Summary

Cisco UCS Invicta appliances running versions 4.3, 4.5, and 5.0.1, as well as the Invicta Scaling System, are affected by a significant cryptographic vulnerability. This flaw arises from the use of a hardcoded GnuPG encryption key shared across multiple customer installations. Attackers can exploit this weakness by capturing network traffic sent to an Autosupport server, using the known key from a different installation to bypass encryption protections. This security gap has been documented under Bug ID CSCur85504, highlighting the risks associated with improper cryptographic management.
