CVE-2023-50722Network attack vector

Remote code execution via unescaped space parameter

Published Dec 15, 2023 · Updated Aug 2, 2024

Cross-site scripting in XWiki Platform before 14.10.15, 15.5.2, and 15.7-rc-1 allows remote attackers to execute code through a crafted URL. The XWiki.ConfigurableClass template inserts the current document space into an admin-section link without URL encoding, letting crafted syntax escape the parameter context. Execution requires an administrator with edit rights on a configuration section to load the URL, after which injected XWiki code runs with programming rights and can control the installation.
