Severity

9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The vulnerability is found in the 'AddEvent()' function when copying the user-controlled username input to a fixed-size buffer (48 bytes) without boundary checking. This can lead to memory corruption, resulting in possible remote code execution.

The oldest version currently installed is 1.0.14, as it was the first to be compatible with the existing tariff system, while the latest version of these units is 1.2.21. Circutor recommends not extending the useful life of the SGE-PLC100 and SGE-PLC50 concentrators without keeping them updated. For both the Compact DC units (which replaced the SGE series) and the current GEDE EDC, it is recommended to update to the latest available version (2.0.4) or, at a minimum, to 2.0.0. This approach not only mitigates the identified vulnerabilities, but also provides new functionalities derived from the evolution of DLMS, the PRIME standard, STG protocols and the REST API."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
