CVE-2026-42779 — AI Deep Analysis Summary

🚨 **Essence**: A Remote Code Execution (RCE) flaw in Apache MINA. The `resolveClass()` method has a branch for static/basic types that **skips class name validation**.…

🛡️ **Root Cause**: **CWE-502** (Deserialization of Untrusted Data). The fix for CVE-2026-41635 was **not applied** to older branches.…

📦 **Affected**: Apache MINA versions **2.1.0 to 2.1.11** AND **2.2.0 to 2.2.6**. 📢 **Impact**: Any application using Apache MINA that calls `IoBuffer.getObject()` is vulnerable. 🏢 **Vendor**: Apache Software Foundation.

💀 **Hacker Power**: Full **Remote Code Execution (RCE)**. With CVSS 9.8 (Critical), attackers gain **High** Confidentiality, Integrity, and Availability impact. They can run **any code** they want on the target system.…

⚡ **Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. 🌐 Network accessible, Low complexity, **No Privileges** required, **No User Interaction** needed. It is a nightmare scenario for attackers. 😱

🕵️ **Public Exploit**: The `pocs` field is **empty** in the data. 🚫 No public PoC or wild exploitation code is currently available. However, the logic flaw is clear, so custom exploits are likely trivial to write. ⚠️

🔍 **Self-Check**: Scan your environment for **Apache MINA** libraries. 🧐 Specifically check if your app uses `IoBuffer.getObject()`. Verify the version is **< 2.1.12** or **< 2.2.7**. 📋

✅ **Official Fix**: **YES**. The vulnerability is fixed in **Apache MINA 2.1.12** and **2.2.7**. 🛠️ The solution applies the class name whitelist **earlier** in the process, before `Class.forName()` is called. 🔄

🚧 **No Patch?**: If you cannot upgrade immediately, you must **disable or restrict** the usage of `IoBuffer.getObject()`.…

🔥 **Urgency**: **CRITICAL**. Priority: **IMMEDIATE**. 🚨 CVSS 9.8 + RCE + No Auth Required = High Risk. Upgrade to 2.1.12/2.2.7 **NOW** to prevent potential server compromise. ⏳
