Known Issues in Splunk UBA

This version of Splunk UBA has the following known issues and workarounds.

If no issues are listed, there are no known issues at this time.


Date filed Issue number Description
2022-09-06 UBA-16289 7-node UBA deployment has an invalid value for system.messaging.rawdatatopic.retention.time in caspidatunables-7_node.conf

Workaround:
SSH into the management node as the caspida user

1. Edit the following two files: 

/etc/caspida/local/conf/deployment/uba-tuning.properties
/opt/caspida/conf/deployment/recipes/caspida/caspidatunables-7_node.conf
Correct field 
system.messaging.rawdatatopic.retention.time
to be 
1d
instead of 
1dq

2. Sync-cluster 

/opt/caspida/bin/Caspida sync-cluster /etc/caspida/local/conf/deployment/
/opt/caspida/bin/Caspida sync-cluster /opt/caspida/conf/deployment/recipes/caspida/

3.Restart cluster 

/opt/caspida/bin/Caspida stop-all
/opt/caspida/bin/Caspida start-all
2022-04-14 UBA-15607, UBA-14237 Unable to create Anomaly Table filter or AAR specifying filter for Specific Devices when specifying over 20 CIDR/s
2022-01-25 UBA-15321 Upgrade script for ubuntu systems need revised commands to install external packages correctly

Workaround:
If the upgrade to UBA 5.0.5 failed in a lockdown environment with no internet connection, perform the following steps on the failed UBA node:
  1. Edit the file: /home/caspida/patch_uba_505/bin/utils/patch_uba.sh
  2. Replace the line ssh ${host} "${SUDOCMD} apt-get -y -f install ${ExtPkgsDir}/openjdk*.deb && exit" with ssh ${host} "${SUDOCMD} dpkg --force-confold --force-all --refuse-downgrade -i ${ExtPkgsDir}/openjdk*.deb && exit"
  3. Replace the line ${SUDOCMD} apt-get -y -f install ${ExtPkgsDir}/ca-certificates*.deb with ${SUDOCMD} dpkg --force-confnew --refuse-downgrade -i ${ExtPkgsDir}/ca-certificates*.deb
  4. Save the file.
  5. Run the upgrade script again.

2021-12-06 UBA-15164 Download Diagnostics "Parsers" for multi-node misses /var/log/caspida/jobexecutor*
2021-09-29 UBA-14894 UBA EPS drops after Splunk 8.2.1/8.2.2 upgrade on search heads used by data sources
2021-05-04 UBA-14516 Health Monitor - An error occurred while retrieving data - Error from /uba/monitor Invalid Json response: Error in getting the response Parameters: {"queryStatus":true,"queryDataQualityStatus":true}

Workaround:
  1. Stop all Splunk UBA services on node 1: 
    /opt/caspida/bin/Caspida stop-all
  2. On each Splunk UBA node, edit the java.security file in - 
    /usr/lib/jvm/java-*/jre/lib/security/java.security
    and remove TLSv1 and TLSv1.1 from the following property 
     jdk.tls.disabledAlgorithms
  3. The folder in /usr/lib/jvm will be different on different environments. For example- The absolute path for java.security file in Ubuntu is, 
    /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security
  4. Start all Splunk UBA services on node 1: 
    /opt/caspida/bin/Caspida start-all
  5. Verify there are no more errors in UI.

2021-04-13 UBA-14493 IP change steps not working
2021-01-25 UBA-14390 New threats sent to ES have incorrect "status" field value
2021-01-11 UBA-14379 Discrepancy between Threats and notable events in ES

Workaround:
As a temporary workaround, edit the search in ES. Look for the "UEBA Threat Detected" correlation search removing '| search uba_threat_status != closed'



2020-10-30 UBA-14287, UBA-17142 Issue while deleting datasource referencing other UBA original primary cluster
2020-06-27 UBA-14198 Anomaly actions rules with wildcards can cause syntax error and failure

Workaround:
Contact support to fix your sql query
2020-06-25 UBA-14197 SplunkDirect Cloud model errors with unsupported object_type fields

Workaround:
This issue is observed while ingesting SplunkDirect Cloud category data. Only the following values for the "object_type" field are supported: 
Collaboration, Cookie, File, FileSystem, Folder, Registry, SecretObject, ServiceObject, SamDomain, Computer, Share, SharePoint, Token, USB, User, Unknown

If there are any other values in your environment for "object_type" field, modify the SPL to evaluate unsupported values to "Unknown". For example: 

| eval object_type=case(object_type == "File", "File", object_type == "Folder", "Folder", object_type == "Web", "Unknown")
2020-06-23 UBA-14195 Reduce disk consumption of scanning model by filtering non-relevant data
2020-06-05 UBA-14140 HA/DR failover fails if Primary is down during failover
2020-06-02 UBA-14097 First attempt to create new AAR rules fails after standby failover
2020-05-11 UBA-13948 HA/DR After failover, the scheduled datasources (hrdata and assets) are not running on schedule

Workaround:
On node1 of promoted system, run 
curl -X PUT -Ssk -v -H "Authorization: Bearer $(grep '^\s*jobmanager.restServer.auth.user.token=' /opt/caspida/conf/uba-default.properties | cut -d'=' -f2)" https://localhost:9002/datasources/moveDS?name=<Name of Datasouce>

Where <Name of Datasouce> is the data source name displayed on UI

2020-05-11 UBA-13950 HA/DR after failover system does not restart until setup-containerization is run on standby system

Workaround:
After failover, run 
/opt/caspida/bin/Caspida stop
/opt/caspida/bin/Caspida setup-containerization
/opt/caspida/bin/Caspida start
2020-05-11 UBA-13947 HA/DR switching roles of Primary/Secondary can fail
2020-05-11 UBA-13942 HA/DR Standby failover failed when Postgres on Primary is down

Workaround:
On node hosting Postgres, run 
psql -d caspidadb -c 'ALTER SUBSCRIPTION subscription_caspida DISABLE'
psql -d caspidadb -c 'ALTER SUBSCRIPTION subscription_caspida SET (slot_name = NONE)'
psql -d caspidadb -c 'DROP SUBSCRIPTION IF EXISTS subscription_caspida'

On master node, run failover again 

touch /opt/caspida/conf/replication/properties/standby
/opt/caspida/bin/replication/failover

2020-05-01 UBA-13896 HA/DR CaspidaCleanup breaks for system in standby mode

Workaround:
Run the following commands on the Splunk UBA node hosting Postgres before cleanup: 
psql -d caspidadb -c 'BEGIN; SET transaction read write; ALTER DATABASE caspidadb SET default_transaction_read_only = off; COMMIT
psql -d caspidadb -c 'DROP PUBLICATION IF EXISTS publication_caspida'
psql -d caspidadb -c 'DROP SUBSCRIPTION IF EXISTS subscription_caspida'
2020-04-27 UBA-13856 Upgrade failed in Redhat/CentOS/OrclLinux without internet access or local proxy which does not include JVM updates.

Workaround:
Upgrading to Splunk UBA 5.0.3 on Linux systems requires downloading an installer package with the release number 5.0.3.1. See How to install or upgrade to this release of Splunk UBA at https://docs.splunk.com/Documentation/UBA/5.0.3/Install/InstallUpgradePath for instructions.
2020-04-22 UBA-13845 Backup/Restore and Replication logs not included in "Download Diagnostics"
2020-04-19 UBA-13824 HA/DR HDFS data transfer fails with ssh timeout

Workaround:
Edit /opt/caspida/conf/replication/ssh_config file on master node on both primary and standby clusters so it looks like this: 
Host *
    ControlMaster no
    ControlPath /var/vcap/sys/tmp/caspida/%r@%h-%p
    ControlPersist 3600
    StrictHostKeyChecking no
    ServerAliveInterval 30
    ServerAliveCountMax 10

Sync on both primary and standby cluster: 

/opt/caspida/bin/Caspida sync-cluster /opt/caspida/conf/replication

Then rerun setup with reset option on primary and standby systems, and kick off the first sync cycle.

2020-04-10 UBA-13810 CSV Export of 3000 or More Anomalies Fails
2020-04-07 UBA-13804 Kubernetes certificates expire after one year

Workaround:
Run the following commands on the Splunk UBA master node: 
/opt/caspida/bin/Caspida remove-containerization
/opt/caspida/bin/Caspida setup-containerization
/opt/caspida/bin/Caspida stop-all
/opt/caspida/bin/Caspida start-all
2020-01-17 UBA-13546, UBA-13166 Custom model configuration is not getting replicated on the standby

Workaround:

Run the following commands on node 1 in the standby cluster to copy files from the primary cluster to the standby cluster, then restart job manager. Be sure to replace <p_node1> in the example with the actual name or IP address of node 1 in your cluster. 

rsync -av <p_node1>:/etc/caspida/local/conf/[am]* /etc/caspida/local/conf
sudo service caspida-jobmanager restart
2019-10-07 UBA-13227 Backend anomaly and custom model names are displayed in Splunk UBA

Workaround:
Click the reload button in the web browser to force reload the UI page.
2019-08-06 UBA-12910 Splunk Direct - Cloud Storage does not expose src_ip field

Workaround:
When ingesting Office 365 Sharepoint/OneDrive logs through Splunk Direct - Cloud Storage, add an additional field mapping for src_ip in the final SPL to be mapped from ClientIP (| eval src_ip=ClientIP). Make sure to add src_ip in the final list of fields selected using the fields command. For example: 
| fields app,change_type,dest_user,file_hash,file_size,object,object_path,object_type,parent_category,parent_hash,sourcetype,src_user,tag,src_ip
