html injection in plone 2.5 comments

Reported by: linqueur Owned by: dannyb
Priority: blocker Milestone: 2.1.4
Component: General Version:
Keywords: html injection, discussions, comments Cc:


By default comments (former discussions) in plone 2.5 seem to accept html code, s.t. <script>alert('This is an alertbox')</script> is executed when viewing. I posted this on gmane.comp.web.zope.plone.user and got the following answer by Alexander Limi:

By default, Plone comments should be plain text, not HTML - if somebody changed that, they screwed up. :)

Please file a bug at  http://dev.plone.org/plone and mention what I said above.

I cannot reproduce this in 2.5 svn. HTML input is quoted, no tags are rendered. Do you have some 3rd party product installed that may be responsible for this.

I am a newbee to plone and zope, so I dont know how to give you effective information about my installation. I installed the linux download version from plone.org at 2006-07-28 called Plone2.5-UnifiedInstaller-r2.tgz. After unpacking the date of the directory Plone2.5-UnifiedInstaller was 2006-07-07. I think your question about installed 3rd party products could be answered by the install tab of the portal_quickinstaller in the ZMI, so this is what follows:

Installable Products

Product Name Version CMFSquidTool 1.3.0 CacheSetup 1.0 Marshall 0.6.5-final PloneErrorReporting 0.11 PloneLanguageTool 1.3 TextIndexNG3 3.1.9

I hope this helps. Let me know if you need other information.

And you haven't customized any templates or scripts, I presume?

  • Owner changed from somebody to dannyb

comment:7 Changed 10 years ago by linqueur

No change. I changed the logo now, but injection was possible right at the beginnig. The only interesting thing I did after following the installation guide of plone documentation was to allow discussions on every item. Do you want an example injected page attached too?

comment:8 Changed 10 years ago by linqueur

I will attach the source of an injected page know. It is interesting that the comment of admin is filtered while the comments of the owner and another user not.

comment:9 Changed 10 years ago by alecm

That's indeed very interesting.

comment:10 Changed 10 years ago by linqueur

I reproduced the problem with a completely fresh installation. Just installed, added a plone site, added a user who added a plone page where discussions are allowed and had the same result like before (owner was able to inject html, admin not).

comment:11 Changed 10 years ago by alecm

  • Status changed from new to closed
  • Resolution set to fixed

(In [10409]) DiscussionTool.cookReply needs to be available to anyone who can comment on an item, otherwise the comment will not be cooked and we get HTML injection. This fixes #5718
