Detailsinfo

A vulnerability classified as problematic has been found in GoCD up to 24.4.0. This affects an unknown functionality of the component Backup Configuration Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

GoCD is a continuous deliver server. GoCD versions 18.9.0 through 24.4.0 (inclusive) can allow GoCD admins to abuse the backup configuration "post-backup script" feature to potentially execute arbitrary scripts on the hosting server or container as GoCD's user, rather than pre-configured scripts. In practice the impact of this vulnerability is limited, as in most configurations a user who can log into the GoCD UI as an admin also has host administration permissions for the host/container that GoCD runs on, in order to manage artifact storage and other service-level configuration options. Additionally, since a GoCD admin has ability to configure and schedule pipelines tasks on all GoCD agents available to the server, the fundamental functionality of GoCD allows co-ordinated task execution similar to that of post-backup-scripts. However in restricted environments where the host administration is separated from the role of a GoCD admin, this may be unexpected. The issue is fixed in GoCD 24.5.0. Post-backup scripts can no longer be executed from within certain sensitive locations on the GoCD server. No known workarounds are available.
