Ivanti MobileIron Remote Code Execution Scanner

Ivanti MobileIron is a mobile device management (MDM) solution widely used in various organizations to manage and secure mobile data. It helps IT departments enforce policies, configure settings, and ensure compliance across multiple devices like smartphones and tablets. The software is pivotal in managing corporate devices remotely, enabling the secure transmission of corporate data. It is commonly utilized by companies that maintain a large fleet of mobile devices. MobileIron is known for its flexibility and support for a wide range of device types, making it an attractive choice for industries such as education, healthcare, and finance where data security is paramount. Its integration capabilities provide deep management control over both company-issued and BYOD devices.

This Remote Code Execution (RCE) vulnerability involves the exploitation of log message manipulation within the Apache Log4j2 library. The issue stems from JNDI features used in configuration, log messages, and parameters that do not properly neutralize attacker-controlled input. By manipulating these inputs, an attacker can use the JNDI lookup functionality to trigger execution of malicious code. This vulnerability affects the Apache Log4j2 library and arises when message lookup substitution is enabled, allowing untrusted inputs to be exploited. Once exploited, it enables an attacker to remotely execute arbitrary code on the server, potentially compromising the system's integrity and confidentiality. The implications are widespread, given that affected versions were widely used prior to the discovery and patching of this vulnerability.

The vulnerability exploits the endpoint handling log messages and parameters in Apache Log4j2. Specifically, the parameter 'j_username' is vulnerable to injection where an attacker could inject a malicious JNDI string. This crafted string can redirect the lookup to an attacker-controlled LDAP server. The malicious code retrieved from this LDAP server is then executed, resulting in a successful remote code execution. The vulnerability is particularly concerning due to its low exploitation complexity and the ability of an attacker to achieve full system control by manipulating log entries. The nexus of the flaw is bound within the JNDI implementation which accepts input without sufficient validation, thus enabling the attacker's payload to be processed.

If exploited, this vulnerability may allow attackers to execute arbitrary code on the targeted system, gaining unauthorized access and control over sensitive information. It can lead to data exfiltration, unauthorized manipulation of data, or a complete system takeover. In a business context, exploitation might result in data breaches, infringement of data privacy regulations, and substantial financial damage due to loss of intellectual property or sensitive customer information. Additionally, if an attacker gains control, they might deploy malware or ransomware, further compromising the organization’s operations. This highlights the critical need for immediate remediation to prevent potential catastrophic impacts.
