While doing some testing on my site I found this code at the bottom of several of our pages. It appears to be encoding for a scaleable vector file of Pinterest's logo, that's all fine and good, but I never put it there, and I don't think anyone else did. I'm concerned that it could be some sort of exploit. I'm not sure how to decipher this? I ran it through one level of decoding but it just made it look like a different kind of code.

Anyone know if this looks harmless, or is this something bad?

    Can't you simply check who added it when in your version control history? Or is the code only on the production server and not in version control? Jul 12 '16 at 12:33
  • As @CodesInChaos suggests it may just be somone else adding code that you need to track.SVGs are unlikely to be a source for an attack though I suppose anything is possible...

  • Also, you may want to edit the post to include the decoded base64 in the question so that readers don't have to make the extra hop...

  • Tried to update, it. We are not that sophisticated, we were outsourcing our backend stuff, I mainly just do front end design and marketing, little html, css, javascript, play with Jquery a bit but that's it, our IT guy knows networks, not code... We do have some logs, but they are not permanent and a bunch have been either erased... or there are huge gaps... :T

    Casey this is not what I got running through the decoder. See @BlackMagic's answer below. Seems like a legit Pinterest SVG; what you are rightly worried about is how it got there.

What is it?

What you have are harmless SVG vectors (that are base64 encoded) being parsed using data uri in the image tag. This is a legitimate way of serving SVGs. Decoding these strings gives valid SVGs - which you can render online - https://jsfiddle.net/ykdss3b3/ (rendered as a "Save" button: https://jsfiddle.net/psL3p1hy/)

How could it be there?

This depends on your set up;

  • Multiple developers working on production
  • Plugins installed it
  • (if it's not in your source code) a browser add-on
  • ...

What to do?

If you didn't put it there, or anybody else you know that has access to your server did, remove it, and clean your production box. You may have been hacked - or it could be completely harmless and be packaged with your website theme (ie: installing a theme via wordpress).

If you have no use for a Pintrest "save" button, remove it - it's probably part of the global move that renamed "Pin it" to "Save" (https://blog.pinterest.com/en/pinterest-save-button-goes-global) and you're not making the connection - so absolutely harmless and probably added via add save button to your site.

I've seen this a number of times on various sites, it's just a technique to provide those button images that scale with the button. It could be an attack I suppose, but what's more concerning is that you have no idea where code comes from on a site that you manage. You need to be looking into source control, at the very least for stability of your website so you can revert back to older versions if something goes wrong, but also as a log of who added what when.

Bitbucket is good option for hosting closed source projects if you have a small team of developers, using Git.

As you can see in my edit, I actually decoded the base64 encoding for you. It seems to be harmless: http://www.w3schools.com/svg/svg_path.asp

  • Thanks all, This is actually a Fashion Brand site, I'm in charge of the E-Commerce, division. This code was over in the main Branding section where the CMS is modified by artists social media folks and anyone else with a login although there is a log. on the CMS and I'm certain a much more Extensive log in the Database but I've never messed with that.
