CVE-2025-0325 is a medium-severity vulnerability identified in Axis Communications AB's AXIS OS, affecting multiple versions ranging from 6.50.0 through 12.0.0. The vulnerability arises from improper validation of input parameters in the Guard Tour VAPIX API, specifically allowing arbitrary values to be passed and incorrectly processed. This flaw enables an attacker with limited privileges (requires low privileges but no user interaction) to block access to the guard tour configuration page within the web interface of the Axis device. The Guard Tour feature is typically used in security cameras and surveillance devices to automate patrol routes or monitoring sequences. The vulnerability is categorized under CWE-1287 (Improper Validation of Specified Type of Input) and CWE-628 (Incorrect Handling of Exceptional Conditions). The CVSS v3.1 base score is 4.3, reflecting a network attack vector with low complexity, requiring privileges but no user interaction, and resulting in availability impact only (denial of access to configuration). There are no known exploits in the wild at the time of publication, and no patches have been linked yet. This vulnerability does not affect confidentiality or integrity but can disrupt availability by preventing administrators from accessing and managing guard tour configurations, potentially degrading surveillance effectiveness and operational security management.

For European organizations, particularly those relying on Axis Communications' surveillance devices for physical security and monitoring, this vulnerability could lead to operational disruptions. Blocking access to the guard tour configuration page can prevent security administrators from updating or managing patrol routes, potentially leading to gaps in surveillance coverage or delayed response to incidents. This is especially critical in sectors such as transportation hubs, critical infrastructure, government facilities, and large enterprises where continuous monitoring is essential. While the vulnerability does not directly compromise data confidentiality or integrity, the denial of availability of configuration management could indirectly increase risk exposure by reducing the effectiveness of physical security controls. Additionally, since exploitation requires some level of privilege, insider threats or compromised low-privilege accounts could leverage this vulnerability to degrade security posture. The lack of known exploits currently reduces immediate risk, but the widespread use of Axis devices in Europe makes timely mitigation important to prevent future exploitation.

To mitigate CVE-2025-0325, European organizations should first verify if their Axis devices run affected AXIS OS versions (6.50.0 through 12.0.0). Until a patch is released, organizations should restrict access to the Guard Tour VAPIX API and the web interface to trusted administrators only, employing network segmentation and firewall rules to limit exposure. Implement strict access controls and monitor logs for unusual API calls or failed access attempts to the guard tour configuration page. Employ multi-factor authentication for administrative access to reduce the risk of privilege misuse. Regularly audit user privileges to ensure minimal necessary access. Once Axis Communications releases a security patch, organizations should prioritize prompt deployment. Additionally, consider implementing compensating controls such as out-of-band configuration management or backup configurations to restore guard tour settings if access is blocked. Security teams should stay informed via official Axis communications and vulnerability databases for updates or exploit reports.
