Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability in Ivanti Endpoint Manager Mobile allows an unauthenticated attacker to execute arbitrary code remotely. Teams should pay attention because this could let unauthorized individuals gain control over your mobile devices.

  • Attackers can trigger code execution.
  • No prior access is needed.
  • Affects Ivanti EPMM mobile management.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can exploit this vulnerability by sending a crafted request to Ivanti EPMM's management interface. This would allow them to call any method within the application, potentially leading to complete system compromise.

  • Remote, unauthenticated attacker
  • Target Ivanti EPMM management interface
  • Exploit requires direct network access

Live Threat

Current exploitation, exposure, and threat context

This vulnerability allows for remote unauthenticated attackers to invoke arbitrary methods, which is a serious capability. Given the nature of the Ivanti EPMM product as a potential internet-facing management gateway, and the critical severity of this vulnerability, it is likely to be a target for exploitation. Attackers favor such vulnerabilities because they offer broad access and control without requiring any prior compromise or user interaction.

  • Remote unauthenticated code execution potential.
  • Exposed management interface makes it a target.
  • Ivanti EPMM is an edge service.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams should prioritize investigating Ivanti EPMM for versions prior to 12.6.1.1, 12.7.0.1, and 12.8.0.1 due to a critical vulnerability allowing unauthenticated remote code execution. Given the exposure of EPMM as a gateway service, actively exploitability is a high concern.

  • Update EPMM to 12.6.1.1, 12.7.0.1, or 12.8.0.1.
  • Block network access to EPMM if patching is delayed.
  • Monitor logs for unusual method invocations.
