CVE-2024-43400: XWiki Platform allows XSS through XClass name in string properties

MediumCVSS 5.4 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.48% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: org.xwiki.platform:xwiki-platform-oldcore (Maven) 14.10.21, 15.5.5, 15.10.6.
  • Severity is disputed: the assigning authority (CNA) scores it 9.1, NVD 5.4.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to org.xwiki.platform:xwiki-platform-oldcore (Maven) 14.10.21, 15.5.5, 15.10.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It is possible for a user without Script or Programming rights to craft a URL pointing to a page with arbitrary JavaScript. This requires social engineer to trick a user to follow the URL. This has been patched in XWiki 14.10.21, 15.5.5, 15.10.6 and 16.0.0.
