CVE-2025-11780

CWE-120Published: 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 'showMeterReport()' 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 vulnerability is a stack-based buffer overflow affecting Circutor SGE-PLC1000 and SGE-PLC50 devices, specifically within the 'showMeterReport()' function. An attacker can trigger this by supplying an excessively large input for the 'meter' parameter, which is copied to a fixed-size buffer without validation. With a CVSS score of 9.8, this flaw poses a critical risk, allowing for potential remote code execution or denial of service due to its high impact on system confidentiality, integrity, and availability.

There is no public exploit known for this vulnerability, and it is not present in CISA's KEV catalog. The vulnerability is remotely exploitable over the network with low attack complexity and no user interaction required.

Recommended Action

Users of Circutor SGE-PLC1000 and SGE-PLC50 firmware version 9.0.2 should apply vendor-supplied patches as soon as they become available. In the interim, restrict network access to these devices and monitor for unusual activity.

Technical Analysis

CVE-2025-11780 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
