Just need some advice about rokcommon.
I have one of my sites hacked through public_html/libraries/rokcommon/Overrides for spam.
Can I remove rokcommon or how should i proceed?
Regards
Mike

Hi Mike,
Rokcommon is used a lot in the templates so it cannot be removed. We take security very seriously indeed and so far we are unaware of any vulnerability, but that doesn't mean someone couldn't have found something.
Also it is important to bear in mind that once a server is breached any file can be changed. We would need to see the apache logs showing which file was used to compromise the site. Obviously if there is an issue we would want to fix it ASAP. You can attach any details or information via the 'Secure' tab at the top of the post reply box.
In the meantime please install the latest RokSprocket to get back to your original files.
Many thanks.
Please search forums before posting. Please make sure your post includes the version of the CMS you are using and a link to the problem. Annotations on screenshots can also be helpful to explain problems/goals. Please use the "secure" tab for confidential information

Howdy
Just so you know libraries/rokcommon/Overrides only contains php class files and has no executable stand alone php scripts? It is very very unlikly the source of your compromise.
Can you please give us more info about what you are seeing?

- As well just to clear things up. RokCommon is used by RokGallery and RokSprocket. If you need to remove it remove all RokSprocket and RokGallery components, modules, and plugins, then remove the RokCommon library and plugin. This is all doable via the normal joomla extension manager. It is nest to do the removal in that order in order to keep your site from having an issue.

As David said, it is very likly that you have a lot more files compromised and modified. Once someone is able to get into your site they modify lots of different files in order to give them as much exposure and chances of always having a hacked site accessable again.
If they spam is coming from libraries/rokcommon/Overrides it mean that they most likly modifed those files in order to do sending of spam. This is probably not ther point where they compormised your site.

So what would be the best way to tackle this? Any suggestions as my server has been compromised and they are all rocket themes on it.
The last one came from mod_main menu which I was not using so i deleted it. This has been my best defense so far. But with rokcommon I could not remove it as I thought it was connected to other components or plugins etc. - Last Edit: 10 years 8 months ago by Mike Blayden.

No that's not part of RokCommon. You should remove it immediately. It is not spam, it's mostly likely a control script that hackers can use to completly take over and manipulate your site, and possibly your server. They have hacked your site and just placed that file in that rokcommon folder. They might also have placed this file or similar ones, in any number of folders in case you find one, they have plenty more to fall back on. You should search your entire file system for files like this one, and remove them.
I strongly advise you search the VEL for any extensions that you are using, there might be a known vulnerability in one of your extensions you are using:
vel.joomla.org/live-vel.html
You should ensure your running the latest version of all your extensions (including RocketTheme ones, even though we have no outstanding known vulnerabilities).
Also, there are quite a few vulnerabilities that are always being fixed in the Joomla CMS itself. If you are not running the latest version, I suggest you update that too.
FYI, this week there was a particularly serious vulnerability found in JomSocial. If your running that I suggest you get the latest security fix ASAP, it's a nasty one.
