NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the /rrdp endpoint. Prior to 0.12.1 a direct query for any existing directory under /rrdp/, rather than an RRDP file such as /rrdp/notification.xml as would be expected, causes Krill to crash. If the built-in /rrdp endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated.
Weakness
An exception is thrown from a function, but it is not caught.
