JIRA Client user agent filter

Sandro Juković

Hi,

We wanted to block user agent Jakarta Commons-HttpClient/3.0 (JIRA Client/2.3.5.5825.285) from downloading data from our JIRA.

Atlassian told us to do that on a network/server level.

My System admin has configured .htaccess file and now nothing happens (JIRA client still downloads info from JIRA). He told me that JIRA Apache server is somewhat different and that he isn't sure if he put a file in the right directory.

Directories where the file is are:
1. C:\Atlassian\JIRA 4.1.2\atlassian-jira
2. C:\Atlassian\JIRA 4.1.2\bin

.htaccess file contains this text:
"BrowserMatchNoCase Jakarta bad_bot
Order Deny,Allow
Deny from env=bad_bot"

He is not an expert for Apache servers, but MS expert so we need help on this issue.

Thanks,

Hi Sandrox, may I ask you why would you block JIRA Client? It's not a bot, it's a user agent - a desktop application for working with JIRA - see details here. If you think your JIRA Server is stressed because of JIRA Client, it's often an indication that the server is at its maximum capacity and needs upgrade. But JIRA Client users can also be advised to lower the update rate to minimize the effect on the server.

Anyway, if you would still like to block it by User Agent, the important question is whether all your requests to JIRA are served through Apache. Your configuration looks valid, but it applies only to requests coming through Apache. Also, check that AllowOverride for the directory includes FileInfo and Limit.

Hi Igor,

Thanks for your answer and help,

first of all, I have downloaded JIRA Client trial to test its features, it works fine. But the problem is that we have some Custom fields which we are hiding from certain external users.

In browsers like Chrome, Mozilla, IE etc., this hiding works fine. It also works for apps on mobile phones. Only JIRA Client can see this hidden fields. Even when we turn off remote API (I have also turned off RPC service and REST service). So, when some user adds hidden fields to his view in JIRA client he can see them.

Therefore, this is a security risk for us and that is the reason we want to turn off access to JIRA Client's user agent.

"Also, check that AllowOverride for the directory includes FileInfo and Limit." --> how to set this up?

Cheers,

Thanks for the explanation! I see.

From security standpoint, JIRA Client does not exploit any unknown holes and does not do any magic. You can block JIRA Client but the security vulnerability of your configuration will still remain. If JIRA Client can easily get that data from your system, so can any other hand-crafted code.

I would check the XML view of the issues, which is mainly used to load issue data. Open any issue and select XML view, then see if the sensitive fields are there. Note that if XML view is disabled from your menus, it doesn't mean that it won't work if requested directly via URL.

On Apache: AllowOverride is typically set in the site configuration file, like /etc/apache2/sites-enabled/whatever-site-name-is, inside <Directory> setting. You can change it to AllowOverride All.

Hope this helps
Igor
