CVE-2025-4428 is a remote code execution vulnerability in the API component of Ivanti Endpoint Manager Mobile (EPMM). An insecure implementation of Hibernate Validator incorporates an attacker-controlled format parameter into a validation error message that is evaluated as a Java expression, allowing crafted API requests to execute arbitrary code and system commands. Affected branches include 11.12.0.4 and earlier, 12.3.0.1 and earlier, 12.4.0.1 and earlier, and 12.5.0.0 and earlier. Exploitation requires authentication when the vulnerability is used independently; chaining it with the authentication bypass CVE-2025-4427 enables unauthenticated remote code execution. The vulnerability has been exploited in the wild.

This repository contains a single Metasploit module targeting Ivanti Endpoint Manager Mobile (EPMM), formerly known as MobileIron Core. The exploit leverages an authentication bypass (CVE-2025-4427) and an expression language injection (CVE-2025-4428) to achieve unauthenticated remote code execution via a vulnerable web API endpoint. The main exploit file is written in Ruby and is structured as a standard Metasploit module, including auto-check capabilities and options for SSL and target URI configuration. The exploit works by sending a specially crafted payload to the '/mifs/rs/api/v2/featureusage' endpoint, injecting an expression that executes arbitrary Python code as the 'tomcat' user. The module includes a check method that attempts to execute the 'id' command to verify vulnerability. The payload is encoded in base64 and executed using Python on the target. The exploit is operational and provides remote code execution without authentication, making it a significant risk for affected systems.
This repository provides an operational exploit and detection tool for CVE-2025-4427 and CVE-2025-4428, targeting Ivanti Endpoint Manager Mobile (EPMM). The main exploit is implemented in 'CVE-2025-4428.py', a Python script that allows unauthenticated remote code execution by exploiting a Server-Side Template Injection (SSTI) vulnerability in a Java bean validator. The exploit works by sending a crafted HTTP GET request to vulnerable endpoints (such as '/api/v2/featureusage' and '/api/v2/featureusage_history') with a malicious 'format' parameter that triggers arbitrary command execution on the server. The script supports custom command execution, proxying, output redirection, and multi-shell support (bash/sh). The YAML file ('CVE-2025-4427.yaml') provides a nuclei-compatible detection template for automated scanning. The repository is well-structured, with clear documentation and operational exploit code, and is suitable for both detection and exploitation of the targeted vulnerabilities.

A CVSS 7.2 code-execution vulnerability in Ivanti EPMM. An attacker-controlled format value enters an error message evaluated as a Java expression, allowing system commands to execute. Chaining it with CVE-2025-4427 bypasses authentication. The full chain was publicly released and exploited on May 15, 2025; both vulnerabilities entered CISA KEV on May 19. Reported intrusions deployed Sliver implants and web shells and stole device information, LDAP credentials and Microsoft 365 access tokens. The article identifies EPMM updates fixing the chain and recommends restricting access to the affected API routes.
