Package Slug

Vulnerability

Missing Authentication for Critical Function

Description

In ectd before versions 3.4.10 and 3.3.23, gateway TLS authentication is only applied to endpoints detected in DNS SRV records. When starting a gateway, TLS authentication will only be attempted on endpoints identified in DNS SRV records for a given domain, which occurs in the discoverEndpoints function. No authentication is performed against endpoints provided in the --endpoints flag. This has been fixed in versions 3.4.10 and 3.3.23 with improved documentation and deprecation of the functionality.

Affected Versions

All versions before 3.3.23, all versions starting from 3.4.0-rc.0 up to 3.4.9

Solution

Upgrade to versions 3.3.23, 3.4.10 or above.
