Vulnerability from github – Published: 2026-09-18 18:31 – Updated: 2026-09-18 18:31

Details

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote authenticated attacker to cause a denial of service or potentially execute arbitrary code on the underlying operating system.

Severity

7.5 (High)

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.
