    The following components are affected:

    * FTL Server (tibftlserver)
    * Docker images containing tibftlserver


    Description

    The components listed above contain a vulnerability that theoretically allows
    a non-administrative, authenticated FTL user to trick the affected components
    into creating illegitimate certificates. These maliciously generated
    certificates can be used to enable man-in-the-middle attacks or to escalate
    privileges so that the malicious user has administrative privileges.


    Impact

    The impact of this vulnerability includes the theoretical possibility that a
    malicious non-administrative user can gain full administrative access to the
    affected system.

    CVSS v3 Base Score: 7.5 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
