Tags that use the 'Contains Pattern' operator combined with the question mark '?' value in the selection criteria do not match client name length

Technical Articles ID: KB92057
Last Modified: 10/30/2019

Environment

McAfee ePolicy Orchestrator (ePO) 5.10.x, 5.9.x

Problem

A tag is incorrectly applied, even when it is not a match for the name length.

This issue occurs when using the criteria Contains pattern comparison and the question mark (?) value.

You see the following when a tag is run manually from the Tag Catalog page via Run Tag Criteria:

It is successfully processed
The same tag criteria is not applied correctly to the client after the next agent-to-server interval (ASCI)

Cause

The manual Run Tag Criteria action treats a question mark (?) as a single character. For example, three question marks (???) match exactly three characters. The 'RuleEng' component for the ASCI handles these characters differently. When the tag 'Criteria' runs automatically via the ASCI communication, the trailing question marks (???) are ignored.

Solution

This issue is resolved in ePolicy Orchestrator 5.10.0 Update 5, which is available from the Product Downloads site.

NOTE: You need a valid Grant Number to access the update.
