VAR-202508-3004

Vulnerability from variot - Updated: 2025-09-30 23:38

Delta Electronics COMMGR has Stack-based Buffer Overflow vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics COMMGR. An attacker must first obtain the ability to compromise a PLC in order to exploit this vulnerability.The specific flaw exists within the handling of packets received from a PLC. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the application.

Delta Electronics COMMGR contains a command injection vulnerability caused by improper bounds checking when crafting a specially crafted .isp file. Detailed vulnerability details are not available at this time

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.
