Description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Improper escaping in the document SkinsCode.XWikiSkinsSheet leads to an injection vector from view right on that document to programming rights, or in other words, it is possible to execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The attack works by opening a non-existing page with a name crafted to contain a dangerous payload. It is possible to check if an existing installation is vulnerable. See the linked GHSA for instructions on testing an installation. This issue has been patched in XWiki 14.4.8, 14.10.4 and 15.0-rc-1. Users are advised to upgrade. The fix commit d9c88ddc can also be applied manually to the impacted document SkinsCode.XWikiSkinsSheet and users unable to upgrade are advised to manually patch their installations.

Waratek protection

Mitigation candidate

A kind of vulnerability Waratek's rules address, with exploit code published or exploitation reported. No rule exists and none is planned yet. The decision below says what we found to build a rule from.

  • Protection none
  • Action unverified
  • Review automated Inferred
  • Record active
Decided by A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug
Finding A reference points at an upstream fix (commit tier): https://github.com/xwiki/xwiki-platform/commit/d9c88ddc4c0c78fa534bd33237e95dea66003d29. That makes this CVE a candidate for an ARMR patch rule — it is the kind of defect ARMR can address, and there is a fix to work from. No rule exists and none is scheduled: writing one means reading the linked change and finding a hook point ARMR can express it at, which may turn out not to exist.
