Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that SPIP, a website engine for publishing, would allow unauthenticated users to modify published content and write to the database, perform cross-site request forgeries, and enumerate registered users.

For Debian 8 'Jessie', these problems have been fixed in version 3.0.17-2+deb8u5.

We recommend that you upgrade your spip packages.
