ModSecurity: rule for latest Tikiwiki vulnerability

A few days ago a new vulnerability was reported in Tikiwiki 1.9.x, the software I use for the Vuurmuur Wiki. Luckily, the Community rules quickly had a rule for detecting the attack. Because I also run ModSecurity on the webserver, i wanted to have protection there as well. This rule should block the attack:

SecFilterSelective POST_PAYLOAD “jhot.php” “log,deny,status:403,msg:’LOCAL tikiwiki jhot.php attempt'”

Let’s see if I ever get a hit on it. An update for Tikiwiki as been released, so that should fix the issue completely.
