CVE-2023-29525: Privilege escalation from view right on XWiki.Notifications.Code.LegacyNotificationAdministration in xwiki-platform

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 58/100)

  • 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: 77.7% (FIRST EPSS); higher than 99.5% 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-distribution-war (Maven) 13.10.11, 14.4.8, 14.6-rc-1; org.xwiki.platform:xwiki-platform-legacy-events-hibernate-ui (Maven) 14.10.3.

Add it to your regular patch cycle. Upgrade to org.xwiki.platform:xwiki-platform-distribution-war (Maven) 13.10.11, 14.4.8, 14.6-rc-1; org.xwiki.platform:xwiki-platform-legacy-events-hibernate-ui (Maven) 14.10.3 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. Affected versions of xwiki are subject to code injection in the `since` parameter of the `/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration` endpoint. This provides an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. Users are advised to upgrade. Users unable to upgrade may modify the page `XWiki.Notifications.Code.LegacyNotificationAdministration` to add the missing escaping. For versions < 14.6-rc-1 a workaround is to modify the file `<xwikiwebapp>/templates/distribution/eventmigration.wiki` to add the missing escaping.
