Technical ContextAI · show details

An issue was discovered in Pulse Policy Secure (PPS) and Pulse Connect Secure (PCS) Virtual Appliance before 9.1R8. By manipulating a certain kernel boot parameter, it can be tricked into dropping into a root shell in a pre-install phase where the entire source code of the appliance is available and can be retrieved. (The source code is otherwise inaccessible because the appliance has its hard disks encrypted, and no root shell is available during normal operation.) Affected products include: Ivanti Connect Secure, Pulsesecure Pulse Connect Secure, Ivanti Policy Secure, Pulsesecure Pulse Policy Secure. Version information: before 9.1.
