Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Path traversal (CVE-ID: CVE-2020-0539)

The vulnerability allows a local user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in subsystem for Intel(R) DAL software for Intel(R) CSME. A local user can send a specially crafted HTTP request and cause a denial of service condition on the system.

Note: This vulnerability affects the following versions of Intel CSME and TXE:

CSME:

  • 11.0 through 11.8.76
  • 11.10 through 11.12.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63
  • 13.0.31 and 14.0.32
TXE:

  • 3.0 through 3.1.70
  • 4.0 through 4.0.20



2) Integer overflow (CVE-ID: CVE-2020-0545)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to integer overflow in subsystem. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.

Note: This vulnerability affects the following versions of Intel CSME, TXE and SPS:

CSME:

  • 11.0 through 11.8.76
  • 11.20 through 11.22.76
  • 11.10 through 11.12.76
TXE:

  • 3.0 through 3.1.70
  • 4.0 through 4.0.20
SPS:

  • SPS_E5_04.00.00.000.0 through SPS_E5_04.01.04.379.0
  • SPS_SoC-X_04.00.00.000.0 through SPS_SoC-X_04.00.04.127.0
  • SPS_SoC-A_04.00.00.000.0 through SPS_SoC-A_04.00.04.210.0
  • SPS_E3_04.00.00.000.0 through SPS_E3_04.01.04.103.0
  • SPS_E3_04.08.00.000.0 through SPS_E3_04.08.04.065.0


3) Information disclosure (CVE-ID: CVE-2020-0536)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to improper input validation in the DAL subsystem. A remote attacker can gain unauthorized access to sensitive information on the system.

Note: This vulnerability affects the following versions of Intel CSME and TXE:

CSME:
  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63
TXE:
  • 3.0 through 3.1.70
  • 4.0 through 4.0.20

4) Improper access control (CVE-ID: CVE-2020-0566)

The vulnerability allows a local attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in subsystem. An attacker with physical access can bypass implemented security restrictions and gain unauthorized access to the application.

Note: This vulnerability affects the following versions of Intel TXE:
  • 3.0 through 3.1.70
  • 4.0 through 4.0.20
