Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability in Ivanti EPMM could allow an attacker to impersonate mobile device management servers and obtain legitimate client certificates. This is a serious concern because it undermines trust in your mobile infrastructure and could lead to further compromise of sensitive data.
- Attacker can impersonate servers.
- Legitimate certificates can be stolen.
- Impacts mobile device management.
Attack Path
How an attacker could exploit the issue
An unauthenticated remote attacker could exploit this flaw to impersonate registered Sentry hosts. By doing so, they can obtain valid CA-signed client certificates, which could then be used to gain unauthorized access to sensitive resources or to further compromise the network.
- Network accessible endpoint.
- No authentication required.
- Obtain valid client certificates.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in Ivanti EPMM allows unauthenticated attackers to impersonate Sentry hosts and obtain valid client certificates. Such a capability is highly attractive to attackers as it could enable further lateral movement within an organization's network or the circumvention of security controls by presenting as a legitimate device. The potential for broad impact and ease of exploitation makes this a concerning vulnerability.
- Remote, unauthenticated attack vector.
- Can bypass authentication and gain trust.
- Directly impacts device management infrastructure.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize patching Ivanti EPMM to address the critical vulnerability that allows unauthenticated remote attackers to impersonate Sentry hosts. This impersonation can lead to the issuance of forged client certificates, enabling attackers to bypass authentication and potentially access sensitive resources. If patching is not immediately feasible, implement network-level controls to restrict access to the EPMM service.
- Update to version 12.6.1.1, 12.7.0.1, or 12.8.0.1.
- Restrict network access to EPMM.
- Monitor for anomalous Sentry host behavior.
