Ivanti Connect Secure authentication bypass lets remote attackers run commands
Unauthenticated remote attackers can bypass authentication in Ivanti Connect Secure and execute arbitrary commands. CISA confirms active exploitation. Apply Ivanti's guidance now and check exposed appliances for signs of compromise.
In plain terms
Ivanti Connect Secure is a VPN gateway, an appliance that lets employees connect securely to an internal company network from outside. This flaw lets an attacker trick the appliance into accepting them as legitimate without valid credentials. This is called an authentication bypass by spoofing, meaning the attacker fakes an identity or trusted source. Once past that check, the attacker can run their own commands on the device.
These gateways usually face the internet and sit at the edge of the corporate network, so a compromise can give an outsider a foothold inside. CISA has confirmed real-world attacks. Any organisation running the affected versions should treat this as urgent.
