Sources and claim methodology

Upstream source description

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.
