csf

Bug fix:

• Fixed syntax issue with the csf.deny application feature added in v2.15 that prevents csf adding the IP to csf.deny

Some new features and bugfixes:

• Added a list of the applications that lfd blocks a login failure for into csf.deny, e.g. (ftpd,mod_security)
• Extended LF_DIRWATCH with a new option LF_DIRWATCH_FILE. This feature will watch for changes in directories and files listed in csf.dirwatch using an md5sum for the ls output. If the md5sum changes between checks an email alert is sent using watchalert.txt
• Modified pid file locking for the lfd process to ensure duplicate processes won’t run
• Completely reworked the child reaper code to prevent SIG_CHLD kernel errors. Removed DISABLE_SIG_CHLD_IGNORE from csf.conf for new installs
• Added new option to csf.fignore that allows you to ignore files owned by a specific user by adding an entry in the format user:bob
• Fixed bug in LF_DSHIELD timer code
• Wrapped LF_DSHIELD and LF_SPAMHAUS in a 10 second timeout to fetch their respective data
• New Feature – GLOBAL_ALLOW and GLOBAL_DENY options allow you to specify a URL where csf can grab a centralised copy of an IP allow and/or deny block list of your own. They are both retrieved after a LF_GLOBAL interval in seconds by lfd
• Added WHM UI changes for LF_DIRWATCH_FILE

Some additions:

• Added cPanel version check to Security Check
• Added suspicious symlink checking to LF_DIRWATCH
• Added a Display All Comments to Security Check
• Added hyperlinks to WHM URLs in Security Check comments
• Fixed the Apache Limits comments of the Security Check
• Added shell limit checks to Security Check
• Added Background Process Killer to Security Check

Changes:

• Typo corrections in output text
• Removed dependencies on external modules for the Server Check report

New feature:

• Changed app name to ConfigServer Security & Firewall
• New Feature – Added Server Security Check report to WHM UI

Changes:

• Fixed log file error if DShield or Spamhaus block list retrieval fails
• Added perl regex matching in csf.fignore (see updated readme.txt)

This should stabalise the LF_DIRWATCH feature now:

• Fixed a looping issue with the temporary Connection Tracking block code
• Added a 10 second timeout for the LF_DIRWATCH child to prevent looping

Some bugfixes and changes to LF_DIRWATCH:

• In LF_DIRWATCH, allow wildcard matching at the end of a file name in csf.fignore, such that /tmp/clamav* will ignore any files starting with /tmp/clamav, e.g. /tmp/clamav-1234
• Added a throttle to LF_DIRWATCH – if more than 10 emails are being emailed in one pass, LF_DIRWATCH will create the file /etc/csf/csf.dwdisable and then disable itself. To get it watching again, either restart lfd or delete that file
• Fixed a bug where LF_DIRWATCH always reported the same file when different files had been detected in a pass

Brand new feature:

• New feature: Directory Watching. LF_DIRWATCH enables lfd to check /tmp and /dev/shm and other pertinent directories for suspicious files, i.e. script exploits. These can optionally be moved into a tarball
• Directory Watching false-positives can be listed in csf.fignore which is accessible from the WHM UI

New version with a nice new feature for those with multiple NICs:

• Modified code to allow for multiple ethernet NICs so that all rules are applied to all NICs, for example, if you have IP’s spread over eth0 and eth1. To do this you have to set ETH_DEVICE = “eth+”
