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)
