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-2020-10055
Affected applications are delivered with a 3rd party component (BIRT) that contains a remote code execution vulnerability if the Advanced Reporting Engine is enabled.
The vulnerability could allow a remote unauthenticated attacker to execute arbitrary commands on the server with SYSTEM privileges.
