When using multiple browser tabs, policies can become corrupted

Technical Articles ID: KB90280
Last Modified: 12/9/2021

Environment

Endpoint Security (ENS) 10.x
ENS for Linux 10.x
ENS for Mac 10.x
ePolicy Orchestrator (ePO) 5.x
VirusScan Enterprise (VSE) 8.x

Problem

Policy corruption can occur when you use multiple tabs in a single browser session to access ENS or VSE policies in the ePO console.

The following is an example of how the issue can occur:

Open the Access Protection policy in tab 1.
Open the Exploit Prevention policy in tab 2.
Modify the Exploit Prevention policy and save.
The Access Protection policy becomes corrupted.
The Exploit Prevention policy fails to save correctly.

Cause

ePO stores the policy object and policy settings object IDs in the user session. When policies are open in multiple browser tabs, the session data is overwritten. This action leads to the corruption on the save.

Solution

This issue is resolved in ENS 10.6.1 April 2020 Update and ENS 10.7.0 February 2020 Update.

Our product software, upgrades, maintenance releases, and documentation are available on the Product Downloads site.

NOTE: You need a valid Grant Number for access. See KB56057 - How to download Enterprise product updates and documentation for more information about the Product Downloads site, and alternate locations for some products.

Workaround

To prevent this issue from occurring, use only a single tab.
