Ivanti Under Siege: Your VPN is a Target!
Alright, folks, buckle up. The biggest cybersecurity news hitting the wires isn’t some fancy new AI exploit, but a good old-fashioned, deeply critical vulnerability in network infrastructure. Ivanti Connect Secure and Policy Secure gateways are under relentless attack, and if you’re running them, your perimeter is likely compromised or at severe risk.
This isn’t a new story, but it’s escalating rapidly. Multiple nation-state actors and cybercriminals are actively exploiting a chain of vulnerabilities to gain persistent access to corporate networks[1]. We’re talking about CVE-2023-46805 (authentication bypass), CVE-2024-21887 (command injection), CVE-2024-21888 (privilege escalation), CVE-2024-21893 (server-side request forgery), and the latest, CVE-2024-22024 (XML external entity injection) which allows for arbitrary file reading[2]. This cocktail of flaws grants attackers everything from unauthenticated remote code execution to bypassing authentication and reading sensitive files. CISA has even issued emergency directives, urging federal agencies to disconnect or patch these devices immediately[3].
So What?
Look, Ivanti VPNs are your front door to the internal network. If those are compromised, attackers are already inside, potentially moving laterally, exfiltrating data, or deploying ransomware. This isn’t just about applying a patch anymore; it’s about understanding the scope of potential compromise. Many organizations patched only to find out they were already exploited *before* the patch was available, or that the patch itself introduced new issues requiring further updates. Simply patching isn’t enough; you need to assume compromise, hunt for persistence mechanisms, and consider forensic analysis. This impacts anyone using these devices – from small businesses to major enterprises.
The bottom line is clear: if you’re using Ivanti Connect Secure or Policy Secure, you need to be on high alert. Patching is critical, but so is threat hunting and understanding the full scope of potential breach. The attackers aren’t waiting, and neither should you. Secure your perimeter, or watch it crumble.
