CSCvt31436 | CCE - Tomcat upgrade to resolve CVE-2020-1938 breaks cceadmin and websetup |
An upgrade to Apache Tomcat on Unified Contact Center Enterprise (Unified CCE) components breaks the cceadmin and websetup page. This error message is given:
HTTP Error 500.0 - Internal Server Error Calling LoadLibraryEx on ISAPI filter "C:\icm\tomcat\bin\i386\isapi_redirect.dll" failed
This is a mandatory upgrade to address the vulnerability described in CVE-2020-1938. It might not be an option to revert back to an older Tomcat version.
Tomcat version 7.0.100 or greater.
This error is given:
HTTP Error 500.0 - Internal Server Error Calling LoadLibraryEx on ISAPI filter "C:\icm\tomcat\bin\i386\isapi_redirect.dll" failed
The cceadmin and websetup page does not load after an upgrade to Tomcat 7.0.99 and later on Unified CCE 11.6.
Workaround 1. Provide Permissions
The permissions message states:
C:\icm\tomcat folder does not have enough permissions.
In order to provide enough permissions in the Tomcat directory and subdirectories, complete these steps:
<install_drive>:\icm\tomcat\conf\server.xml
<install_drive>:\icm\ssl\cfg\server-iis.xml
<install_drive>:\icm\bin\server.xml.IIS.custom
In each file, replace this line:
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" address="127.0.0.1" maxPostSize="5242880" />
with this line:
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" address="127.0.0.1" maxPostSize="5242880" secretRequired="false" allowedRequestAttributesPattern=".*" />
