CA20101231-01: Security Notice for CA ARCserve D2D

   Issued: December 31, 2010

   CA Technologies support is alerting customers to a security risk with
   CA ARCserve D2D. A vulnerability exists that can allow a remote
   attacker to execute arbitrary code. CA has issued an Information
   Solution to address the vulnerability.

   The vulnerability is due to default vulnerabilities inherent in the
   Tomcat and Axis2 3rd party software components. A remote attacker can
   exploit the implementation to execute arbitrary code.

   Risk Rating
   High

   Platform
   Windows

   Affected Products
   CA ARCserve D2D r15

   How to determine if the installation is affected
   Using Windows Explorer, go to the directory
   "\TOMCAT\webapps\WebServiceImpl", and look for the existence of a
   folder called "axis2-web".

   Solution

   A permanent solution will be posted soon at
   https://support.ca.com/

   In the meantime, the following workaround can be implemented to
   address the vulnerability.
    1. Stop "CA ARCserve D2D Web Service" from service control manager.
    2. Go to the directory "<D2D_HOME>\TOMCAT\webapps\WebServiceImpl",
       and remove the folder "axis2-web".
    3. Edit "<D2D_HOME>\TOMCAT\webapps\WebServiceImpl\WEB-INF\web.xml",
       and remove the content of AxisAdminServlet's servlet and servlet
       mapping.
       The content to remove will look like the text below:
       - <servlet>
       <display-name>Apache-Axis Admin Servlet Web Admin</display-name>
       <servlet-name>AxisAdminServlet</servlet-name>
       <servlet-class>org.apache.axis2.transport.http.AxisAdminServlet</s
       ervlet-class>
       <load-on-startup>100</load-on-startup>
       </servlet>
       - <servlet-mapping>
       <servlet-name>AxisAdminServlet</servlet-name>
       <url-pattern>/axis2-admin/*</url-pattern>
       </servlet-mapping>
    4. Change the username and password parameters in the axis2.xml file
       to stronger credentials that conform to your organization's
       password policies.
       "<D2D_HOME>\TOMCAT\webapps\WebServiceImpl\WEB-INF\conf\axis2.xml"
       <parameter name="userName">admin</parameter>
       <parameter name="password">axis2</parameter>
    5. Start "CA ARCserve D2D Web Service".
