Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Cleartext transmission of sensitive information

EUVDB-ID: #VU7374

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-9637

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

Exploit availability: No

Description

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.

Mitigation

Update to version 6.5.

Vulnerable software versions

Ampla MES: 6.0 - 6.4

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Inadequate encryption strength

EUVDB-ID: #VU7375

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-9635

CWE-ID: CWE-326 - Inadequate Encryption Strength

Exploit availability: No

Description

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