CVE-2023-35082

Comprehensive Technical Analysis of CVE-2023-35082

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-35082 CISA Vulnerability Name: Ivanti Endpoint Manager Mobile (EPMM) and MobileIron Core Authentication Bypass Vulnerability CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthorized access to restricted functionality or resources, which can lead to significant security breaches. The vulnerability allows attackers to bypass authentication mechanisms, thereby gaining unauthorized access to sensitive data and functionalities within the Ivanti EPMM and MobileIron Core systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Unauthenticated API Access: Attackers can exploit this vulnerability by sending specially crafted API requests to the affected systems. These requests can bypass the authentication mechanisms, allowing unauthorized access to restricted resources.
• Network-Based Attacks: Since the vulnerability can be exploited remotely, attackers can target the affected systems over the network, potentially from anywhere in the world.

Exploitation Methods:

• API Manipulation: Attackers can manipulate API endpoints to bypass authentication checks. This can be done by crafting requests that exploit weaknesses in the authentication logic.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable systems and exploit the vulnerability en masse.

3. Affected Systems and Software Versions

Affected Systems:

• Ivanti Endpoint Manager Mobile (EPMM) versions 11.10 and older
• MobileIron Core versions 11.2 and older

Note: It is crucial to identify all instances of these software versions within an organization's infrastructure to assess the scope of the vulnerability.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest patches and updates provided by Ivanti. Ensure that all affected systems are updated to versions that address this vulnerability.
• Network Segmentation: Implement network segmentation to isolate critical systems and reduce the attack surface.
