Froxlor 0.10.0 before 2.3.14 Newline Injection via Ftps.add additional_members

Assigner: VulnCheck
Reserved: 13.10.2026 Published: 13.10.2026 Updated: 13.10.2026

Froxlor 0.10.0 before 2.3.14 contains a newline injection vulnerability that allows authenticated customers to inject arbitrary entries into the root-owned NSS group database via the unvalidated additional_members parameter of the Ftps.add API. Attackers can embed newline characters that the REBUILD_NSSUSERS cron writes unsanitized into /var/lib/extrausers/group, creating privileged group entries for local privilege escalation.
