Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 have an improperly implemented security check, allowing a token to be accepted under certain conditions. Token validation is incomplete, potentially allowing a token to be used for an unintended purpose.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Attack conditions

Under certain conditions, token validation is incomplete, so a token may be accepted for a purpose it was not intended for.
