Sensitive-data disclosure via predictable transfer keys
Published Jun 16, 2022 · Updated Aug 3, 2024
Insufficient entropy in Broadcom CA Automic Workload Automation 12.2 and 12.3 allows remote attackers to decrypt sensitive agent traffic. The AutomationEngine generates AES transfer keys with predictable patterns and under 24 bits of observed entropy, then distributes them to agents for traffic encryption. An unauthenticated attacker must capture encrypted server traffic and brute-force the small key space; affected GSS modes are NO and LOCAL.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
