CVE-2025-32977Network attack vector

Unauthenticated malicious backup upload via signature-validation weakness

Published Jun 24, 2025 · Updated Nov 3, 2025

Improper signature verification in affected Quest KACE SMA 13.0.x through 14.1.x releases allows remote attackers to upload malicious backups. The backup upload validation process accepts malicious backup content despite performing cryptographic signature checks; the precise validation error is undisclosed. No account is required, but exploitation requires user interaction and can inject malicious data that compromises appliance integrity.
