Workarounds and Mitigations

Please follow the steps below to implement the workaround:
1. Stop the Portal Server.
2. Find convertors.xml
for Portal version 6.1 check:
<portal_server>/shared/app or <portal_server>lwo/preq.odc/shared/app
for Portal version 7 and 8 check:
<portal_server_root>/wp_profile/PortalServer/dcs
3. Backup this file to restore it after the fix has been applied.
4. Remove all <input> and <output> entries inside all <convertor> tags in the
convertors.xml file as shown in the following example.
Find all sections like this:
<convertor>
<input>application/vnd.openxmlformats-officedocument.wordprocessingml.document</input>
<input>application/msword</input>
<input>application/vnd.lotus-wordpro</input>
<input>application/html</input>
<input>application/rtf</input>
...
<output>application/vnd.ibm-odcrte.zip</output>
...
<property name="class" value="com.ibm.wps.odc.convert.text.Stellent2RTE"/>
</convertor>
and change them like this:
<convertor>
<property name="class" value="com.ibm.wps.odc.convert.text.Stellent2RTE"/>
