CVE-2012-2714Network attack vector

Account hijacking via unvalidated assertion audience

Published Jan 9, 2020 · Updated Aug 6, 2024

Authentication bypass in Mozilla Persona before 7.x-1.3 allows remote attackers to hijack arbitrary Drupal users via an assertion audience. The BrowserID login handler accepts an assertion audience without binding it to a trusted audience configured by the relying site. A victim must authenticate to a malicious BrowserID site, after which that site can reuse the identity to impersonate the victim on an affected Drupal site.
