Description
Impact
XWiki discovered that the patch for GHSA-5cf8-vrr8-8hjm was insufficient and with slightly modified parameters to the LiveTableResults, it is still possible to discover password hashes one bit at a time, so with 768 requests, the full password salt and hash can be retrieved of a user.
Patches
The check for password (and email properties) has been adjusted in XWiki 18.0.0RC1, 17.10.13, 17.4.9 and 16.10.17.
Workarounds
The patch can be applied manually to the wiki page XWiki.LiveTableResultsMacros.
