| Description |
|---|
| Some clients try to guess the character encoding of text media when the mandated default of ISO-8859-1 should be used. Some browsers will interpret as UTF-7 when the characters are safe for ISO-8859-1. This can create the potential for a XSS attack. To defend against this, enforce_encoding_in_get_writer must be set to true. |
| ℹ️ Check |
|---|
| At the command line, run the following command: # grep ENFORCE_ENCODING_IN_GET_WRITER /usr/lib/vmware-sso/vmware-sts/conf/catalina.properties Example result: org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER=true If "org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER" is not set to "true", this is a finding. If the "org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER" setting does not exist, this is not a finding. |
| ✔️ Fix |
|---|
| Navigate to and open: /usr/lib/vmware-sso/vmware-sts/conf/catalina.properties Update or remove the following line: org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER=true Restart the service with the following command: # vmon-cli --restart sts |
