Vulnerability from variot - Updated: 2025-11-23 23:51

Vulnerable Upgrade Feature (Arbitrary File Write) may lead to obtaining super user permissions on board.This issue affects BLU-IC2: through 1.19.5; BLU-IC4: through 1.19.5. Azure Access Technology BLU-IC2 and Azure Access Technology BLU-IC4 are both network access controllers from Azure Access Technology, Inc., a US-based company.

Both Azure Access Technology BLU-IC2 and Azure Access Technology BLU-IC4 contain a privilege escalation vulnerability caused by an arbitrary file write flaw in the escalation feature. An attacker could exploit this vulnerability to gain escalated privileges on the system

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.
