Severity: 2-Critical


TMM may crash or return no result found when there is one when using contains external data group.


TMM crashes or result not found when there should be a result.


External data group sets first to "starts-with" and then switch to "contains" may crash the TMM. If on the other hand, TMM is started with search "contains" from the start, no results may be found by policy even though there might be a result. The is because, the external policy is not populated at all or entirely before the search happens. The starts-with works as it is populating on demand and is the reason and will partially populate it as needed, but when a switch to "contains" happens, it expects it to be entirely populated.


A workaround is possible if starts-with could be used instead of "contains".

Fix Information

Search with "contains" will make sure the policy with external data group is entirely populated, avoiding the crash and making a search result successful if there is a match.
