CVE-2026-25510 — AI Deep Analysis Summary

🚨 **Essence**: CI4MS < 0.28.5.0 has a critical code injection flaw. 📉 **Consequences**: Attackers can upload & execute arbitrary PHP code, leading to full **Remote Code Execution (RCE)** on the server.

🛡️ **Root Cause**: **CWE-434** (Unrestricted Upload of File with Dangerous Type). The file editor/saver endpoint fails to validate uploaded files, allowing malicious PHP scripts to be saved and executed.

🏢 **Affected**: **ci4-cms-erp / ci4ms**. 📦 **Version**: All versions **prior to 0.28.5.0**. If you are running 0.28.5.0 or later, you are safe!

💀 **Attacker Power**: With basic access, hackers gain **Full Control**. They can read sensitive data, modify system files, install backdoors, and pivot to other internal networks.…

🔓 **Threshold**: **Medium**. ⚠️ **Auth Required**: Yes, the attacker must be a **verified user** with **file editor permissions**. Not fully open to the public, but easy for insiders or compromised accounts.

📜 **Public Exp?**: Currently **No public PoC/Exploit** listed in the data. However, the CVSS score is **Critical (9.8)**, meaning the logic is straightforward for skilled attackers to develop quickly.

🔍 **Self-Check**: 1. Check your CI4MS version (must be < 0.28.5.0). 2. Audit user permissions: Do you have users with 'file editor' rights? 3. Scan for unexpected `.php` files in upload directories.

✅ **Fixed?**: **Yes**. The vendor released a fix in version **0.28.5.0**. 📝 **Patch**: Update immediately. See GitHub Advisory [GHSA-gp56-f67f-m4px] for details.

🚧 **No Patch?**: 1. **Revoke** 'file editor' permissions from all users immediately. 2. Disable the file upload/edit feature if possible. 3. Implement strict WAF rules to block PHP execution in upload folders.

🔥 **Urgency**: **CRITICAL**. 🚨 Despite requiring auth, the impact is **RCE**. Treat this as a **P0** incident. Update to v0.28.5.0 **TODAY** to prevent potential server takeover.
