After upgrading 'Splunk Enterprise Security' from version 5.1.0 to 5.3.0, 'Incident Review', and Investigations page errored out with below errors.

1. Incident Review:
   URL: https://domain_name/en-US/app/SplunkEnterpriseSecuritySuite/incident_review
   Error Message: Unable to xml-parse the following data: %s

2. Investigations:
   URL: https://domain_name/en-US/app/SplunkEnterpriseSecuritySuite/ess_investigation_list
   Error Message: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Any help is welcome one. Thanks.

Try the fix for SOLNESS-18773

https://docs.splunk.com/Documentation/ES/5.3.0/RN/KnownIssues

Assuming it's ES on Windows. If that doesn't fix it, suggest contacting support (and advising the fix here too would be nice) 🙂

Cheers,

Chris.

After replacing the python script (log.py) provided by Splunk support, the issue is fixed and it works for Linux environment as well.

1. Stop Splunk.

2. Take backup of the following two files. (e.g. log.py.bak)

$SPLUNK_HOME\etc\apps\SA-Utils\lib\SolnCommon\log.py
$SPLUNK_HOME\etc\apps\SplunkEnterpriseSecuritySuite\lib\SplunkEnterpriseSecuritySuite\log.py

3. Replace the following two files with the attached modified log.py file. (Rename the file extension to ".py" before replacing.)

$SPLUNK_HOME\etc\apps\SA-Utils\lib\SolnCommon\log.py
$SPLUNK_HOME\etc\apps\SplunkEnterpriseSecuritySuite\lib\SplunkEnterpriseSecuritySuite\log.py

4. Start Splunk again.
