HUBzero CMS through 2.2.32 accepts session identifiers from query strings and request variables instead of cookies alone, allowing unauthenticated attackers to fixate victim sessions. Attackers can obtain a valid session identifier, send victims a crafted link containing it, and replay the identifier after the victim authenticates to hijack their account and access.
