ConfigServer eXploit Scanner (cxs) is a tool from us
that performs active scanning of files as they are
uploaded to the server. Initial
installation with recommended configuration options is
included with the license.
ConfigServer eXploit Scanner
Active scanning can be performed on all text files
- Actively scans all modified files within user accounts using the cxs Watch daemon regardless of how they were uploaded
- PHP upload scripts (via a ModSecurity hook)
- Perl upload scripts (via a ModSecurity hook)
- CGI upload scripts (via a ModSecurity hook)
- Any other web script type that utilises the HTML form ENCTYPE multipart/form-data (via a ModSecurity hook)
The active scanning of files can help prevent
exploitation of an account by malware by deleting or moving
suspicious files to quarantine before they become active.
It can also prevent the uploading of PHP
and perl shell scripts, commonly used to launch more
malicious attacks and for sending spam.
cxs also allows you to perform on-demand scanning
of files, directories and user accounts for suspected
exploits, viruses and suspicious resources (files,
directories, symlinks, sockets).
You can run scans of existing user data
to see if exploits have been uploaded in the past or via
methods not covered by the active scanning. It has been
tuned for performance and scalability.
Exploit detection includes
- Over 4000 known current exploit script fingerprint matches (in addition to standard ClamAV detection)
- Known viruses via ClamAV
- Regular expression pattern matching to help identify known/unknown exploits
- Filename matching
- Suspicious file names
- Suspicious file types
- Binary executables
- Some illegal web software installations
- Custom user specified regular expression patterns
- Comprehensive constant scanning of all user data using the cxs Watch daemon - scans all
user files as soon as they are modified
- Daily check for new Exploit Fingerprints
- Check for old version of popular web scripts (e.g. Wordpress, Joomla, osCommerce)
- Bayes probability scanning - scans scripts and passes the contents through an algorithm which produces a probability as to whether it is an exploit
- Monitor files and directories for changes and send an email report of activity
- IP Reputation System. The system provides a variety of IP blocklists gathered from information that is submitted by participating servers. This dual aspect provides the information to help protect the server using the reputation from active attacks
- Major update to Script Version Scanning. cxs now scans for more than 200 individual applications, more than 200 WordPress plugins and more than 200 Joomla Extensions. Over 700 in total!
