Vulnerability details
FlyteAdmin is the control plane for the data processing platform Flyte. Users who enable the default Flyte’s authorization server without changing the default clientid hashes will be exposed to the public internet. In an effort to make enabling authentication easier…
more
for Flyte administrators, the default configuration for Flyte Admin allows access for Flyte Propeller even after turning on authentication via a hardcoded hashed password. This password is also set on the default Flyte Propeller configmap in the various Flyte Helm charts. Users who enable auth but do not override this setting in Flyte Admin’s configuration may unbeknownst to them be allowing public traffic in by way of this default password with attackers effectively impersonating propeller. This only applies to users who have not specified the ExternalAuthorizationServer setting. Usage of an external auth server automatically turns off this default configuration and are not susceptible to this vulnerability. This issue has been addressed in version 1.1.44. Users should manually set the staticClients in the selfAuthServer section of their configuration if they intend to rely on Admin’s internal auth server. Again, users who use an external auth server are automatically protected from this vulnerability.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Enables users to notice when hard-coded credentials have been exploited for unauthorized access.
Security training explicitly warns against hard-coded credentials, lowering their use in systems.
Policy and procedures prohibit hard-coded credentials in favor of managed authentication.
External identity providers eliminate the need for hard-coded credentials in applications.
Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.
Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.
Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.
Planned investment enables secure credential storage and management systems instead of hard-coded credentials.
