TITLE

Raspberry Pi 3 module B+ Vulnerabilities related to authorization, permissions, and access control

Trust: 0.8

sources: JVNDB: JVNDB-2018-015231

DESCRIPTION

The ARM-based hardware debugging feature on Raspberry Pi 3 module B+ and possibly other devices allows non-secure EL1 code to read/write any EL3 (the highest privilege level in ARMv8) memory/register via inter-processor debugging. With a debug host processor A running in non-secure EL1 and a debug target processor B running in any privilege level, the debugging feature allows A to halt B and promote B to any privilege level. As a debug host, A has full control of B even if B owns a higher privilege level than A. Accordingly, A can read/write any EL3 memory/register via B. Also, with this memory access, A can execute arbitrary code in EL3. Raspberry Pi 3 module B+ Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Raspberry Pi 3 module B+ is an embedded system development board. The vulnerability stems from the lack of effective permissions and access control measures in network systems or products
