Official description

XWiki Platform is a generic wiki platform. XWiki discovered that the patch for GHSA-5cf8-vrr8-8hjm was insufficient. Starting with version 6.2.1 and prior to versions 18.0.0RC1, 17.10.13, 17.4.9 and 16.10.17, 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. 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. As a workaround, the patch can be applied manually to the wiki page `XWiki.LiveTableResultsMacros`.

The underlying weakness: Exposure of Private Personal Information to an Unauthorized Actor

The product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected.

How developers prevent this class of flaw

  • Identify and consult all relevant regulations for personal privacy. An organization may be required to comply with certain federal and state regulations, depending on its location, the type of business it conducts, and the nature of any private data it handles. Regulations may include Safe Harbor Privacy Framework, Gramm-Leach Bliley Act (GLBA), Health Insurance Portability and Accountability Act (HIPAA), General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and others.
