Description

This security bulletin contains information about 2 vulnerabilities.


1) Cleartext transmission of sensitive information (CVE-ID: CVE-2017-9637)

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/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 attacker to obtain credentials on the target system.

The weakness exists due to cleartext transmission of sensitive information. When connectivity to third party databases is configured to use a SQL user name and password, a local attacker sniff details from the connection string.

Successful exploitation may result in compromise of credentials used to connect to third party databases.


2) Inadequate encryption strength (CVE-ID: CVE-2017-9635)

CWE-ID: CWE-326 - Inadequate Encryption Strength

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


The vulnerability allows a local attacker to obtain credentials on the target system.

The weakness exists due to weakness in the password hashing algorithm. When Ampla MES users are configured to use Simple Security, a local attacker can reverse the user’s password.

Successful exploitation may result in compromise credentials of Ampla users configured with Simple Security.
