Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: CuteFlow's `restart_circulation_values_write.php` fails to validate file types. π **Consequences**: Attackers can upload arbitrary files, leading to **Remote Code Execution (RCE)**.β¦
π‘οΈ **CWE-434**: Unrestricted Upload of File with Dangerous Type. π **Flaw**: The script accepts files without checking extensions or content, allowing malicious payloads to bypass security controls.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: CuteFlow.org. π¦ **Product**: CuteFlow (Web-based document workflow tool). π **Affected**: Versions **2.11.2 and earlier**. β οΈ Newer versions may be patched.
Q4What can hackers do? (Privileges/Data)
π» **Privileges**: Full Remote Code Execution (RCE). π **Data**: Complete access to server files, database, and user data.β¦
π **Threshold**: Likely **Low**. Since it involves file upload via a web script, it often requires only basic user access or even anonymous access depending on configuration.β¦
π₯ **Yes**. Metasploit module exists (`multi/http/cuteflow_upload_exec.rb`). π Public advisories and technical descriptions are available. Wild exploitation is highly probable due to ease of use.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for `restart_circulation_values_write.php`. π‘ **Tools**: Use Metasploit or Nmap scripts targeting CuteFlow. π **Verify**: Look for version 2.11.2 or older in the HTTP headers or footer.
π§ **Workaround**: If patching is impossible, **disable** the `restart_circulation_values_write.php` script. π« **Restrict**: Block access to the upload directory via WAF or firewall rules.β¦
β‘ **Priority**: **CRITICAL**. RCE via simple file upload is a high-impact, low-effort attack. π¨ **Urgency**: Patch immediately. This is a known, exploitable vulnerability with public tools available. Don't wait!
