GHSA-6gvj-8vc5-8v3j: org.xwiki.platform:xwiki-platform-oldcore Open Redirect vulnerability
Impact
It’s possible to exploit well known parameters in XWiki URLs to perform redirection to untrusted site. This vulnerability was partially fixed in the past for XWiki 12.10.7 and 13.3RC1 but there is still the possibility to force specific URLs to skip some checks, e.g. using URLs like http:example.com in the parameter would allow the redirect.
Patches
The issue has now been patched against all patterns that we know about for performing redirect. It also performs a real URI parsing that should protect in most cases. This has been patched in XWiki 14.10.4 and 15.0.
Workarounds
The only workaround is to upgrade XWiki.
