CVE-2015-7857 — AI Deep Analysis Summary

🚨 **Essence**: A critical **SQL Injection (SQLi)** flaw in Joomla! CMS. 📉 **Consequences**: Attackers can execute **arbitrary SQL commands**, potentially leading to full system compromise or data theft. 💥

🛠️ **Root Cause**: The `getListQuery` function in `administrator/components/com_contenthistory/models/history.php` fails to properly sanitize input.…

🎯 **Affected**: Joomla! versions **3.2 through 3.4.5** (specifically prior to 3.4.5). 📦 **Component**: The `com_contenthistory` module in the administrator backend. ⚠️

🕵️ **Capabilities**: Hackers can run **any SQL command**. 🗄️ **Impact**: Access to database contents, user credentials, or even remote code execution (RCE) via SQLi techniques. 🔓

🔓 **Threshold**: **Low**. It is a **Remote** vulnerability. 🌐 No authentication is explicitly required in the description for the injection point, making it highly accessible to attackers. 🚀

💣 **Exploitation**: **Yes**. Public exploits and PoCs exist (e.g., Rapid7 Metasploit module, PacketStorm files). 📂 Wild exploitation is possible. 🔥

🔍 **Self-Check**: Scan for Joomla! versions < 3.4.5. 🕵️‍♂️ Look for the `com_contenthistory` component. 🛠️ Use SQLi scanners targeting the `list[select]` parameter in history requests. 📡

🛡️ **Fix**: **Yes**. Upgrade Joomla! to version **3.4.5 or later**. 🔄 The vendor (Open Source Matters) released patches to address this filtering issue. ✅

🚧 **Workaround**: If patching is delayed, restrict access to the `/administrator/` path via firewall/WAF. 🧱 Disable the `com_contenthistory` component if not needed. 🚫

🔴 **Priority**: **HIGH**. 🚨 Remote code execution potential + public exploits = Immediate action required. 🏃‍♂️ Patch immediately to prevent data breach. ⏳
