CVE-2019-11110

TITLE

Intel(R) CSME and TXE Authentication vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-013692

DESCRIPTION

Authentication bypass in the subsystem for Intel(R) CSME before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45, 13.0.10 and 14.0.10; Intel(R) TXE before versions 3.1.70 and 4.0.20 may allow a privileged user to potentially enable escalation of privilege via local access. Intel(R) CSME and TXE Contains an authentication vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Both Intel Converged Security and Management Engine (CSME) and Intel TXE are products of Intel Corporation of the United States. Intel Converged Security and Management Engine is a security management engine. Intel TXE is a trusted execution engine with hardware authentication function used in CPU (Central Processing Unit). Security vulnerabilities exist in subsystems in Intel CSME and Intel TXE. A local attacker could exploit this vulnerability to bypass authentication and elevate privileges. The following products and versions are affected: Intel CSME before 11.8.70, before 11.11.70, before 11.22.70, before 12.0.45, before 13.0.10, before 14.0.10; Intel TXE 3.1.70 Previous versions, versions before 4.0.20
