Overview

Java.Tomdep is a network worm copying itself between Apache Tomcat servers. When successful, it opens a backdoor connection to several Command and Control (C&C) servers. The reasons for CIRCL to address this threat in a technical report are the following:

  • High number of Apache Tomcat installations in Luxembourg
  • Simple and successful propagation process
  • Installation of a back door which allows full access to the compromised server
  • Imaginable follow-up scenarios (malware spreading to visitors, DDoS)

Background Information

The malicious software, when installed on a Tomcat server, start scanning the network for other Tomcat servers and tries to log in with a number of weak username-password combinations. If it is successful, it copies itself to the targeted server.

Other functions of the malware are:

  • Download, Upload
  • Create new processes
  • Update itself
  • Start a SOCKS proxy
  • UDP flooding

It is possible that compromised servers are used for

  • Stealing information
  • Distributed Denial of Service (DoS) attacks
  • Deliver malware to visitors

It is highly recommended to detect, block and prevent this and other attacks. In the appendix, we include also a reference of CVEs addressing vulnerabilities in Apache Tomcat. We recommend to keep Apache Tomcat updated to the latest version.

Detection

As far as we know, the malware tries to connect to the following IRC servers:

  • pic01.servepics.com:443
  • pic01.servepics.com:80
  • pic01.servepics.com:8080
  • pic01.servepics.com:13124
  • pic01.servepics.com:13122
  • 140.134.132.131
  • 8.23.224.110
  • 94.242.251.58
  • 94.242.251.57

The worm also sends collected information to the following server in HTTP on port 80/TCP. The same server apparently is used for fetching the malware:

  • update01.serveblog.net

Recommendation

If you are running an Apache Tomcat server connected to the Internet, take your time to check:

  • Review DNS logs, Tomcat logs and Firewall logs
  • Review user accounts and password strength
  • Review running processes on Apache Tomcat server

A list of domains/IP addresses is following hereafter. You might use it as a base for reviewing log files. It should be safe to block all access on your Firewalls/IPS/DNS to the following domains/IP addresses:

  • 140.134.132.131
  • update01.serveblog.net
  • 8.23.224.110
  • 94.242.251.58
  • 94.242.251.57

To avoid username-password brute forcing of the Tomcat manager interface, we recommend to apply packet filtering on the manager interface. This can be done using the Valve element from Tomcat or directly the Apache configuration using the location directive. You can also use your network or security device to restrict the source IP to required Apache Tomcat administrators.

If in doubt, don’t hesitate to contact CIRCL.

Known Vulnerabilities

  • CVE-2013-6357 2013-11-13T10:55:04.190-05:00 6.8 ** DISPUTED ** Cross-site request forgery (CSRF) vulnerability in the Manager application in Apache Tomcat 5.5.25 and earlier allows remote attackers to hijack the authentication of administrators for requests that manipulate application deployment via the POST method, as demonstrated by a /manager/html/undeploy?path= URI. NOTE: the vendor disputes the significance of this report, stating that “the Apache Tomcat Security team has not accepted any reports of CSRF attacks against the Manager application … as they require a reckless system administrator.”
  • CVE-2013-2071 2013-06-01T10:21:05.890-04:00 2.6 java/org/apache/catalina/core/AsyncContextImpl.java in Apache Tomcat 7.x before 7.0.40 does not properly handle the throwing of a RuntimeException in an AsyncListener in an application, which allows context-dependent attackers to obtain sensitive request information intended for other applications in opportunistic circumstances via an application that records the requests that it processes.
  • CVE-2013-2067 2013-06-01T10:21:05.847-04:00 6.8 java/org/apache/catalina/authenticator/FormAuthenticator.java in the form authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before 7.0.33 does not properly handle the relationships between authentication requirements and sessions, which allows remote attackers to inject a request into a session by sending this request during completion of the login form, a variant of a session fixation attack.
  • CVE-2012-5887 2012-11-17T14:55:02.813-05:00 5.0 The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 does not properly check for stale nonce values in conjunction with enforcement of proper credentials, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests.
  • CVE-2012-5886 2012-11-17T14:55:02.767-05:00 5.0 The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 caches information about the authenticated user within the session state, which makes it easier for remote attackers to bypass authentication via vectors related to the session ID.
  • CVE-2012-5885 2012-11-17T14:55:02.673-05:00 5.0 The replay-countermeasure functionality in the HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 tracks cnonce (aka client nonce) values instead of nonce (aka server nonce) and nc (aka nonce-count) values, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, a different vulnerability than CVE-2011-1184.
  • CVE-2012-5568 2012-11-30T14:55:01.893-05:00 5.0 Apache Tomcat through 7.0.x allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris.
