Q: Who is affected? (Versions/Components)

📦 **Affected**: ClamAV versions **prior to 0.91.2**. 📧 **Component**: Specifically the `clamav-milter` service when operating in **Black Hole Mode**. 🏢 **Vendor**: ClamAV Project.

Q: What can hackers do? (Privileges/Data)

💀 **Hackers' Power**: Execute **arbitrary system commands** with the privileges of the service user (often root or mail user). 🔓 **Impact**: Full server compromise, data theft, or lateral movement. 🕵️♂️

Q: Is exploitation threshold high? (Auth/Config)

🔓 **Threshold**: **LOW**. 🌐 **Auth**: No authentication required; exploits via standard **SMTP RCPT TO** headers. ⚙️ **Config**: Requires the target to be running ClamAV Milter in Black Hole Mode. 📡

Q: Is there a public Exp? (PoC/Wild Exploitation)

💣 **Public Exp**: **YES**. 🐍 **PoC**: Python-based RCE exploits available on GitHub (e.g., `0x1sac`, `strikoder`). 🌍 **Status**: Wild exploitation is possible due to simple SMTP vector. 🚩

Q: How to self-check? (Features/Scanning)

🔍 **Check**: Scan for ClamAV Milter services. 📋 **Verify**: Check version number (`clamav-milter -v`). 🚫 **Flag**: If version < 0.91.2 and Black Hole Mode is active, you are vulnerable. 📊

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed**: **YES**. 📦 **Patch**: Upgrade to **ClamAV 0.91.2** or later. 📜 **Advisories**: Debian DSA-1366, Mandriva MDKSA-2007:172, Fedora FEDORA-2007-2050. 🔄

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. 🚨 **Priority**: Patch immediately. 📉 **Risk**: Remote, unauthenticated RCE via common protocol (SMTP). 🏃♂️ **Action**: Update ClamAV Milter to v0.91.2+ NOW. ⏳
