Default authentication behavior vulnerable to session fixation attacks

    XMLWordPrintable

Details

    Description

      See: https://www.owasp.org/index.php/Session_Fixation

      In JBossWeb, there was a system property to enable this behavior: org.apache.catalina.authenticator.AuthenticatorBase.CHANGE_SESSIONID_ON_AUTH

      Undertow does not seem to have an equivalent. I don't see any reason not to always force a session ID change following successful authentication when HttpSession.isNew() returns false.

          causes

          Bug - A problem that impairs or prevents the functions of the product. WFLY-5663 Default authentication behavior vulnerable to session fixation attacks

          • Critical - To be worked on immediately following BLOCKER issues.
          • Closed

          Bug - A problem that impairs or prevents the functions of the product. WFLY-5711 FormAuthenticationWebFailoverTestCase fails against Undertow 1.3.6.Final

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
