CRITICAL 9.3

DescriptionCVE.org

ReQuest Serious Play F3 Media Server 7.0.3 contains an unauthenticated remote code execution vulnerability that allows attackers to execute arbitrary commands as the web server user. Attackers can upload PHP executable files via the Quick File Uploader page, resulting in remote code execution on the server.

Analysis

Technical ContextAI

Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells. This vulnerability is classified as OS Command Injection (CWE-78).

RemediationAI

Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
