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

9.8

CVSS v3.1

Official Description

Stack-based buffer overflow vulnerability in CircutorSGE-PLC1000/SGE-PLC50 v9.0.2. The 'SetLan' function is invoked when a new configuration is applied. This new configuration function is activated by a management web request, which can be invoked by a user when making changes to the 'index.cgi' web application. The parameters are not being sanitised, which could lead to command injection.

Risk Analysis

This critical vulnerability is a command injection flaw in Circutor SGE-PLC1000 and SGE-PLC50 devices, specifically in the 'SetLan' function. An attacker can exploit this by manipulating unsanitized parameters in a web management request to 'index.cgi', potentially executing arbitrary commands on the device. The CVSS score of 9.8 highlights the severe risk, as it allows for complete compromise of confidentiality, integrity, and availability.

No public exploit is currently known for this vulnerability, and it is not listed in CISA's Known Exploited Vulnerabilities catalog. This 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-provided patches when available. Until then, ensure that access to the management interface is strictly controlled and limit network exposure of these devices.

Technical Analysis

CVE-2025-11779 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.
