CVE-2025-4428 is a high-severity vulnerability classified under CWE-94 (Improper Control of Generation of Code, commonly known as Code Injection) affecting Ivanti Endpoint Manager Mobile versions 12.5.0.0 and prior. This vulnerability resides in the API component of the product and allows authenticated attackers to execute arbitrary code remotely by sending specially crafted API requests. The vulnerability enables remote code execution (RCE), which means an attacker who has valid credentials can leverage this flaw to run malicious code on the affected system with the privileges of the Ivanti Endpoint Manager Mobile service. The CVSS v3.1 base score of 7.2 reflects a high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and requiring high privileges but no user interaction. The vulnerability affects unspecified platforms, indicating that all supported operating systems running the vulnerable version of the product may be at risk. Although no known exploits are currently reported in the wild, the presence of this vulnerability in a widely used endpoint management solution poses a significant risk, especially in environments where Ivanti Endpoint Manager Mobile is deployed to manage mobile devices and enforce security policies. The lack of published patches at the time of disclosure increases the urgency for organizations to implement compensating controls and monitor for suspicious activity targeting the API component.

For European organizations, the impact of this vulnerability can be substantial. Ivanti Endpoint Manager Mobile is used to manage and secure mobile endpoints, which are critical for enterprise mobility, remote work, and compliance with data protection regulations such as GDPR. Successful exploitation could lead to unauthorized access to sensitive corporate data, disruption of endpoint management services, and potential lateral movement within the network. This could result in data breaches, loss of data integrity, and operational downtime. Given the high privileges required, attackers could manipulate device configurations, deploy malware, or exfiltrate confidential information. The disruption of endpoint management capabilities could also hinder incident response and remediation efforts. European organizations in sectors such as finance, healthcare, government, and critical infrastructure, which rely heavily on endpoint security and compliance, would face increased risks of regulatory penalties and reputational damage if this vulnerability is exploited.

1. Immediate mitigation should include restricting access to the Ivanti Endpoint Manager Mobile API to trusted network segments and enforcing strict network-level access controls such as IP whitelisting and VPN-only access. 2. Implement multi-factor authentication (MFA) for all accounts with access to the management API to reduce the risk of credential compromise. 3. Monitor API logs and network traffic for unusual or suspicious requests that could indicate exploitation attempts, focusing on anomalous patterns or unexpected API calls. 4. Apply the principle of least privilege by ensuring that only necessary accounts have high-level privileges required to interact with the API. 5. Until an official patch is released, consider deploying Web Application Firewalls (WAFs) or API gateways with custom rules to detect and block potentially malicious payloads targeting code injection vectors. 6. Regularly review and update endpoint management policies and configurations to minimize attack surface exposure. 7. Prepare incident response plans specifically addressing potential exploitation of this vulnerability, including rapid isolation and forensic analysis procedures.
