CVE-2024-11856Network attack vector

Unauthenticated password guessing via unenforced attempt limit

Published Dec 2, 2024 · Updated Dec 2, 2024

Credential-protection failure in HPE IceWall certd allows remote attackers to exceed the configured password-attempt limit. The certd authentication module continues processing failed password attempts after the administrator-defined threshold is reached. No credentials or user interaction are required, and the bypass enables continued password guessing without directly disclosing data or interrupting service.
