The GeoVision ASManager Windows Application version 6.1.2.0 and earlier contains a critical vulnerability identified as CVE-2025-26263, which results in credentials disclosure due to improper memory handling within the ASManagerService.exe process. This vulnerability allows an attacker with system-level access and high privilege on the host machine to dump memory and extract credentials of ASManager accounts. The ASManager application is part of a suite of access and security management tools, including ASWeb (Access & Security Management), TAWeb (Time and Attendance Management), and VMWeb (Visitor Management). Exploitation does not require network access but demands local system access with elevated privileges, which could be obtained through other means such as privilege escalation or insider threat. Once credentials are disclosed, the attacker can authenticate to the ASManager system, gaining administrative control over sensitive security infrastructure. This includes access to monitoring cameras, access cards, parking systems, employee and visitor data, and the ability to alter network and security configurations. The attacker can disrupt services, disconnect security devices, and clone access control data to facilitate further attacks. The exploit code is publicly available and tested on Windows 10 and Kali Linux environments, indicating that the vulnerability is well-understood and potentially exploitable in real-world scenarios. The root cause is improper memory handling, which leads to leakage of sensitive credentials stored in memory. The vulnerability is local and requires high privilege, but the impact of successful exploitation is severe due to the broad administrative access gained. The PoC and detailed exploitation steps are documented on GitHub, increasing the risk of widespread exploitation if mitigations are not applied.

For European organizations using GeoVision ASManager and associated security management software, this vulnerability poses a significant risk to physical and logical security. Organizations relying on GeoVision for access control, surveillance, and visitor management could face unauthorized access to critical infrastructure and sensitive personal data. The ability to manipulate access cards, employee records, and security configurations could lead to physical breaches, data theft, and operational disruptions. Disruption of monitoring cameras and access controls could blind security teams and allow malicious actors to operate undetected. The cloning and duplication of access control data could facilitate insider threats or external attackers gaining persistent unauthorized access. Given the integration of these systems into corporate security and facility management, the impact extends beyond IT to physical security domains. The requirement for local high privilege access means that initial compromise vectors such as phishing, malware, or insider threats could be leveraged to escalate privileges and exploit this vulnerability. The availability of public exploit code increases the urgency for European organizations to assess their exposure and implement mitigations promptly.

1. Immediate patching: Although no official patch links are provided, organizations should contact GeoVision for updates or apply any available patches addressing CVE-2025-26263. 2. Restrict local high privilege access: Limit administrative and system-level privileges on machines running ASManager to trusted personnel only. Implement strict access controls and monitoring to detect unauthorized privilege escalations. 3. Use endpoint protection: Deploy advanced endpoint detection and response (EDR) solutions to detect suspicious memory dumping or privilege escalation activities. 4. Network segmentation: Isolate systems running GeoVision software from general user networks to reduce the risk of lateral movement. 5. Credential hygiene: Regularly rotate credentials used by ASManager and related services to limit the window of opportunity for attackers. 6. Monitor logs and alerts: Enable detailed logging on ASManager and related systems and monitor for unusual authentication or configuration changes. 7. Employ application whitelisting and integrity checks to prevent unauthorized modification or execution of malicious code on systems hosting ASManager. 8. Conduct security awareness training to reduce the risk of initial compromise that could lead to privilege escalation. 9. Consider deploying multi-factor authentication (MFA) where possible to add an additional layer of security for administrative access.
