CVE-2024-24552Public exploitNetwork attack vector

Account impersonation via unchanged post-login session ID

Published Jun 24, 2024 · Updated Aug 1, 2024

Session fixation in Bludit 3.15.0 and earlier allows attackers to impersonate a user after that user signs in with a fixed session ID. The /admin/ login flow sets a BLUDIT-KEY cookie but does not replace its value after authentication, so the attacker's known identifier becomes privileged. The attacker must first make the victim's browser use that identifier, and the victim must then sign in; the result is account impersonation.
