Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

CVE-2023-35078 is a critical authentication bypass vulnerability in Ivanti Endpoint Manager Mobile (EPMM) that allows attackers to access restricted application functionality and resources without any authentication. The vulnerability has a CVSS score of 10, indicating maximum severity, with complete compromise of confidentiality, integrity, and availability possible. No user interaction or privileges are required to exploit this flaw, and it affects all versions of the product. While no public exploits are currently known, the vulnerability poses a significant risk to organizations using Ivanti EPMM for mobile device management. European organizations relying on this product for endpoint security could face unauthorized access, data breaches, and operational disruption. Immediate patching or mitigation is critical, though no patches are currently listed. Organizations should implement network-level restrictions, monitor for anomalous access, and consider compensating controls until a fix is available. Countries with high adoption of Ivanti EPMM and critical infrastructure reliance on mobile device management, such as Germany, the UK, France, and the Netherlands, are most at risk.

Impact

For European organizations, this vulnerability poses a significant threat to the security and operational integrity of mobile device management infrastructures. Unauthorized access to Ivanti EPMM could allow attackers to manipulate device policies, access confidential corporate data, and potentially deploy malware or ransomware across managed devices. This could lead to widespread data breaches, regulatory non-compliance (especially under GDPR), and operational disruptions. Critical sectors such as finance, healthcare, government, and telecommunications that rely heavily on mobile device management for secure operations are at heightened risk. The ability to bypass authentication without any user interaction or privileges means that attackers can exploit this vulnerability remotely and stealthily, increasing the likelihood of targeted attacks or opportunistic exploitation. The potential for full compromise of confidentiality, integrity, and availability underscores the critical impact on business continuity and data protection obligations within European jurisdictions.

Mitigation

Given the absence of an official patch at the time of disclosure, European organizations should immediately implement compensating controls to mitigate risk. These include restricting network access to the Ivanti EPMM management interface to trusted IP addresses and VPN-only access to reduce exposure. Implement strict firewall rules and segmentation to isolate the management server from general network traffic. Enable and enhance logging and monitoring on the EPMM server to detect anomalous access patterns or unauthorized attempts. Conduct thorough audits of user accounts and permissions within the EPMM environment to minimize potential attack surfaces. Where possible, temporarily disable non-essential functionalities or services within the EPMM platform that could be exploited. Organizations should also engage with Ivanti support to obtain timelines for patches and apply updates promptly once available. Additionally, educating security teams about this vulnerability and preparing incident response plans specific to EPMM compromise scenarios will improve readiness. Finally, consider deploying endpoint detection and response (EDR) solutions on managed devices to detect suspicious activities stemming from potential EPMM exploitation.

Summary

CVE-2023-35078 is an authentication bypass vulnerability identified in Ivanti Endpoint Manager Mobile (EPMM), a widely used mobile device management (MDM) solution. The vulnerability allows an unauthenticated attacker to bypass authentication mechanisms and gain unauthorized access to restricted functionalities and resources within the application. This flaw is categorized under CWE-287 (Improper Authentication), indicating that the system fails to properly verify user credentials before granting access. The CVSS v3.0 base score of 10.0 reflects the critical nature of this vulnerability, with attack vector being network-based (AV:N), requiring no privileges (PR:N), no user interaction (UI:N), and impacting confidentiality, integrity, and availability at a high level (C:H/I:H/A:H). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. Exploitation could lead to full compromise of the MDM environment, allowing attackers to manipulate device configurations, access sensitive data, deploy malicious payloads, or disrupt mobile device operations. Although no known exploits have been reported in the wild, the severity and ease of exploitation make this a high-priority issue. The lack of specified affected versions and absence of published patches at the time of disclosure increases the urgency for organizations to implement interim mitigations and monitor for suspicious activity. Ivanti EPMM is commonly deployed in enterprise environments to manage and secure mobile endpoints, making this vulnerability particularly impactful for organizations relying on it for endpoint security and compliance.
