Detailsinfo

A vulnerability was found in Pulse Policy Secure and Pulse Connect Secure up to 9.1R7. It has been classified as critical. Affected is some unknown processing of the component Kernel Boot Handler. The manipulation as part of a Parameter leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.)

The weakness was presented 07/27/2020 (Website). The advisory is available at kb.pulsesecure.net. This vulnerability is traded as CVE-2020-12880 since 05/15/2020. The exploitability is told to be difficult. Local access is required to approach this attack. The exploitation doesn't require any form of authentication.
