CVE-2025-11784

CWE-121Published: December 2, 2025· Updated: Jun 17, 2026

9.8
CVSS v3.1

Official Description

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'ShowMeterDatabase()' function, there is an unlimited user input that is copied to a fixed-size buffer via 'sprintf()'. The 'GetParameter(meter)' function retrieves the user input, which is directly incorporated into a buffer without size validation. An attacker can provide an excessively large input for the 'meter' parameter.

Risk Analysis

This critical stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2 allows an attacker to provide an excessively large input, leading to memory corruption. With a CVSS score of 9.8, this flaw is highly severe and could lead to remote code execution and complete system compromise. The absence of an EPSS score means there is no current data on its exploitation likelihood, but its critical severity warrants immediate attention.

No public exploit is currently known for this vulnerability. Its network-exploitable nature and low attack complexity suggest that a working exploit could be developed and used remotely without user interaction.

Recommended Action

Users of Circutor SGE-PLC1000/SGE-PLC50 v9.0.2 should update to a patched version as soon as one is available. Implementing robust input validation for user-supplied parameters is crucial to prevent buffer overflows.
