CVE-2026-42778 β€” AI Deep Analysis Summary

CVSS 9.8 Β· Critical

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: A critical deserialization flaw in Apache MINA. The security fix for CVE-2024-52046 was incomplete in older branches. πŸ“‰ **Consequences**: Attackers can execute arbitrary code remotely.…

Q2Root Cause? (CWE/Flaw)

πŸ›‘οΈ **CWE**: CWE-502 (Deserialization of Untrusted Data). πŸ” **Flaw**: The class name whitelist validation is applied too late.…

Q3Who is affected? (Versions/Components)

πŸ“¦ **Product**: Apache MINA. πŸ“… **Affected Versions**: β€’ 2.1.0 – 2.1.11 β€’ 2.2.0 – 2.2.6 ⚠️ **Note**: Versions 2.1.12 and 2.2.7 are SAFE.

Q4What can hackers do? (Privileges/Data)

πŸ’₯ **Impact**: Full Remote Code Execution (RCE). πŸ“Š **CVSS**: 9.8 (Critical). πŸ•΅οΈ **Privileges**: No authentication required. Attackers can read, modify, and delete data, plus take full control of the affected system.

Q5Is exploitation threshold high? (Auth/Config)

πŸ”“ **Threshold**: LOW. 🌐 **Network**: Attack vector is Network (AV:N). πŸ”‘ **Auth**: None required (PR:N). πŸ–±οΈ **User Interaction**: None required (UI:N). This is an easy, automated exploit.

Q6Is there a public Exp? (PoC/Wild Exploitation)

🚫 **Public Exploit**: No PoC or wild exploitation data provided in the source. πŸ“ **Status**: While no code is public, the logic flaw is clear. High risk of future exploitation due to low barrier to entry.

Q7How to self-check? (Features/Scanning)

πŸ” **Check**: Scan for Apache MINA usage. πŸ“‘ **Indicator**: Look for applications calling `IoBuffer.getObject()`. πŸ“‹ **Version Audit**: Verify if your MINA version falls within the 2.1.x (pre-12) or 2.2.x (pre-7) ranges.

Q8Is it fixed officially? (Patch/Mitigation)

βœ… **Fixed**: YES. πŸ› οΈ **Solution**: Upgrade to Apache MINA **2.1.12** or **2.2.7**. The fix moves the whitelist check *before* static initialization, closing the race condition.

Q9What if no patch? (Workaround)

🚧 **No Patch?**: If you cannot upgrade immediately, you must avoid calling `IoBuffer.getObject()` with untrusted data.…

Q10Is it urgent? (Priority Suggestion)

πŸ”₯ **Urgency**: CRITICAL. πŸš€ **Priority**: Patch IMMEDIATELY. With a CVSS of 9.8 and no auth needed, this is a high-priority target for attackers. Do not delay.
