CVE-2023-37913: org.xwiki.platform:xwiki-platform-office-importer vulnerable to arbitrary server side file writing from account through office converter

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: 1.3% (FIRST EPSS); higher than 72% 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-office-importer (Maven) 15.3-rc-1, 14.10.8.

Low priority for now. Upgrade to org.xwiki.platform:xwiki-platform-office-importer (Maven) 15.3-rc-1, 14.10.8 or later.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. There are no known workarounds apart from disabling the office converter.
