Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: SSRF in `upload.php` via the `url` parameter.β¦
π‘οΈ **Root Cause**: Server-Side Request Forgery (SSRF). The application fails to properly validate user-supplied URLs in the upload functionality, allowing malicious redirection.
Q3Who is affected? (Versions/Components)
π― **Affected**: Responsive FileManager **v9.13.1**. Specifically the `upload.php` component. It is a PHP-based open-source file manager.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Can perform SSRF attacks. This allows probing internal services, bypassing firewalls, or potentially accessing sensitive internal data through the server's perspective.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Likely **Low**. Since it involves a file upload script (`upload.php`), attackers often just need to upload a file or interact with the upload interface. No complex authentication bypass mentioned.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: **Yes**. Exploit-DB ID **45103** is available. Proof-of-concept templates exist in Nuclei (ProjectDiscovery). Wild exploitation is possible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `upload.php` in Responsive FileManager installations. Look for the `url` parameter in upload requests. Use Nuclei templates for automated detection.
π **Workaround**: Disable the `upload.php` functionality if not needed. Implement strict WAF rules to block SSRF payloads in the `url` parameter. Restrict server outbound network access.
Q10Is it urgent? (Priority Suggestion)
β οΈ **Urgency**: **High**. Public exploits exist (Exploit-DB 45103). SSRF is a critical risk. Immediate monitoring and mitigation are recommended despite the lack of a specific patch note.
