**Name of the Vulnerable Software and Affected Versions** NLnet Labs Krill versions prior to 0.12.1 **Description** The issue arises when a direct query is made for any existing directory under the "/rrdp/" endpoint, rather than an RRDP file, causing the server to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, malicious remote parties can exploit this to crash the publication server, affecting its availability but not the repository content itself. **Recommendations** For versions prior to 0.12.1, update to version 0.12.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/rrdp" endpoint to prevent malicious queries from causing the server to crash.
