Your VPN Isn’t Safe: Ivanti Zero-Days Under Relentless Attack!
Alright folks, let’s cut to the chase: Ivanti Connect Secure VPN appliances are under a sustained, brutal assault. Multiple critical vulnerabilities are being actively exploited in the wild, giving attackers a direct highway into corporate networks.
Specifically, we’re talking about a chain of vulnerabilities including CVE-2023-46805 (authentication bypass), CVE-2024-21887 (command injection), CVE-2024-21888 (privilege escalation), and CVE-2024-21893 (server-side request forgery). These aren’t theoretical; state-sponsored groups like Volt Typhoon have been leveraging these flaws for months, deploying web shells and backdoors to maintain persistence and exfiltrate data. Mandiant and CISA have been tracking these exploits closely, urging immediate patching.[1]
So what does this mean for you, the dev, the ops engineer, the security lead? Simple: if your organization uses Ivanti Connect Secure, you are a prime target. These aren’t just theoretical exploits; they’re being used to breach networks globally, leading to data theft, ransomware, and long-term persistence. This isn’t just about patching; it’s about incident response, threat hunting, and assuming compromise. Even if you’ve patched, you need to hunt for signs of prior compromise using the provided Indicators of Compromise.[2]
This whole Ivanti saga is a stark reminder: perimeter security is dead, and VPNs, while necessary, are massive attack surfaces. Trust nothing, verify everything, and for crying out loud, patch immediately and then assume you’re already compromised.
