SummaryA zero-day exploit for a vulnerabilities in Apache versions less than 2.4.52 (CVE-2021-44790 & CVE-2021-44224) was publicly released on December 23rd, 2021.

Problem in Widget Preferences (hostMulti)

Hello,I'm having a problem developing my widget. When I configure my configs.xml file, I add an input like this:<preference label="List Host Name" name="list_host" defaultValue="" type="hostMulti" header="Test"/>When i fill it in like this and click on apply, host id are sent. But when I go back to widget preferences,  hosts I entered have disappeared and I get this kind of error :You should know that when I only put one host in the input, no error is displayed the input of the hosts does not work, but the input of the hostgroups (bellow) works very well.<preference label="List Hostgroup Name" name="list_hostgroup" defaultValue="" type="hostGroupMulti" header="Test"/>Do you have any idea where the problem comes from?

Does Centreon have a network config backup module?

Wondering if this product has any capability to log into Cisco devices (or others) and grab the running and startup configs for backup and auditing purposes.Even better if it also includes config change auditing and comparisons. We’d be interested in logging into and grabbing config backups for the following platforms:Cisco IOS-XR, CIsco IOS-XE, Cisco Nexus NX-OS, Palo Alto NGFW’s, Accedian devices.

How to handle multiple notification

Hello !We used centreon open source in our company and I have one difficulty with the notification.We have one central for production servers and another for everything else.Off production we have multiple environment like (development, qualification, integration and so on….)We needs to notifiy different service or people on some service depending on the environment.For example:When a queue rabbit is critical on dev notify dev teams.On qualification notify the business team of this environment etc…Today with the heritage of service template I didn’t found a valid solution.The only thing I find to manage my needs is to manage individually notification in service by host menu, service by service, but when you have hundreds edit it through the interface can take a lot of time.And I think it’s not so visual to see the notification process.The needs of sending the notification is established case by case so I cannot having a predefined list of people to notify.What is the best way to manage

Airgap Deploiement

Normally, Centreon installation need an Internet Access just after the installation to update RPM package, check the license or download Plugin Pack.Unfortunately, High secured supervision platforms can have restricted or forbidden Internet Access (even with a proxy)It will be interesting to create an Air gap procedure to install, update et maintain this kind of configuration.Right now, creating a private rpm repo is not a problem with an FTP/HTTP server, but the license check and PP download could be tricky.Is there any clue about this?
