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-2019-13930
The web interface could allow a Cross-Site Request Forgery (CSRF) attack if an unsuspecting user is tricked into accessing a malicious link.
Successful exploitation requires user interaction by a legitimate user, who must be authenticated to the web interface. A successful attack could allow an attacker to trigger actions via the web interface that the legitimate user is allowed to perform. This could allow the attacker to read or modify contents of the web application.
At the time of advisory publication no public exploitation of this security vulnerability was known.

Vulnerability CVE-2019-13931
The web interface could allow for an an attacker to craft the input in a form that is not expected, causing the application to behave in unexpected ways for legitimate users.
Successful exploitation requires for an attacker to be authenticated to the web interface. A successful attack could cause the application to have unexpected behavior. This could allow the attacker to modify contents of the web application.
At the time of advisory publication no public exploitation of this security vulnerability was known.

Vulnerability CVE-2019-13932
The web application requests could be manipulated, causing the the application to behave in unexpected ways for legitimate users.
Successful exploitation does not require for an attacker to be authenticated. A successful attack could allow the import of scripts or generation of malicious links. This could allow the attacker to read or modify contents of the web application.
At the time of advisory publication no public exploitation of this security vulnerability was known.
