SPIP Security Alert + new version SPIP 2.0.9

(from an alert posted on “spip-ann” mailing list)

Hello,

A big security issue has just been discovered : this issue affects all SPIP versions from 2.0.x to 2.0.8, the branch 1.9 is also affected. This breach lets a hacker with no password at all, to take control on the SPIP website and on the web server.

This alert is to be taken seriously, as it has not been discovered by someone “nice” but by a real “naughty one” who took control on an existing website in order to insert malwares on it.

Security Screen :

If you have no way to upgrade completely at once, we suggest you to fix the breach as soon as possible by installing on your SPIP website the “security screen”. You can discover this at :

This “screen” lets you block certain attacks without the need of upgrading SPIP.
