AI Breakdown
What it is
CVE-2026-111357 is a flaw in Ivanti Connect Secure where the system improperly trusts internal configuration data without proper authentication checks. This allows an attacker who already has local authenticated access to escalate their permissions to full root control. Threat actors can also chain this weakness with CVE-2026-104935 and CVE-2026-118527 to achieve broader compromise.
Why it matters
This flaw is actively exploited in the wild, allowing attackers to take over critical network access appliances. Although its use in ransomware campaigns is currently unknown, granting an attacker root privileges severely undermines network security. Organizations must treat this as urgent due to confirmed active exploitation and chaining potential.
Recommended action
Apply vendor-provided mitigations and security updates immediately, adhering to CISA risk-based update guidance. Perform recommended forensic triage procedures to ensure affected appliances have not already been compromised. If mitigations or updates are unavailable, isolate or discontinue use of the product to prevent exposure.
