CVE-2025-27027Network attack vector

Full shell access via rbash restriction bypass

Published Jul 9, 2025 · Updated Jul 9, 2025

Improper isolation in Radiflow iSAP Smart Collector before 3.02-1 allows remote authenticated users to obtain a full Linux shell over SSH. The vpuser SSH session invokes rbash with a command allowlist, but ENISA has not disclosed which permitted command or shell behavior breaks confinement. Valid vpuser credentials are required; exploitation escapes the command allowlist but does not establish administrative privilege.
