ThingWorx 9.1.8 uses log4j 2.17 and is not exposed to the current CVEs with older log4j versions. Guidance for older ThingWorx versions should be referenced here.

Fixed potential security issues, including items proactively identified by vulnerability scanning software or PTC Quality Assurance testing. Please upgrade as soon as possible to take advantage of these important improvements.

PTC has recently implemented a new support policy with respect to Identity and Access Management (IAM) solutions. Please see the appropriate eSupport center section for more information.

See this technical support article for important recommendations regarding the use and update of third-party software for ThingWorx.

If you are performing a maintenance upgrade (for example, 9.2.3 to 9.2.4) on MSSQL or Azure SQL, the upgrade will fail if any custom index field value length is 64 characters or more (number of columns in the index plus combined length of indexed column values - 1 = 64). Verify all custom index fields have values before starting the upgrade process. If the upgrade fails, execute the latest schema update script ( thingworx<database>SchemaUpdate<priorVersion>-to-<currentVersion>.bat/.sh) and restart Tomcat. See Maintenance Release Upgrade for more information.

If you are upgrading MSSQL, Azure SQL, or H2, the upgrade will fail if there are any missing values for the custom indexes field/column in the data table entries. Verify all custom index fields have values before starting the upgrade process. If the upgrade fails, you will need to restore the ThingWorx database and platform, remove custom indexes or provide missing values for the custom indexed fields, and then restart Tomcat. See Upgrading ThingWorx for more information.
