Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Arbitrary File Upload via `/admin/tinymce/upload`. <br>π₯ **Consequences**: Attackers upload malicious PHP files β‘οΈ **Remote Code Execution (RCE)**. Total system compromise possible.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Lack of strict validation on file uploads in the TinyMCE editor endpoint. <br>β **Flaw**: Allows execution of server-side scripts (PHP) disguised as uploads.
π΅οΈ **Hacker Actions**: Execute arbitrary code on the server. <br>π **Privileges**: Full control over the CRM environment. <br>π **Data**: Access to all customer/business data stored in the CRM.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Medium. <br>β **Auth Required**: Yes, **Authenticated** access needed. <br>βοΈ **Config**: Low complexity (AC:L). No user interaction required (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: Public PoC available on GitHub (TREXNEGRO). <br>β οΈ **Risk**: Easy to reproduce. Wild exploitation is likely given the simplicity.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: <br>1. Verify version is **v2.2.x**. <br>2. Check if `/admin/tinymce/upload` endpoint exists. <br>3. Scan for uploaded `.php` files in upload directories.
π§ **No Patch?**: <br>1. **Disable** the TinyMCE upload feature if possible. <br>2. **Restrict** access to `/admin/` routes via WAF. <br>3. **Block** `.php` file extensions in upload filters.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. <br>π **CVSS**: 9.8 (Critical). <br>β³ **Action**: Patch immediately. Authenticated RCE is a critical threat to business data.
