Vulnerability from github – Published: 2025-11-27 00:30 – Updated: 2025-11-27 00:30

Details

Astak CM-818T3 2.4GHz wireless security surveillance cameras contain an unauthenticated configuration disclosure vulnerability in the /web/cgi-bin/hi3510/backup.cgi endpoint. The endpoint permits remote download of a compressed configuration backup without requiring authentication or authorization. The exposed backup may include administrative credentials and other sensitive device settings, enabling an unauthenticated remote attacker to obtain information that could facilitate further compromise of the camera or connected network.

Severity

8.7 (High)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N

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.
