Script injection virus / Cross-Site Scripting

I had a page on a simple website for a pirate restaurant this week, and I'm looking for some advice.  The hacker managed to get an iframe tag on the homepage of the site and the content of the iframe was pretty nasty turn a few computers in stops, at least temporarily.

My hosting company, HMS, takes the position that the tag went up in the page index.html, through a possibility of script, not no matter what hole in the security of their server.  So, I try to understand where they got.

a few facts:

  • site is HTML only.  Not dynamic.
  • It is has a mail.asp on the server page, but it was not used or linked to any page. (and oddly enough, the site is on a linix server, so I think that a contribute user has slept with who at one point)
  • the site uses opentable.com, which is an online booking system which uses an iframe. (I'm asking them to assess whether or not their script could be a problem.
  • the only infected page, index.html, haven't had no call to external scripts inside - no call to any outside no files at all, not even a CSS file. It contained only internal DW javascripts like MM_swapImage html tags and a few images.
  • The site is enabled for Contribute. (I'm trying in vain to remove this, but that's another story)

If anyone can help me understand how a site like this could be compromised, I'd appreciate it.

by passing the ball, your Web site hosting provider isn't very good.  any decent host is have external firewall protection and insist that make their servers scans of minimum annual intrusion.  your html page should not cause their servers for bricks, especially if it's a virtual or shared solution.

  • ToStaticHTML MS IE String Cross - Site Scripting Vulnerability associated with the processing of alarms

    Hello

    I was wondering if someone else has noted an increase in false positives on the 2 following competitions:

    -Microsoft Internet Explorer toStaticHTML String Cross - Site Scripting Vulnerability related to treatment

    -Microsoft Office Excel Ghost Record analysis of arbitrary Code execution vulnerability

    Obvisouly I see these events because the signature has been introduced recently.

    But I wonder if these alarms I get are authentic (and I have a big problem), or if the signature must be "set" by Cisco to be a little less sensitive?

    Anyone who has experienced something similar or can enlighten?

    Thank you

    SEB.

    Hello Seb,

    As a result of this thread, we have identified a false positive in signature 30419 and corrected the signature. The signature change is currently under review and is likely to do the update of signature which releases next week.

    Please let me know if I can help with anything whatsoever in addition under this thread. If your question has been answered, please mark the thread as such so that it is useful to other users. Also, feel free to note this thread to take account of your experience.

  • Virus? Site of words...

    I just looked up a lyric of song on a lyrics site and a pop blown up on my iMac with a warning and a number of 1800 to call...

    So I immediately you quit safari and cleared the history and then ran malware bytes and no malware according to malware bytes.

    Should I do something else to search for malware or viruses?

    I'm probably being paranoid, but I appreciate any help offered.

    Thank you!

    It is probably not malicious software on the computer, but you should always look for other odd behavior or unexplained slowness.

  • Two scripts of connection in DW8

    Hello

    I suffered on one of my areas of a nasty outbreak of sql injection on a site created in DWMX2004 a few years ago. I tightened security variable form and url by updating behaviors of DW8.02 ones, but this seems to be insufficient. My next idea was to create two login accounts sql server different, one for the public pages that has only very limited privileges (can select but not insert/update / delete except if specifically required) and one for the content management system, that can do everything.

    The problem is that Dreamweaver will not allow me to have two database connections defined in a site. This means that half of my pages cannot be modified because the path to the connection file is not valid. I can have two files of connections (each one used by half of the site) and keep redefining the connection of master database because I move between files, but it's not ideal. Also, I can define two sites (one with each connection) to the same folder and keep switching between them, but it's also a pain.

    Does anyone know of a better way to do it?

    Any ideas gratefully received.

    TP

    OK, I thought about it. YOU have two active connections, but DW8 does not recognize an "old" when you added the second connection until you have closed and then reopened Dreamweaver. So it's good.

    The IP of the attacker "1.2.3.4. would be the IP of the proxy.

    By analyzing the proxy logs, I saw that a lot of different computers on my network are trying to reach the sites of Adobe to download a new version or an update, that is:

    GET http://swupmf.adobe.com/manifest/50/win/AdobeUpdater.upd HTTP/1.1

    GET http://armmf.adobe.com/arm-manifests/win/Reader9Manifest.msi HTTP/1.1

    GET http://armdl.adobe.com/pub/adobe/reader/win/9.x/9.5.0/es_ES/AdbeRdr950_es_ES.exe HTTP/1.1

    So my first question is why the attempt to reach the Adobe site match an IPS signature linked to an attempt to Cross Site Scripting.

    As I have reasearched, 41846/1A signature was published in order to attend the CVE-2012-0017: ' Cross-site scripting (XSS) vulnerability in inplview.aspx in Microsoft SharePoint Foundation 2010 gold and SP1 allows remote attackers to inject arbitrary script or HTML via JavaScript sequences in a web URL, alias 'XSS in inplview.aspx vulnerability.' "

    Then, my second question is how the Adobe site is related to CVE-2012-0017

    Thank you.

    Best regards, Dana

    Hi Dana,

    You and I must have been posted at the same time.  We noticed that a problem with this signature on one of our s sensor this morning after that S625 has been applied.  Addresses "pirate" are all internal and addresses 'target' are all over the Board, some internal and externals.  I had to disable this because it fires so often, 128 times during the last one hour.  I hope that people from Cisco can take a look at this and soon to release an update.

    Hi Himtnman,

    What web browser do you use?

    If you're unsing Internet Explorer, try the following steps to solve the problem.

    Filter Cross - Site Scripting (XSS) of Internet Explorer can prevent a Web site to add the code of script to another Web site. XSS filter watches how websites interact, and when it recognizes a potential attack, it will automatically block script code running. When this happens, you will see a message in the information bar rental, you know that the Web page has been changed to help protect your privacy and security.

    I suggest you try the steps to disable the XSS filter:

    (a) click Start and type Internet Explorer in Start Search.

    (b) press enter.

    (c) press the Alt key on the keyboard after opening Internet Explorer.

    (d) click on Tools and then click on Internet Options.

    (e) click on the Security tab.

    (f) click on custom level.

    (g) scroll to the bottom of the list.

    (h) click disable under ""Activate the filter XSS. " "

    (i) click on ok to close the Properties window.

    (j) restart Internet Explorer and check to see if the problem is resolved.

    Hope this information helps. If you need additional help or information on Windows, I'll be happy to help you. We, at tender Microsoft to excellence.

  • Integrating Wordpress in need of Muse dynamic height with cross domain content-based

    Given that Muse does currently not support articles and Wordpress integration I decided to use an iFrame.

    My goal is to have the height of the iframe dynamic change based on the content of my Wordpress blog. I understand that this is a common problem with frames that are hosted on different domains.

    I'm running by having more to compensate with a bunch of deadspace to leave enough room. You can also get the horrible scrolling to the search bar.

    I tried using cross-site scripting, JQuery, and postMessage but can't find out how to put the right code in Muse and Wordpress for them to communicate in either sense.

    Please, any help on this would be greatly appreciated.

    Apparently, you try to insert the iframe to another area and because of the "Same origin" security policy, you are not authorized to access the document property of the iframe object. This will not happen if the inserted iframe is on the same domain.

  • fill with links on websites that have nothing to do with this Web site

    Words are underlined and provide links to Web sites that have nothing to do with the site I'm. So I get a pop up video advertising that started the same time these links that presented themselves. How can I stop this?

    You can have an unwanted extension that injects these ads sites. Try this:

    Disable all non-essential or unrecognized extensions on page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then, when in doubt, turn off.

    Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Which empty ads?

    Note: If no delete button for an extension, you can usually uninstall via Control Panel, uninstall a program. I suggest clicking on the column heading "installed during the" group by date to see if all the grouped items dragged to your computer during a recent free software install.
