Attackers Chain Three Ivanti Connect Secure Flaws to Gain Unauthenticated Root Access

By [email protected] (The Hacker News)

AI Summary

CISA added two Ivanti Connect Secure vulnerabilities to its KEV catalog following active exploitation: CVE-2026-111357 (CVSS 8.8), a missing authentication flaw, and a second flaw that together enable unauthenticated root access via chained exploitation. Defenders running ICS should treat patching as immediately mandatory given CISA's KEV designation and confirmed in-the-wild chaining. This continues the pattern of Ivanti VPN appliances serving as primary initial-access targets for sophisticated threat actors.
