Improper Input Validation vulnerability in the handling of a malformed IEC 104 TCP packet in the Hitachi Energy MicroSCA

Improper Input Validation vulnerability in the handling of a malformed IEC 104 TCP packet in the Hitachi Energy MicroSCADA X SYS600, MicroSCADA Pro SYS600. Upon receiving a malformed IEC 104 TCP packet, the malformed packet is dropped, however the TCP connection is left open. This may cause a denial-of-service if the affected connection is left open.

This issue affects: Hitachi Energy MicroSCADA Pro SYS600 version 9.4 FP2 Hotfix 4 and earlier versions Hitachi Energy MicroSCADA X SYS600 version 10 to version 10.3.1. cpe:2.3:a:hitachienergy:microscada_pro_sys600:9.0::::::: cpe:2.3:a:hitachienergy:microscada_pro_sys600:9.1::::::: cpe:2.3:a:hitachienergy:microscada_pro_sys600:9.2::::::: cpe:2.3:a:hitachienergy:microscada_pro_sys600:9.3::::::: cpe:2.3:a:hitachienergy:microscada_pro_sys600:9.4::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.1::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.1.1::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.2::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.2.1::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.3::::::: cpe:2.3:a:hitachienergy:microscada_x_sys600:10.3.1:::::::.

▸ How to read a CVE - triage first, then detect and patch

This page is every public fact about CVE-2022-29492, cross-linked. Its job is to answer one question fast - does this need my attention now? - and then hand you the two things you do about it. Here is how an analyst reads it.

Triage: should I act now? Four signals, and they are not interchangeable:

CVSSseverity - how bad it is IF exploited, 0-10. A high CVSS alone is not urgency; a flaw can be a perfect 10 and never actually be attacked. EPSSprobability - a model’s estimate of the chance it is exploited in the next 30 days, 0-1. This is the “will it actually happen” signal. CISA KEVconfirmed - it is being exploited in the wild right now. The strongest signal on the page; KEV beats any score. Weaponisedavailability - public exploits / PoCs, and especially Metasploit modules rated Excellent / Great. Reliable, packaged exploit code means low-skill attackers can use it today.

How they combine: KEV, or a dependable Metasploit module, means patch now regardless of CVSS. High CVSS + low EPSS + no exploit is real but not an emergency - schedule it. Low CVSS but KEV-listed still gets patched now. The verdict above already weighed these for you; this is how it got there.

Then what - two workflows:

Detectwhen you cannot patch today, follow this CVE to the ATT&CK techniques it enables, then Build a SIEM detection (the green button) - author a rule, test it in Atomic, deploy it. That buys visibility while the patch waits. PatchAffected products / packages tell you if you are exposed; Fixed versions by distribution and Vendor advisories give the exact version that closes it.

Reading order for the panels below: verdict + badges, then Public exploits / Metasploit (is it weaponised), then ATT&CK techniques + Sigma / IDS rules (can I detect it), then Affected products / packages + Fixed versions (am I exposed, what patches it), then Threat actors / IOCs (who uses it), then Scoring & timeline / references (the evidence).
