TITLE

Intel(R) CSME and TXE Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-013699

DESCRIPTION

Insufficient input validation 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, information disclosure or denial of service via local access. Intel(R) CSME and TXE Contains an input validation 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). A security vulnerability exists in a subsystem in Intel CSME and Intel TXE due to insufficient input validation. A local attacker could exploit this vulnerability to elevate privileges, disclose information or cause a denial of service. 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
