Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper Authentication (CVE-ID: CVE-2019-13531)

CWE-ID: CWE-287 - Improper Authentication

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


The vulnerability allows a local attacker to bypass authentication process.

The vulnerability exists due to an error in the RFID security mechanism used for authentication between the FT10/LS10 Energy Platform and instruments. An attacker with physical access to the device can connect inauthentic instruments to the generator, bypass authentication process and gain unauthorized access to the application.


2) Protection Mechanism Failure (CVE-ID: CVE-2019-13535)

CWE-ID: CWE-693 - Protection Mechanism Failure

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


The vulnerability allows a local attacker to bypass certain restrictions.

The vulnerability exists due to the RFID security mechanism does not apply read protection. An attacker with physical access to the device can gain full read access of the RFID security mechanism data.

3) Use of hard-coded credentials (CVE-ID: CVE-2019-13543)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

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


The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded credentials in application code. A remote unauthenticated attacker can access the affected system using the hard-coded credentials and read files on the target system.



4) Reversible One-Way Hash (CVE-ID: CVE-2019-13539)

CWE-ID: -

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


The vulnerability allows a local user to bypass authentication on the target system.

The vulnerability exists due to the the affected products use the decrypt algorithm for OS password hashing. While interactive, network-based logins are disable and local user can use other vulnerabilities to obtain local shell access and access these hashes.
