Overview A Server-Side Template Injection vulnerability was discovered in in Dispatch Message Templates. Impact Authenticated users can achieve Remote Code Execution (RCE) via Server-Side Template Injection (SSTI) using Dispatch's notification functionality if their instance contains an enabled message template containing malicious code. Admin users have full access to create, edit, and delete these message templates. Non-admins can also exploit this vulnerability if they are the first to create a message template as they do not have the permissions to edit an existing message template. All versions of Dispatch before the pull request: https://github.com/Netflix/dispatch/pull/5002, are impacted and should be patched immediately. Description Dispatch's notification service uses Jinja templates to generate messages to users. Jinja permits code execution within blocks, which were neither properly sanitized nor sandboxed. This vulnerability enables users to construct command line scripts in their custom message templates, which are then executed whenever these notifications are rendered and sent out. Workarounds and Fixes This issue was fixed in the PR, https://github.com/Netflix/dispatch/pull/5002. Ensure to upgrade your Dispatch instances to the new version. It can be done as follows: git clone https://github.com/Netflix/dispatch.git References https://github.com/Netflix/dispatch https://github.com/Netflix/security-bulletins/blob/master/advisories/nflx-2024-003.md
