CVE-2024-38653 Scanner

Ivanti Avalanche SmartDeviceServer is a device management software widely used in enterprise environments to manage and configure mobile devices and other endpoints. It helps IT administrators streamline operations and enforce security policies across connected devices. This software is commonly used in industries such as retail, logistics, and healthcare to maintain efficiency and compliance. Ivanti provides both on-premises and cloud-based deployment options for flexibility. With its centralized management capabilities, it reduces overhead and improves operational control.

This vulnerability, identified as CVE-2024-38653, arises from improper processing of XML input in the Ivanti Avalanche SmartDeviceServer. Specifically, it allows attackers to exploit XML External Entities (XXE) to access sensitive files on the affected system. An unauthenticated remote attacker can send specially crafted XML payloads to trigger this vulnerability. If successfully exploited, attackers can read arbitrary files, potentially exposing critical information.

The XXE vulnerability affects the endpoint /mdm/checkin in the Ivanti Avalanche SmartDeviceServer. Attackers can inject malicious XML payloads containing external entity declarations, which reference arbitrary files on the server. The Content-Type header must be set to application/xml to craft an exploit request. Upon processing the payload, the server attempts to resolve the external entities, exposing sensitive files or system configurations. This flaw results from improper validation of XML input, leaving the system vulnerable to unauthorized file access.

Possible Effects:

• Unauthorized access to sensitive server files, potentially exposing credentials or configuration details.
• Increased risk of further attacks, such as privilege escalation or lateral movement within the network.
• Compromise of data integrity, confidentiality, and privacy on affected systems.
• Reputation damage and compliance violations for organizations using the vulnerable software.
