Do Service Desk Manager/Service Catalog/IT Asset Manager get impacted by Ghostcat vulnerability (CVE-2020-1938)


Release: 17.1 or higher
Component:  CA Service Desk Manager


Ghostcat (CVE-2020-1938)


We do not depend on AJP protocol out of the box in Service Desk Manager.  Service Catalog's might be used when its made part of out of the box cluster configuration.

ITAM itself does not directly use Tomcat as it is an IIS application.  Shared components such as AMS do rely on Tomcat but is not known to use AJP.  AMS install is located in X:\Program Files (x86)\CA\SharedComponents\AMS\

AJP connector can be disabled so that the exposure of this vulnerability does not happen.

Commenting of the AJP connector can be done like indicated in below example on any Tomcat's server.xml files.  

Below indicates that the connector is commented out.
 <!-- Define an AJP 1.3 Connector on port 8009 -->
    <!-- <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" xpoweredBy="false" allowTrace="false"></Connector> -->

If AJP Connector cannot be disabled and needs to be used (example: Catalog Cluster configuration), you can configure the “requiredSecret” attribute for the AJP Connector to set AJP protocol authentication credentials. For example (YOUR_TOMCAT_AJP_SECRET is your password)

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" address="YOUR_TOMCAT_IP_ADDRESS" requiredSecret="YOUR_TOMCAT_AJP_SECRET"

Save the file and restart appropriate product for the change to be effective

Additional Information

Out of the box, NX_ROOT/bopcfg/CATALINA_BASE  CATALINA_BASE_FS  CATALINA_BASE_REST CATALINA_BASE_SA  CATALINA_BASE_VIZ    are the main Tomcat engines that SDM offers.
