Description

This security bulletin contains information about 8 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-0594)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a boundary condition in IPv6 subsystem. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system, leading to privilege escalation.

Note: This vulnerability affects the following versions of Intel AMT and ISM:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

2) Use-after-free (CVE-ID: CVE-2020-0595)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in IPv6 subsystem. A remote attacker can gain elevated privileges on the target system.

Note: This vulnerability affects the following versions of Intel AMT and ISM:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

3) Input validation error (CVE-ID: CVE-2020-0538)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in subsystem. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Note: This vulnerability affects the following versions of Intel AMT:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

4) Information disclosure (CVE-ID: CVE-2020-0596)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to improper input validation in DHCPv6 subsystem. A remote attacker can gain unauthorized access to sensitive information on the system.

Note: This vulnerability affects the following versions of Intel AMT and ISM:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

5) Input validation error (CVE-ID: CVE-2020-0532)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to insufficient validation of user-supplied input in subsystem. An attacker with physical access can pass specially crafted input to the application and perform a denial of service (DoS) attack or disclose sensitive information on the target system.

Note: This vulnerability affects the following versions of Intel AMT:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

6) Information disclosure (CVE-ID: CVE-2020-0531)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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

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

Note: This vulnerability affects the following versions of Intel AMT:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

7) Insufficiently protected credentials (CVE-ID: CVE-2020-0540)

CWE-ID: CWE-522 - Insufficiently Protected Credentials

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to sensitive information on the system. 

The vulnerability exists due to insufficiently protected credentials. A remote attacker can gain unauthorized access to sensitive information on the target system.

Note: This vulnerability affects the following versions of Intel AMT:

  • 11.0 through 11.8.76
  • 11.10 through 11.11.76
  • 11.20 through 11.22.76
  • 12.0 through 12.0.63

8) Input validation error (CVE-ID: CVE-2020-0537)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
