Security Updates
All security-relevant changes from the latest BCS releases
The regular installation of updates is one of the most important security measures that users should pay attention to. We are constantly working to identify potential security vulnerabilities and fix them immediately. Updates to our software therefore always include bug fixes and eliminated security risks. Therefore, update your BCS installation regularly in order to be protected against potential risks in the best possible way.
Secure with the latest BCS version
It's worth updating to the latest BCS version! The latest BCS version always contains the fixes to security gaps made in previous releases.
We evaluate the vulnerability of the fixed vulnerabilities according to the Common Vulnerability Scoring System (CVSS). This is a method that provides a qualitative rating of severity. CVSS is not a measure of risk. CVSS consists of three metric groups: Base, Temporal and Environmental. The base metrics result in a score between 0 and 10, which can then be modified by scoring the temporal and environmental metrics.
The color coding of the severity level is based on the ratings given in the CVSS v3.0 specification:
Severity | Color coding | Severity Score Range |
|---|---|---|
| None | CVSS-Score | 0.0 |
| Low | CVSS-Score | 0.1 - 3.9 |
| Medium | CVSS-Score | 4.0 - 6.9 |
| High | CVSS-Score | 7.0 - 8.9 |
| Critical | CVSS-Score | 9.0 - 10.0 |

| Der Apache Tomcat, which is supplied as standard with the installation via the Projektron BCS Installer, has been updated to version 9.0.90. This closes a security gap. We recommend that you also update the Apache Tomcat in your installation to the version specified in the installation requirements. As Tomcat should only be used for Projektron BCS, unnecessary parts of the installation should be removed when updating Apache Tomcat. Please remove files and directories in the /tomcat/webapps/ directory to avoid problems in connection with Tomcat sample files. Further information on the update can be found on the Projektron support server in FAQ entry 449. | CVSS-Score 7.5 | 23.2 |

| This entry is only relevant if you use the project e-mail import with subversion integration.When importing emails with SVN integration enabled, it was potentially possible to import commit objects that did not correspond to actual SVN commits. The prerequisite for this is that an attacker is able to send any emails to the email import account. To prevent this, a secret is now required for SVN integration. Further information on this can be found in the administration documentation in the chapter "Subversion Integration". | CVSS-Score 3.9 | - |

| If a user received the permissions to a ticket exclusively via a query, it was possible to continue receiving email notifications for this ticket even after the query had been answered. This has been fixed. In the course of this, the behaviour of the field "More email addresses" on tickets was changed. Previously, BCS searched for a person belonging to this email address and, if a person was found, the email was sent to the main address of this person. This is no longer the case, the email address entered in the field is always used. | CVSS-Score 3.1 | 22.2 |
