Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Froxlor 0.10.0 至 2.3.14 版本之前存在换行符注入漏洞，允许已认证的客户通过 Ftps.add API 中未经验证的 additional_members 参数，向拥有 root 权限的 NSS 组数据库中注入任意条目。攻击者可嵌入换行符，这些换行符会被 REBUILD_NSSUSERS cron 任务以未过滤的形式写入 /var/lib/extrausers/group 文件，从而创建特权组条目，实现本地提权。

Froxlor 0.10.0 before 2.3.14 Newline Injection via Ftps.add additional_members
Source: CVE Program / CVE List V5
Vulnerability Description
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.
