CVE-2025-11782
CriticalSummary
Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2. The 'ShowDownload()' function uses 'sprintf()' to format a string that includes user-controlled input from 'GetParameter(meter)' in a fixed-size buffer 'acStack_4c' (64 bytes) without checking length. An attacker can provide an overly long 'meter' parameter exceeding the buffer size.
Risk Assessment
The risk includes potential remote code execution or system crash, which can disrupt industrial operations and cause operational losses.
Recommendation
It is recommended to apply vendor patches immediately and restrict access to the device management interface to trusted networks only.
