Summary
XWiki Affected by Reflected Cross-Site Scripting (XSS) in Error Messages
Details

Impact

A reflected cross site scripting (XSS) vulnerability in XWiki allows an attacker to execute arbitrary actions in XWiki with the rights of the victim if the attacker manages to trick a victim into visiting a crafted URL. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation.

Patches

This vulnerability has been patched in XWiki 17.8.0RC1, 17.4.5 and 16.10.12.

Workarounds

The patch can be applied manually, only a single line in templates/logging_macros.vm needs to be changed, no restart is required.
