Ivanti EPMM Flaws Enable Auth Bypass and RCE

Overview of the Ivanti EPMM Vulnerabilities

Ivanti has disclosed two high risk security vulnerabilities affecting Ivanti Endpoint Manager Mobile (EPMM), tracked as CVE-2026-1281 and CVE-2026-1340. These flaws impact the core management interface used to administer mobile devices across enterprise environments. According to the advisory published by Ivanti, successful exploitation could allow attackers to bypass authentication controls and execute arbitrary code on affected systems.

The vulnerabilities highlight continued risk in externally exposed device management platforms.

Affected Component and Attack Surface

Ivanti EPMM is commonly deployed as an internet facing service to manage smartphones, tablets, and endpoints. The vulnerabilities reside in backend request handling logic tied to authentication and input validation mechanisms.

Because EPMM servers often have high privilege access to enrolled devices, any compromise of the platform presents a significant security concern. Systems exposed to the internet are at the highest risk, particularly those without network level access restrictions.

CVE-2026-1281 Authentication Bypass

CVE-2026-1281 is an authentication bypass vulnerability that allows a remote, unauthenticated attacker to access restricted application functionality. The flaw stems from improper validation of user supplied input during request processing.

An attacker can craft specific requests that bypass authentication checks, gaining unauthorized access to administrative endpoints. Once access is achieved, the attacker may interact with sensitive configuration settings or chain the vulnerability with other flaws for deeper compromise.

This issue reduces the effectiveness of perimeter based defenses and increases exposure for publicly accessible deployments.

CVE-2026-1340 Remote Code Execution

CVE-2026-1340 is a remote code execution vulnerability that can be exploited after initial access is obtained. The flaw allows malicious input to be processed in a way that results in execution of attacker controlled code on the EPMM server.

When combined with the authentication bypass, this vulnerability enables a full compromise scenario. Attackers can execute commands with the privileges of the EPMM service, potentially accessing backend databases, encryption keys, or connected management services.

Exploitation Risk and Impact

Exploitation of these vulnerabilities could lead to:

• Full takeover of the EPMM management server
• Exposure of sensitive enterprise and device data
• Ability to issue malicious commands to enrolled mobile devices
• Lateral movement into internal enterprise networks

Given the role EPMM plays in enterprise security operations, successful exploitation may have cascading effects beyond the initial system.

Mitigation and Defensive Guidance

Ivanti has released patches addressing both vulnerabilities and strongly advises administrators to update affected systems immediately. Organizations should also restrict EPMM access to trusted networks, review server logs for anomalous activity, and rotate credentials following patch deployment.

This disclosure reinforces the importance of rapid patch management and continuous monitoring for critical enterprise mobility infrastructure.
