Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: **YES**. Exploit-DB ID **48780** is available. π **Status**: Active exploitation is possible for anyone with the PoC.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Mara CMS 7.5** instances. π **Indicator**: Look for writable `codebase/handler.php` or similar upload endpoints. Use DAST tools to test file upload validation.
π **Workaround**: **Disable file uploads** if not needed. π« **Restrict Access**: Block external access to `codebase/` directory via WAF or Nginx/Apache config. Whitelist allowed file extensions.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: Immediate action required. RCE via unauthenticated upload is a high-severity threat. Patch or isolate immediately.
