Lifecycle Timeline
3Description
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.
Analysis

An attacker can provide an excessively large input for the “meter” parameter.
Technical Context
A buffer overflow occurs when data written to a buffer exceeds its allocated size, potentially overwriting adjacent memory and corrupting program state. This vulnerability is classified as Classic Buffer Overflow (CWE-120).
Affected Products
Affected products: Circutor Sge-Plc1000 Firmware 9.0.2, Circutor Sge-Plc50 Firmware 9.0.2
Remediation
Use memory-safe languages or bounds-checked functions. Enable ASLR, DEP/NX, and stack canaries. Apply vendor patches promptly.
