CVE-2025-11782

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. The 'ShowDownload()' function uses “sprintf()” to format a string that includes the user-controlled input of 'GetParameter(meter)' in the fixed-size buffer 'acStack_4c' (64 bytes) without checking the length. An attacker can provide an excessively long value for the 'meter' parameter that exceeds the 64-byte buffer size.

Risk Analysis

This critical vulnerability is a stack-based buffer overflow in Circutor SGE-PLC1000 and SGE-PLC50 devices, specifically in the 'ShowDownload()' function. An attacker can exploit this by providing an overly long input for the 'meter' parameter, causing the buffer to overflow and potentially leading to remote code execution or denial of service. The CVSS score of 9.8 indicates a severe risk due to its remote exploitability and high impact on 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. However, given the network attack vector and low attack complexity, this vulnerability is remotely exploitable without user interaction.

Recommended Action

Users of Circutor SGE-PLC1000 and SGE-PLC50 firmware version 9.0.2 should look for vendor-provided patches or updates. Until a patch is available, consider isolating affected devices from public networks and implementing strict access controls.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2025-11782 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.
