Ivanti Zero-Days: Your Gateway Just Became a Backdoor
Heads up, everyone! The cybersecurity world is once again buzzing, and not in a good way. Active exploitation of multiple Ivanti Connect Secure and Policy Secure vulnerabilities continues to hit organizations hard, turning trusted network access points into wide-open backdoors.[1]
These critical flaws, including CVE-2023-46805, CVE-2024-21887, CVE-2024-21888, CVE-2024-21893, and CVE-2024-22024, allow for authentication bypass, command injection, and server-side request forgery. The worst part? They’re being actively chained by multiple state-sponsored threat actors and cybercriminals to gain persistent access and execute arbitrary code on vulnerable appliances.[2]
So what? If your organization uses Ivanti Connect Secure VPN or Policy Secure network access control (NAC) solutions, you’re squarely in the crosshairs. These devices are often internet-facing, making them a prime target for initial access. Attackers are using these vulnerabilities to establish footholds, deploy web shells, and then move laterally into internal networks, leading to data exfiltration and further compromise. Ignoring these patches isn’t an option; it’s an invitation for disaster. Beyond patching, you need to hunt for signs of compromise, because many organizations were breached before they even knew about the fixes.[3]
This isn’t just another patch Tuesday; it’s a stark reminder that perimeter security isn’t just about firewalls. Your VPN and NAC appliances are critical entry points, and continuous vigilance, rapid patching, and proactive threat hunting are non-negotiable. Don’t let your gateway become a hacker’s express lane.
