CVE-2025-0411 — AI Deep Analysis Summary

🚨 **Essence**: 7-Zip fails to propagate the 'Mark-of-the-Web' (MotW) to extracted files. 📦 💥 **Consequences**: Attackers bypass security warnings. Victims unknowingly execute malicious code in their local environment. 🏠

🔍 **CWE**: CWE-693 (Protection Mechanism Failure). 🛡️ ⚙️ **Flaw**: The software logic ignores the security tag when unpacking archives. The 'safety seal' is lost during extraction. 🔓

👥 **Vendor**: 7-Zip. 📂 📅 **Affected**: Versions **before 24.09**. 📉 ✅ **Fixed**: Version 24.09 and later are safe. 🆙

🕵️ **Action**: Remote Code Execution (RCE). 💻 🔑 **Privilege**: Runs as the **current user**. 👤 📊 **Impact**: Full control over the user's environment. No admin rights needed. 🚀

🚶 **Threshold**: Medium. 🚶‍♂️ 🖱️ **Requirement**: **User Interaction** is mandatory. 🖱️ 📩 **Trigger**: Victim must open a crafted archive or visit a malicious page. 📧

🔓 **Exploit**: YES. Public PoCs exist. 📂 🌐 **Sources**: GitHub repositories (e.g., dhmosfunk, iSee857). 💻 📝 **Method**: Compile loader.exe, compress with 7-Zip, send to victim. 📦

🔎 **Check**: Scan for 7-Zip versions < 24.09. 📊 📂 **Indicator**: Look for extracted files **missing** the MotW attribute. 🏷️ 🛠️ **Tool**: Use the provided GitHub POCs for testing (in isolated envs!). 🧪

🩹 **Fix**: Upgrade to **7-Zip 24.09+**. 🆙 📥 **Action**: Download from official site. 🌐 ✅ **Result**: MotW is now correctly propagated. 🛡️

🚧 **Workaround**: If you can't update: 🚫 1. **Disable** 7-Zip if unnecessary. 📵 2. **Educate** users to check file properties before opening. 👀 3. Use **Alternative** archivers with better MotW support. 🔄

🔥 **Priority**: HIGH. 🔥 ⚠️ **Reason**: CVSS 7.0 (High). 📈 🎯 **Urgency**: Easy to exploit via social engineering. 📧 🚀 **Action**: Patch immediately! 🏃‍♂️
