Server side template injection In gogs.io/gogs
Description
Gogs allows argument injection during the previewing of changes
Impact
Unprivileged user accounts can write to arbitrary files on the filesystem. We could demonstrate its exploitation to force a re-installation of the instance, granting administrator rights. It allows accessing and altering any user's code hosted on the same instance.
Patches
Unintended Git options has been ignored for diff preview (https://github.com/gogs/gogs/pull/7871). Users should upgrade to 0.13.1 or the latest 0.14.0+dev.
Workarounds
No viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions.
