I am being hammered from about 30 different IPs starting a few hours ago scanning for some vulnerability I assume. So head's up if you are running Roundcude webmail.... My ossec software has been blocking after 10 attempts.

An example:


Code:
91.121.143.70 - - [08/Jan/2009:09:32:11 -0500] "GET /webmail/bin/msgimport HTTP/1.1" 404 298 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5"

Active Scans for Roundcube Vulnerabilities, Possible 0-Day

If you're running Modsecurity, you can create rules to block this activity. There are several Emerging Threat Snort rules out there (see the link...it has the ET rules linked there). Modsecurity has a perl script that converts Snort rules into Modsecurity rules.

Either that, or create a script that will parse the access_log files, looking for certain strings...make the script add the IPs generating the certain strings to a block list (host.deny or FW rule block).

I did nothing. I'm not getting hit more than 10-20 times a day so it's a negligible amount of traffic.

We've confirmed this is an active exploit for an arbitrary code exploit in RoundCube. Evidence so far points to exploited systems becoming part of a DDoS botnet. There is apparently a fix in the latest release of RoundCube.
