CVE-2026-42084 · OpenC3 COSMOS: Hijacked session token can be used to reset password for persistence
Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.
OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, the OpenC3 password change functionality allows a user to change their password without providing the old password, by accepting a valid session token instead. In assumed breach scenarios, this behaviour can be exploited by an attacker who has already obtained a valid session token, to gain persistence in hijacked account (including admin) and prevent legitimate users from accessing the account. This issue has been patched in versions 6.10.5 and 7.0.0-rc3.
