CVE-2023-37277Network attack vector

Remote code execution via tokenless REST POSTs

Published Jul 10, 2023 · Updated Nov 8, 2024

CSRF in XWiki Platform 1.8 through 14.10.7 and 15.0-rc-1 through 15.1 allows remote attackers to execute code via REST POSTs. The REST server accepts browser-simple POST content types and performs state-changing actions without validating an XWiki-Form-Token header. Exploitation requires a logged-in user's browser session with programming rights; successful script-macro execution compromises the entire installation.
