CVE-2023-24495Network attack vector

Privileged internal-service access via unvalidated session input

Published Jan 25, 2023 · Updated Mar 27, 2025

SSRF in Tenable.sc 5.23.1 and earlier allows remote authenticated users to access internal and external services through crafted input. Tenable attributes the flaw to improper validation of session and user-accessible input but has not disclosed the affected endpoint or validation operation. A privileged account is required; the server can covertly interact with reachable services and expose response-derived information.
