Vulnerability from variot - Updated: 2024-08-14 13:19

The Omron FINS protocol has an authenticated feature to prevent access to memory regions. Authentication is susceptible to bruteforce attack, which may allow an adversary to gain access to protected memory. This access can allow overwrite of values including programmed logic. cj1g-cpu45p firmware, cj1g-cpu45p-gtc firmware, cj1g-cpu44p Multiple OMRON Corporation products, including firmware, contain a vulnerability related to improper restriction of excessive authentication attempts.Information may be obtained and information may be tampered with

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.
