Detailsinfo

A vulnerability, which was classified as problematic, has been found in GoCD up to 24.4.0. This issue affects an unknown part. The manipulation with an unknown input leads to a xml external entity reference vulnerability. Using CWE to declare the problem leads to CWE-611. The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

GoCD is a continuous deliver server. GoCD versions 16.7.0 through 24.4.0 (inclusive) can allow GoCD admins to abuse a hidden/unused configuration repository (pipelines as code) feature to allow XML External Entity (XXE) injection on the GoCD Server which will be executed when GoCD periodically scans configuration repositories for pipeline updates, or is triggered by an administrator or config repo admin. In practice the impact of this vulnerability is limited, in most cases without combining with another vulnerability, as only GoCD (super) admins have the ability to abuse this vulnerability. Typically a malicious GoCD admin can cause much larger damage than that they can do with XXE injection. The issue is fixed in GoCD 24.5.0. As a workaround, prevent external access from the GoCD server to arbitrary locations using some kind of environment egress control.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-56322 since 12/19/2024. The exploitation is known to be difficult. The attack may be initiated remotely. Additional levels of successful authentication are necessary for exploitation. Neither technical details nor an exploit are publicly available.

Upgrading to version 24.5.0 eliminates this vulnerability.
