Vulnerability Assessment

Weakness	CWE CWE-267 OWASP Top 10:2025 A06:2021 - Vulnerable and Outdated Components ASVS 5.0 V8 - Authorization Privilege defined with unsafe actions
Impact	An attacker with limited access can gain administrative or root privileges, enabling full control over the affected system. With a CVSS score of 4.1 (MEDIUM), this represents a moderate risk.
Exploit ScenarioDerived	A local attacker exploits a vulnerability in a privileged service or misconfigured permissions to escalate from a standard user to root/administrator.

AnalysisAIv1 – Mar 16, 2026

In Wing FTP Server through 7.4.4, the administrative web interface (listening by default on port 5466) runs as root or SYSTEM by default. The web application itself offers several legitimate ways to execute arbitrary system commands (i.e., through the web console or the task scheduler), and they are automatically executed in the highest possible privilege context. Because administrative users of the web interface are not necessarily also system administrators, one might argue that this is a privilege escalation. (If a privileged application role is not available to an attacker, CVE-2025-47812 can be leveraged.) NOTE: the vendor reportedly considers this behavior "fine to keep."

RemediationAI

Apply the principle of least privilege. Keep systems patched. Monitor for suspicious privilege changes. Use mandatory access controls (SELinux, AppArmor).
