CVE-2023-45135Public exploitNetwork attack vector

Victim-assisted code execution via hidden page title

Published Oct 25, 2023 · Updated Sep 10, 2024

Code injection in XWiki Platform before 14.10.12 and in the 15.x branch before 15.5-rc-1 allows remote authenticated users to execute code. The create action accepts a title expression in the first-step request, hides that value from the confirmation page, and evaluates it after Create is clicked. Exploitation requires a victim to open the crafted link and click Create; script or programming rights then bound execution to browser scripts or full server code.
