Description

Buffer overflow in kingMess.exe 65.20.2003.10300 in WellinTech KingView 6.52, kingMess.exe 65.20.2003.10400 in KingView 6.53, and kingMess.exe 65.50.2011.18049 in KingView 6.55 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted packet.

AV:N/AC:L/Au:N/C:C/I:C/A:C

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: high.

critical priorityCVSS 2.0 score of 10 with network reachability, no authentication and full confidentiality, integrity and availability impact, plus very high EPSS, makes this a top-priority exposure despite no KEV listing.

What it is

A buffer overflow exists in kingMess.exe in WellinTech KingView 6.52, 6.53 and 6.55. A crafted packet can corrupt memory, allowing remote code execution or a denial of service. The flaw is remotely reachable without authentication, making it serious for exposed industrial control systems.

Impact

An attacker can execute arbitrary code with the privileges of the kingMess.exe process or crash it, causing loss of availability. Successful code execution gives full control of the affected host.

Attack surface

Reached over the network via a crafted packet to the kingMess service; the CVSS vector AV:N/AC:L/Au:N indicates no authentication and no user interaction are required.

Exploitation

Not listed in CISA KEV and no exploit tags appear in the references, but EPSS is 0.61492 (99.1st percentile), indicating a high predicted likelihood of exploitation activity.

What to do

  • Apply the vendor patch or upgrade referenced in ICS-CERT advisory ICSA-13-043-02A; this is the first action.
  • Isolate KingView hosts from untrusted networks and restrict access to the kingMess service with firewall rules and segmentation.
  • Disable or block the kingMess service if it is not required for operations.
  • Monitor ICS-CERT and vendor advisories for updated guidance on this legacy product.

Detection

  • Monitor network traffic to the kingMess service port for malformed or oversized packets.
  • Watch for unexpected crashes or restarts of kingMess.exe on KingView hosts.
  • Alert on unusual child processes or command execution originating from kingMess.exe.

This assessment is produced automatically and is not human-reviewed. Verify against the vendor advisory before acting on it.
