VULNERABILITY CLASSIFICATION

The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss). The CVSS environmental score is specific to the customer’s environment and will impact the overall CVSS score. The environmental score should therefore be individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a community-developed list of common software security weaknesses. This serves as a common language and as a baseline for weakness identification, mitigation, and prevention efforts. A detailed list of CWE classes can be found at: https://cwe.mitre.org/.

Vulnerability CVE-2020-10052

The affected application writes sensitive data, such as usernames and passwords in log files. A local attacker with access to the log files could use this information to launch further attacks.

CVSS v3.1 Base Score	5.5
CVSS Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C
CWE:	CWE-532: Insertion of Sensitive Information into Log File

Vulnerability CVE-2020-10053

The affected application writes sensitive data, such as database credentials in configuration files. A local attacker with access to the configuration files could use this information to launch further attacks.

CVSS v3.1 Base Score	5.5
CVSS Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C
CWE:	CWE-312: Cleartext Storage of Sensitive Information

Vulnerability CVE-2020-10054

The affected application does not properly handle the import of large configuration files. A local attacker could import a specially crafted file which could lead to a denial-of-service condition of the application service.

CVSS v3.1 Base Score	5.5
CVSS Vector	CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C
