CVE-2023-35082
Overview
This vulnerability is an authentication bypass affecting Ivanti Endpoint Manager Mobile (EPMM) versions 11.10 and earlier. The root cause lies in the permissive configuration of the mifs web application’s security filter chain, which fails to enforce proper authentication checks on certain API endpoints. This flaw allows unauthorized access to restricted application functionality by circumventing the intended authentication mechanism.
Vulnerability Description
An authentication bypass vulnerability in Ivanti EPMM 11.10 and older, allows unauthorized users to access restricted functionality or resources of the application without proper authentication. This vulnerability is unique to CVE-2023-35078 announced earlier.
Impact
An attacker can remotely access and manipulate restricted resources and functionality within Ivanti EPMM without any authentication or user interaction. This unauthorized access enables exposure of sensitive data and the ability to perform malicious actions within the application context. The lack of authentication barriers facilitates potential full compromise of the management platform, risking data breaches and operational disruption in enterprise mobile device management environments.
Solution
Ivanti has published security advisories addressing this authentication bypass in Endpoint Manager Mobile (EPMM) versions 11.10 and earlier. Users should apply the vendor-released patches as detailed in Ivanti’s official advisory at https://forums.ivanti.com/s/article/CVE-2023-35082-Remote-Unauthenticated-API-Access-Vulnerability-in-MobileIron-Core-11-2-and-older?language=en_US. Upgrading to fixed versions beyond 11.10 is recommended. No specific workarounds are provided; patching is the primary mitigation step.

Full Analysis
The authentication bypass vulnerability in Ivanti Endpoint Manager Mobile (EPMM) versions 11.10 and earlier poses a significant risk to organizations relying on this platform for mobile device management. This flaw allows unauthorized users to gain access to restricted functionalities and resources within the application without undergoing the necessary authentication processes. The underlying issue stems from improper validation of user credentials, which can be exploited to circumvent security measures designed to protect sensitive data and administrative controls. Such vulnerabilities are particularly concerning in environments where mobile devices are integral to business operations, as they can lead to unauthorized access to corporate networks and sensitive information.
Attack vectors for this vulnerability are varied, with the potential for exploitation occurring through several means. An attacker could leverage social engineering tactics to gain initial access to the application, or they might exploit weaknesses in the application's session management. Once inside, they can perform actions that would typically require elevated privileges, such as accessing confidential data, modifying configurations, or deploying malicious applications to managed devices. The ease of exploitation, combined with the high level of access granted, makes this vulnerability particularly attractive to malicious actors, including cybercriminals and state-sponsored hackers.
The real-world impact of this authentication bypass vulnerability can be profound. Organizations that fail to address this issue may face significant business risks, including data breaches, loss of intellectual property, and damage to their reputation. The potential for unauthorized access to sensitive corporate data can lead to regulatory non-compliance, resulting in hefty fines and legal repercussions. Furthermore, the operational disruptions caused by a successful exploit can lead to financial losses and a decline in customer trust. Given the increasing reliance on mobile devices for business operations, the ramifications of such a vulnerability can extend beyond immediate financial impacts to long-term strategic challenges.
To effectively detect and mitigate this vulnerability, organizations should adopt a multi-faceted approach. Regular security assessments and penetration testing can help identify weaknesses in the application and its configuration. Implementing robust logging and monitoring solutions will enable organizations to detect unusual access patterns or unauthorized attempts to exploit the vulnerability. Additionally, organizations should prioritize applying security patches and updates provided by Ivanti, ensuring that their systems are running the latest, most secure versions of the software. Employee training on security best practices can also reduce the risk of social engineering attacks that may facilitate exploitation.
In conclusion, the authentication bypass vulnerability in Ivanti EPMM represents a critical security concern that organizations must address promptly. The potential for unauthorized access to sensitive resources poses significant risks, including data breaches and regulatory penalties. By implementing comprehensive detection and mitigation strategies, organizations can protect themselves against the exploitation of this vulnerability and safeguard their mobile device management environments. As cyber threats continue to evolve, maintaining a proactive security posture is essential for minimizing risk and ensuring the integrity of business operations.
CSURFACE threat intelligence has identified a recalibration in the severity rating of CVE-2023-35082, with the CVSS score elevated from 9.8 to the maximum of 10.0. This adjustment reflects a refined understanding of the vulnerability’s impact, underscoring its critical nature and the absolute potential for unauthorized access without authentication. Concurrently, our telemetry indicates a significant reduction in detection activity related to this vulnerability, suggesting either a temporary decline in exploitation attempts or improved defensive measures in affected environments. Despite this downturn, the vulnerability remains prominently featured in the Known Exploited Vulnerabilities (KEV) catalog, with confirmed ransomware associations, notably involving the 0apt group. The availability of new proof-of-concept exploits further emphasizes the persistent risk and the ease with which threat actors could weaponize this flaw. The elevated CVSS score combined with stable EPSS metrics and ransomware linkages necessitates maintaining a high threat level classification. Defenders should remain vigilant as the potential for impactful exploitation persists, particularly given the criticality of the affected Ivanti EPMM platforms in enterprise mobile device management.
