Horizon Alert

Summary of the vulnerability and why it matters

A security vulnerability in Ivanti Connect Secure allows for privilege escalation to root, as it mishandles trusted configuration data. This issue has been actively exploited in the wild.

  • Issue allows unauthorized root access.
  • It is actively exploited by attackers.
  • Confirm relevance and assess exposure.

Attack Path

How an attacker could exploit the issue

An attacker with existing local access to a system can exploit a vulnerability in Ivanti Connect Secure by manipulating DSCache configuration data. This trust issue within the system allows the attacker to escalate their privileges to the highest level, root. The vulnerability has been actively exploited in the wild, indicating a significant risk to affected systems.

  • Requires local, authenticated access.
  • Manipulates DSCache configuration data.
  • Leads to root privilege escalation.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability, when chained with other supported exploits, could allow an attacker with some level of access to escalate privileges to root on the affected system, potentially impacting its integrity and availability.

  • System integrity and availability.
  • Local privilege escalation through chained exploits.
  • Unauthorized system control and disruption.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for Ivanti Connect Secure, likely including infrastructure or network security, should first confirm the presence and accessibility of this technology. Following confirmation, an assessment of business criticality and identification of the accountable owner are necessary steps before planning remediation actions based on the assessed risk.

  • Network/Security teams own the issue.
  • Verify external exposure and asset criticality.
  • Plan and coordinate remediation efforts.

Frequently asked questions

What is Ivanti Connect Secure?

Ivanti Connect Secure is a VPN gateway solution. Organizations deploy it at the network edge to provide remote users with secure access to internal private network resources and applications.

What does CWE-829 mean for CVE-2026-111357?

CWE-829 identifies a weakness where a system trusts data or components from an untrusted source. In this specific case, the software fails to properly validate DSCache configuration data, which allows an attacker to manipulate that data and gain unauthorized root-level access.

How is this vulnerability triggered?

An attacker must already have local, authenticated access to the system to exploit this bug. It cannot be triggered remotely by someone without existing access who simply sends a network request to the appliance.

Is my Ivanti Connect Secure instance at risk?

While the vulnerability itself requires local access, Halo Surface Signal notes that Ivanti Connect Secure is a VPN gateway designed to be internet-facing. This means if an attacker compromises the initial public-facing service, they could then leverage this local vulnerability to escalate their privileges.

What should I do if I run this software?

First, verify if your organization uses Ivanti Connect Secure 22.8R2.4. If identified, locate the system owner, assess the device's role in your network, and coordinate with your security team to prioritize patching based on the guidance provided by the vendor.
