CVE-2025-31513 is a privilege escalation vulnerability identified in AlertEnterprise Guardian version 4.1.14.2.2.1. The flaw arises from improper access control in the Request Building Access requestSubmit API call, specifically via the IsAdminApprover parameter. An attacker can exploit this parameter to elevate their privileges to administrator level without requiring prior authentication or user interaction. This vulnerability is classified under CWE-266, which pertains to improper privileges management. The vendor has addressed this issue by releasing patched builds starting from various build numbers across multiple minor versions, including 4.1.12.2.1.19 and later. The CVSS v3.1 base score is 6.5, indicating a medium severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N. This means the vulnerability is remotely exploitable over the network without any privileges or user interaction, impacting confidentiality and integrity but not availability. No known exploits are reported in the wild as of the publication date, July 22, 2025. The vulnerability allows unauthorized users to gain administrative privileges, potentially leading to unauthorized access to sensitive data and system controls within the AlertEnterprise Guardian environment. Given that AlertEnterprise Guardian is a security and compliance management platform often used in enterprise environments to control physical and logical access, exploitation could undermine organizational security policies and controls.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on AlertEnterprise Guardian for access control and compliance management. Unauthorized privilege escalation to administrator level can lead to unauthorized access to sensitive physical and logical security controls, potentially allowing attackers to bypass security policies, access confidential data, or manipulate access logs. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), and operational disruptions. Organizations in sectors with stringent security requirements such as finance, healthcare, critical infrastructure, and government are particularly at risk. The ability to exploit this vulnerability remotely without authentication increases the threat surface, making it easier for attackers to compromise systems from outside the network perimeter. The lack of known exploits currently provides a window for mitigation before widespread exploitation occurs, but the medium severity score indicates that the vulnerability should be addressed promptly to avoid escalation.

European organizations using AlertEnterprise Guardian should immediately verify their current software build version against the vendor's patched build numbers and upgrade to a version equal to or greater than the specified builds (e.g., 4.1.12.2.1.19 or later). It is critical to apply these updates as soon as possible to eliminate the privilege escalation vector. Additionally, organizations should audit access logs and monitor for unusual API calls, particularly those involving the Request Building Access requestSubmit API and the IsAdminApprover parameter. Implement network segmentation and restrict API access to trusted internal networks or VPNs to reduce exposure. Employ strict role-based access controls and multi-factor authentication for administrative accounts to mitigate the impact of any potential compromise. Regularly review and update security policies related to API usage and access control management. Finally, conduct penetration testing and vulnerability assessments focused on AlertEnterprise Guardian deployments to ensure no residual vulnerabilities remain.
