XWiki Blog Application: Privilege Escalation (PR) from account through blog content
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.xwiki.contrib.blog:application-blog-ui | < 9.14 | 9.14 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
The blog application in XWiki allowed remote code execution for any user who has edit right on any page. Normally, these are all logged-in users as they can edit their own user profile. To exploit, it is sufficient to add an object of type `Blog.BlogPostClass` to any page and to add some script macro with the exploit code to the "Content" field of that object.
### Patches
The vulnerability has been patched in the blog application version 9.14 by executing the content of blog posts with the rights of the appropriate author.
### Workarounds
We're not aware of any workarounds.
