CVE-2015-5082 — AI Deep Analysis Summary

🚨 **Essence**: A Command Injection flaw in Endian Firewall. 📉 **Consequences**: Remote attackers can execute arbitrary OS commands via shell metacharacters. 💥 **Impact**: Full system compromise possible.

🛡️ **Root Cause**: Insufficient input validation in `cgi-bin/chpasswd.cgi`. 🐛 **Flaw**: The script fails to sanitize `NEW_PASSWORD_1` and `NEW_PASSWORD_2` parameters. 🚫 **Result**: Malicious input is executed as code.

📦 **Product**: Endian Firewall (Unified Risk Management Tool). 🐧 **Base**: Red Hat Enterprise Linux. 📅 **Affected**: Versions **prior to 3.0**. ⚠️ **Note**: Vendor listed as 'n/a' in data.

👑 **Privileges**: Remote attackers gain the ability to run commands. 🗝️ **Data**: Potential access to all system data/files. 🌐 **Scope**: Can leverage shell metacharacters for arbitrary execution.

🔓 **Threshold**: Likely Low/Medium. 🌍 **Access**: Remote exploitation is possible. 🔑 **Auth**: Data implies remote access to the CGI interface, but specific auth requirements aren't detailed in the snippet.…

💣 **Public Exp**: YES. 📚 **Sources**: Exploit-DB (IDs 37428, 38096, 37426) and PacketStorm. 🛠️ **Tools**: Metasploit module available (`linux/http/efw_chpasswd_exec`). 🔥 **Status**: Wild exploitation is feasible.

🔍 **Check**: Scan for `cgi-bin/chpasswd.cgi` endpoint. 🧪 **Test**: Inject shell metacharacters into `NEW_PASSWORD_1`/`2` fields. 📡 **Scan**: Use Nessus or Nmap scripts targeting Endian Firewall versions < 3.0.…

🩹 **Fix**: Upgrade to Endian Firewall **version 3.0 or later**. ✅ **Official**: The description explicitly states the flaw exists in versions *before* 3.0. 🔄 **Action**: Apply vendor patches immediately.

🚧 **Workaround**: If patching is delayed, restrict network access to the management interface. 🛑 **Block**: Deny external traffic to `cgi-bin/chpasswd.cgi`.…

🔥 **Urgency**: HIGH. 🚨 **Reason**: Remote Code Execution (RCE) with public exploits. 📉 **Risk**: Critical impact on confidentiality and integrity. ⏳ **Action**: Patch immediately. Do not ignore.
