CVE-2024-31981: XWiki Platform: Privilege escalation (PR) from user registration through PDFClass

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.4% (FIRST EPSS); higher than 73.6% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: org.xwiki.platform:xwiki-platform-oldcore (Maven) 15.5.4, 15.10-rc-1, 14.10.20.

Low priority for now. Upgrade to org.xwiki.platform:xwiki-platform-oldcore (Maven) 15.5.4, 15.10-rc-1, 14.10.20 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

XWiki Platform is a generic wiki platform. Starting in version 3.0.1 and prior to versions 4.10.20, 15.5.4, and 15.10-rc-1, remote code execution is possible via PDF export templates. This vulnerability has been patched in XWiki 14.10.20, 15.5.4 and 15.10-rc-1. If PDF templates are not typically used on the instance, an administrator can create the document `XWiki.PDFClass` and block its edition, after making sure that it does not contain a `style` attribute. Otherwise, there are no known workarounds aside from upgrading.
