CVE-2023-30516: Jenkins Image Tag Parameter Plugin improperly introduces option to opt out of SSL/TLS certificate validation

Jenkins Image Tag Parameter Plugin 2.0 improperly introduces an option to opt out of SSL/TLS certificate validation when connecting to Docker registries.

Job configurations using Image Tag Parameters that were created before 2.0 will have SSL/TLS certificate validation disabled by default.

Root Cause Analysis

The vulnerability stems from two key points: (1) the introduction of an optional SSL/TLS bypass in version 2.0, and (2) insecure defaults for legacy configurations. The first function is inferred to handle registry connections with conditional SSL validation(), making it directly responsible for the improper certificate validation(). The second function is hypothesized to handle backward compatibility for job configurations, where the absence of explicit SSL validation() settings in pre-2.0 jobs would lead to insecure defaults. While exact function names/paths are unavailable, these are common patterns in Jenkins plugin vulnerabilities involving configuration defaults and SSL handling.
