch Information

Genetec has published advisories describing remediation guidance for the affected deployments. Refer to the Genetec Security Advisory on RabbitMQ and the Genetec Bulletin on Privilege Escalation for vendor-provided fixes and configuration changes. Administrators should validate the corrected permission set after applying the vendor guidance.

Workarounds

• Manually harden permissions on the RabbitMQ installation directory and configuration files to restrict access to the service account and administrators only
• Isolate Genetec servers on a dedicated management network segment to limit local access to authorized personnel
• Enforce application allowlisting on Genetec hosts to prevent execution of unauthorized binaries from RabbitMQ paths
• Disable or remove the RabbitMQ plugin directory write permission for non-service identities until the vendor remediation is fully applied

# Configuration example: restrict permissions on the RabbitMQ install directory (Windows)
icacls "C:\Program Files\Genetec\RabbitMQ" /inheritance:r
icacls "C:\Program Files\Genetec\RabbitMQ" /grant:r "Administrators:(OI)(CI)F" "SYSTEM:(OI)(CI)F"
icacls "C:\Program Files\Genetec\RabbitMQ" /remove "Users" "Authenticated Users"
