CVE-2025-1787 is a vulnerability classified under CWE-346 (Origin Validation Error) affecting Genetec Update Service versions earlier than 2.10.600. The flaw arises from improper validation of the origin in the service's configuration web interface, which is accessible locally. An authenticated Windows user with administrative privileges can exploit this weakness to leak sensitive configuration information from the update service. This information disclosure can facilitate privilege escalation within the Genetec Update Service context. The vulnerability requires local admin privileges to exploit, indicating that the attacker must already have significant access to the system. However, by combining this vulnerability with CVE-2025-1789, an attacker could potentially escalate privileges from a lower level. The CVSS 4.0 base score of 5.8 reflects a medium severity, considering the high complexity and required privileges. The vulnerability impacts confidentiality, integrity, and availability of the update service, as improper origin validation can lead to unauthorized actions or information leakage. No public exploits have been reported yet, but the risk remains for environments where Genetec Update Service is deployed and local admin users exist. The vulnerability highlights the importance of strict origin validation in web services, even those accessible only locally, to prevent privilege escalation and information leakage.

The primary impact of CVE-2025-1787 is the potential leakage of sensitive configuration information from the Genetec Update Service, which could be leveraged to gain elevated privileges within the service. This can undermine the integrity and confidentiality of the update process, potentially allowing an attacker to manipulate updates or disrupt service availability. Although exploitation requires local admin privileges, the vulnerability could be a stepping stone for further attacks, especially when combined with related vulnerabilities like CVE-2025-1789. Organizations relying on Genetec Update Service for security or surveillance infrastructure could face increased risk of unauthorized access or tampering with critical updates, potentially affecting operational continuity and security posture. The medium severity rating suggests a moderate risk, but the impact could be significant in environments with multiple users having local admin rights or where the update service is critical to security operations.

To mitigate CVE-2025-1787, organizations should: 1) Upgrade Genetec Update Service to version 2.10.600 or later once patches are released by the vendor. 2) Restrict local administrative privileges strictly to trusted personnel to reduce the attack surface, as exploitation requires local admin rights. 3) Implement strict access controls and monitoring on systems running the Genetec Update Service to detect unusual access or privilege escalation attempts. 4) Employ application whitelisting and endpoint protection to prevent unauthorized execution of malicious code that could exploit this vulnerability. 5) Conduct regular audits of user privileges and remove unnecessary local admin rights. 6) If patching is delayed, consider isolating systems running the update service or limiting network access to reduce exposure. 7) Monitor vendor advisories for related vulnerabilities such as CVE-2025-1789 and apply combined mitigations accordingly.
