Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Mitsubishi Electric MELSEC iQ-F series has a critical flaw. <br>β οΈ **Consequences**: Input validation failure leads to **Denial of Service (DoS)** or **CPU module stop**. System halts! π₯
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-1285** (Improper Neutralization of Special Elements). <br>β **Flaw**: **Insufficient input validation**. The system fails to sanitize incoming data properly. π
Q3Who is affected? (Versions/Components)
π **Affected Vendor**: Mitsubishi Electric Corporation. <br>π§ **Product**: **MELSEC iQ-F Series** (specifically FX5U-32MT/ES mentioned). <br>π **Published**: May 29, 2025. π
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Attacker Action**: Can trigger **DoS** or **CPU Stop**. <br>π **Impact**: High Confidentiality (C:H) & High Availability (A:H). <br>π« **Result**: Operational disruption.β¦
π **Threshold**: **Low**. <br>π **Network**: Attack Vector is Network (AV:N). <br>π **Auth**: No Privileges Required (PR:N). <br>π€ **User**: No User Interaction (UI:N). Easy to exploit remotely! π
Q6Is there a public Exp? (PoC/Wild Exploitation)
π¦ **Public Exploit**: **None listed** in current data. <br>π **Pocs**: Empty array. <br>β οΈ **Status**: No known PoC or wild exploitation yet. But risk is high due to low barrier. π
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Mitsubishi MELSEC iQ-F** devices. <br>π‘ **Focus**: Look for **FX5U-32MT/ES** models. <br>π **Verify**: Check firmware versions against vendor advisories. Use ICS scanners. π΅οΈββοΈ
π§ **No Patch Workaround**: <br>π **Isolate**: Segment the network. <br>π‘οΈ **Firewall**: Restrict access to PLC ports. <br>π **Monitor**: Watch for abnormal CPU stops or DoS patterns. π
