XWiki Platform vulnerable to privilege escalation via async macro and IconThemeSheet from the user profile

Impact

One can execute any wiki content with the right of IconThemeSheet author by creating an icon theme with the following content:

}}}
{{async async="true"}}
{{groovy}}
  println("Hello from Groovy!")
{{/groovy}}
{{/async}}
{{{

Can be done by creating a new page or even through the user profile for users not having edit right.

Patches

This has been patched in XWiki 14.9, 14.4.6, and 13.10.10.

Workarounds

An easy workaround is to actually fix the bug in the page IconThemesCode.IconThemeSheet by applying the following modification: https://github.com/xwiki/xwiki-platform/commit/48caf7491595238af2b531026a614221d5d61f38#diff-2ec9d716673ee049937219cdb0a92e520f81da14ea84d144504b97ab2bdae243R45
