Summary

The CC27xx Debug Authentication can be bypassed if both the configurations below are simultaneously enabled:

  1. Debug Authentication Mode is enabled in CCFG
  2. Tools Client Mode is enabled in both CCFG and SCFG

Note 1: If Tools Client Mode is enabled in only one of the two configuration modes (CCFG or SCFG), then this vulnerability does not occur. The recommended mitigation below reflects this fact.

Note 2: This vulnerability is not applicable and does not impact customer systems if customers have followed the guidance outlined in the CC27xx Technical Reference Manual Section 10.1 Securely Configuring Your Device which includes instructions in Section 10.1.4 to disable Tools Client Mode. This guidance also appears in Section 9.1.5 Flashless Test Mode and Tools Client Mode which addresses measures to establish the most secure configuration.
